I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

There are 6 SATA ports on the "South Bridge" controller (Orange ports). There are 2 SATA ports on the "Gigabyte SATA 2 Chip" controller (Purple ports). The orange ports use the generic Intel SATA/RAID drivers.

Which port do you have the hard drive connected to? Have you tried it in one of the the other ports?

That motherboard has a higher than normal number of complaints on Newegg. It could be defective.

see second post.

I have a 3TB drive D: for data formatted with GPT.

Had BIOS OnChip SATA Type set as "RAID" "As SATA Type" from back in the day. When I took out the RAID, I forgot to change this to AHCI when I reformatted and got rid of RAID drives!

Changing to "AHCI" "As SATA Type" as shown in image in second post, causes Windows 7 x64 to lose / not see the GPT on my drive D: and it wants to "initialize" it as MBR or GPT-- no way!!

A:cloned C:, installed AHCI drivers, changed BIOS to AHCI, D:'s GPT gone

ok, returning to BIOS and setting back to RAID, as AHCI typeenabled me to view the drive D: again
C: drive seems to be running much more slowly again.
these drives are plugged into the OnChip SATAWith AHCI as SATA typeno drive D:

With RAID as SATA typehave drive D:
but C: definitely dog-tired-slow
I really should not have fiddled with this at 3AM on a Sunday morning!!! Bah, I'm a pro, what could go wrong???

I'm not sure why changing to AHCI causes windows to miss the GPT on the D: drive.
Can I back this GPT up and restore it? Detect it after changing to AHCI? this is my only large drive, I can't back up the entire fricking thing.

The other question this makes me ask is how do I keep my GPT when I move to another motherboard? I don't trust the GPT like I do MBR hm....

edit: changing back again, it does not seem any faster. Doing more reading, it's ok to leave it as RAID because AHCI functions are still available no? So I really shouldn't gain/lose any performance?

I bought a brand new SSD, installed it in Windows 7, and there is no option in my BIOS for the SATA controller (to switch between IDE and AHCI Mode). How do I determine whether my computer's sata controller is using IDE or AHCI?

I want to make sure that my AHCI controller is enabled and not IDE when using TRIM.

If anyone can look at the picture below and determine whether my computer is default in IDE or AHCI, then I will mark this as Solved.

Thanks.

Hi
I initially installed windows with IDE enabled on my mobo, then enabled ahci as per the method shown here:

however I still cannot hostwap drives. using another install i had of Fedora i was able to hotswap drives so it cannot be a hardware issue. Is there any way of fixing this problem without reinstalling windows?

You may need to upgrade the AHCI driver from the generic W7 driver to the specific driver for your board from MSI.

Gday people Im almost ready to install my new Samsung 830 series SSD 256GB drive (some miner screw issues means I cant do it tonight).
Now do I need AHCU enabled for my E-Sata connection or is IDE ok ?

Also should I upgrade the BIOS and can someone point me to a tutorial for that?
Cheers

A:Installing a new SSD on my Asus UX32VD do I need AHCI enabled?

Look for a BIOS upgrade on the Support Downloads webpage for your exact model. The instructions for running it will be on it's download page or in a ReadMe file which is extracted with the installer, so pay attention to where it extracts the file and browse there first before running the installer.

Some owners are hesitant to install a BIOS update if it doesn't specify needed improvements, but I always upgrade the BIOS at reinstall because there are sometimes improvements not specified.

As a matter of course I also always enable the most modern AHCI mode in the BIOS when checking if the new SSD is detected after unplugging all other HD's and installing the SSD. In the rare case that the install fails you can try IDE mode to see if that remedies the failure.

Study over the steps in Clean Reinstall - Factory OEM Windows 7 which will assure you get and maintain a perfect reinstall if you stick with the methods and tools therein.

Hello.


Just be advised if you change the settings at all you may lose access to all the data, especially the RAID, if you're not very aware what you are doing then it's best left as is.



The tutorial linked below will give you some of the basics, but you have been warned.

I understand that if I wanted to get a SSD (such as the Vertex 2), I would need to enable AHCI in the BIOS.

However, I have pullout chasses in my PC which allow me to swap in and out about 7 different hard drives that I use for various data storage. I also have one hard drive which is an XP boot and another which is a Windows 7 boot. I am currently using plain old SATA in the BIOS.

Can anyone please explain what effect turning on AHCI would have to my system? Would I still be able to access the data disks? Would I still be able to boot off the bootable disks?

Thanks!
 

A:AHCI in BIOS

It would be best to start the Advanced Host Controller Interface (AHCI) with a fresh install of Windows. All 3 of my drives are SATA and configured in a 1TB striped RAID. ACHI is automatically enabled when using a RAID array. The data on all your drives may disappear when they are connected when you enable ACHI

A:AHCI Bios Setup for SSD?

It is possible that the registry setting that you changed only supports the Microsoft AHCI drivers, not the Intel ones.

I don't know whether it'd be practical to uninstall the Intel drivers.

If all else fails, a re-install of Windows with the SATA controller set to AHCI in the BIOS should work fine. You should not need to install any third-party driver to install Windows on a drive that uses one of the Intel SATA ports.

Hello people, i'm new in this forum so i'm sorry if i shouldn't post in this section
so i just bought a new SSD (850 evo 250gb) And it says on it's software i should enable AHCI mode on my bios
to get it faster. also the tests results show 250 when it was supposed to hit 520-540, and i think it's due to not having
AHCI mode, but i tried to change it in my BIOS, but i only have these 3 options:

- S-ATA+P-ATA
- S-ATA (which is the one i'm using now)
- P-ATA

Isn't there any other way to change it to AHCI mode?

As for your boot problem, it sounds like the BIOS setting reverted to default and Asus ExpressGate was enabled afterward. The BIOS can reset if you removed the 3v battery from the motherboard, but it can also reset if you caused a short circuit while removing parts, even for a brief second.

You can disable ExpressGate in BIOS. That 'feature' will slow down boot time. Also enable 'Quick Boot' and disable 'Full Screen Logo'.

If you moved things around in the PCI slots it is always a good idea to perform a ClearCMOS (CLRTC) procedure afterward. This forces the system to re-recognize all devices and it resets the BIOS defaults too. It may also clear up any configuration errors that are delaying boot.
The procedure is in your motherboard manual, or ask here.

A:AHCI BIOS Not Installed

Look at this helpful Thread that relates a little to your issue.

http://www.techspot.com/vb/topic18329.html

Seem that error is the raid bios, according to that thread you need to go into Bios and find the SATA operation and turn it from "Raid Autodetect AHCI" to combination. At least that is what that thread says, I have no personal experience with this but if you are not using raid why leave it on to cause issues.

Hopefully that helps.

My current computer is a inspiron 530s running Windows 7 (of course) and in it there isn't an option in the BIOS for AHCI mode. I have the newest version of the BIOS and was wondering if there might be something else I might could update or change to make the option available. Thank you for your time and i'm sorry if this isn't the best place to post this thread on the forum.

A:No AHCI mode in BIOS?

Concealed10,
Welcome to SF. You will want to visit the Dell site to see if a newer bios version doesn't address this very issue. If it does then you will want to back up all data and research in the Dell manual the proper way to do a bios update as any false move can brick your rig. This isn't to say that it's not straight forward but you must adhere to the procedure.

Hey All,

I'm purchasing a new SSD next week. I've been reading up on it and it looks like I need to enable AHCI in my BIOS. I can't find any option for AHCI though.

I currently have my System setup as RAID0. This was how it was set up in the factory and I haven't changed it.

The only option I have is under SATA operation and I can either set it to "RAID Autodetect/ATA" or "RAID ON".

Is there anyway I can check to see whether AHCI is already enabled? If not will one of the above options enable it?

A:How to Enable AHCI - No option in BIOS.

Some motherboards incorporate AHCI SATA automatically. In the early days of SATA there was a lot of confusion in terminology. "RAID" - "AHCI" - all the same thing.

For your motherboard it looks like you want to choose "RAID Autodetect/ATA" to use a non-RAID setup with AHCI.

Bud,

Your manual should explain the difference. Unless you are using a RAID configuration, and your Motherboard can handle it, select AHCI.

You may need to install its drivers.

I have an older Gigabyte mobo, still on SATA2. There were 3 settings in the mobo that deals with IDE vs AHCI, I changed them all to AHCI. I also notice in the BIOS where it says "IDE Master 0", my SSD isn't listed there, it just says None. When I rebooted, there was an additional post screen that says it's searching for AHCI devices, then it says it didn't find any. I installed windows 8 anyway and it worked. I used AS SSD benchmark to confirm that it is running AHCI and aligned properly. So, according to that, I'm running on AHCI, but everytime my computer boots up I still get that same message: searching for AHCI devices and not finding any. What's wrong here?

A:SSD seems to be running in AHCI but BIOS not detecting?

Same is happening with my MB (check my sig), it doesn't show in boot menu but it's there when choosing default boot drive. My guess is that they were not ready for SSDs at the time. I scared me first time I put SSD in, thought it was DOA. It does show properly when in IDE mode but that's not good for SSD.

I just upgraded an HDD to an SSD in a HP laptop. The BIOS does not show any SATA options at all. How can I figure out from within Windows 8.1 if AHCI is enabled?

Relevancy 55.47%

Hi all
It will mean a fresh CLEAN install of Windows I'm afraid but if you have decent SATA disks change the default setting in the BIOS from IDE to AHCI.

It really WILL improve system performance --one of my big bugbears on any discussion on performance is how the I/O subsytem (generally Disks) is forgotten - yet on most home computers the I/O subsystem is often the real cause of dreadful performance.

You'll have to do a windows CLEAN install as the system will BSOD if you just change the BIOS so you won't be able to run the installer from within Windows itself. (If you can you are very lucky).

It won't effect any Virtual machines you may have however (apart from improving disk performance).


Cheers

A:Change IDE to AHCI in BIOS - Much better performance

I went back and forth between AHCI being on and being off on my new box that I built in July. Honestly, with almost ever task I did and with any benchmarking tool, I didn't see any real performance gain with AHCI enabled.

Unfortuantely, with AHCI on, I do have about an 8 second delay on each boot as the storage controller initializes. And since I do boot daily, and it was costing me 8 seconds which I didn't pick back up elsewhere, I just run with AHCI disabled.

I have an Apricorn SOLO-X2 with SSD drive as my boot drive (cloned from my IDE drive). The setup required setting AHCI mode in both Windows and BIOS. It works great.

But NOW I may have to re-install windows (due to problems unrelated to the drive). The official installation disk does not see the SSD.

I think I can pull the SSD from the SOLO adapter and connect it directly to the SATA cables and install from there, setting AHCI off in BIOS, then setting it back on again in BIOS & windows after the install.

BUT, I'd like to know if there's a better (less painful) way.

A:reinstall win7 from CD AFTER setting AHCI in BIOS

You most likely need the pre-install drivers. But I can't see such a link on Apricorn website. Perhaps you have a CD that came with it?

- Anyway you should be able to install Windows by removing the SOLO-X2 (and the SSD) and attaching the SSD to a SATA port.
- After the installation reinsert SOLO-X2 to PCIe port (keep SSD connected to SATA port).
- Log into Windows, drivers will install automatically.
- Shut down PC, put SSD in SOLO-X2
- During boot up, enter the BIOS of your computer and assign the SSD on the Velocity Solo as your boot device.

I installed the most recent version of Win 7 7229 on my vertex 60Gb V 1.3 SSD the other night and after the first reboot the bios stopped when trying to discover the drive which is on '0'. The bios is set to AHCI (as it has always been with previous builds). If I change it to IDE then the drive is recognised and things go smoothly from there although the drive transfer rate in windows experience has dropped from 7.3 to 6.8. I have reflashed my bios but still the problem remains. I've swapped the leads round on my HD's but it still hangs when it reaches the Vertex drive.

Can anyone shed any light on what might have happened

A:HD recognized by scandisk but HD not recognized by BIOS

probably the booting sequence is wrong due to the fact that you told the BIOS to load the preferred defaults. If you have a standard BIOS:

*go to advanced BIOS settings.... your going to see a big list of options .

<< check this picture for visual example>>
*take a look at the first , second and third boot device and change them to:

1- HDD - 0
2- HDD - 1
3- HDD - 2

Alternate them accordingly.

**probably the reason why your pc booted up at 16 bit the first time , may be
because you haven't installed the drivers for your video card yet.

I wanted to be able to hot swap drives, on a Gigabyte GA-Z97-GAMING 3 M/B. Seems the Gigagbyte BIOS has 3 SATA MODE SELECTION options:
IDE, AHCI and RAID. It was set to RAID, which makes sense as the D drive is a pair of matched SATA III drives in a BIOS (software) RAID 1 pairing. C drive is an SSD with the OS on it. However this option doesn't seem to allow hot swapping, even though all drives are set in the BIOS with hot swapping enabled.
Setting the SATA MODE SELECTION parameter to AHCI doesn't allow booting, and I am afraid of enabling AHCI in the registry in case "something bad happens" to the RAID. What will happen if I both set AHCI in the BIOS and set the Win 7 64 bit registry for AHCI? Will the RAID1 Intel Rapid Storage Technology software RAID 1 pairing still work, and will I then have hot swappable drives? Thanks.

A:BIOS, RAID 1 and AHCI hot swappable drives question

Edit: Putting the edit in the beginning, but do read till the end please. You have a separate controller named Marvell? 88SE9172 chip, try setting this as AHCI in BIOS and attach the drives you want to hot-swap to GSATA3 ports 6-7(grey ports?), see if it works. Maybe you wont have to change to AHCI on your Intel chipset after all.

Hey, I have an older AMD Gigabyte board but things may be similar. I will share my experience.

First of all, in BIOS I have 3 different sets of options for IDE/RAID/AHCI. Namely, E-Sata ports (x2 SATAII), GSata (x2,SATAII) and OnChip SATA (this is the SB850 SATA ports,x6 SATAIII). E-Sata and GSata are both controlled by Jmicron chipset.

When I installed current OS a month ago on my new SSD, I installed with OnChip SATA mode set as RAID as I had 2x1TB BIOS raid0 and 2x640GB BIOS raid0 that I didn't want to break. The RAID option in theory is just a subset of AHCI and should have the same functionality. However, Samsung Magician program for the SSD had problems recognizing the SSD properly. So I had to change to AHCI.

You can definitely change the registry to load msahci(and IAStorV on intel?) on startup, it is just another driver to be loaded, OS will continue to use RAID drivers as long as BIOS is set to RAID. However, you will lose your BIOS raid once you switch to AHCI in BIOS, they will be back if you change back to RAID once again (just don't do anything to them in windows ). I backed up my data and set-up a new windows raid0 in disk management and it is working alright atm. So losing your BIOS software raid is not that much of a problem imho.

Now the interesting part is, although OnChip SATA ports are set for AHCI, non of the drives attached to these ports are hot-pluggable. They simply don't show in Safely Remove Hardware. Not that I want these show as removable mind you.

For hot-plug ability, I use E-Sata ports which are set to AHCI as well and had to install the corresponding JMicron drivers. The HD I use for backup purposes is connected to the PC with a SATA-to-ESata data cable and I have an adaptor that can supply 12V+5V 2Amps that has a molex ending, which in turn has a molex to sata power converter. I can hot-plug this disk and just use safely remove hardware like any usb stick/hdd. Now, this may not be what you are looking for, I just wanted to show you even though both chips are AHCI one of them doesn't list drives as hot-pluggable and the other one is.

The above setup is working alright for me so I have not looked into it further but there may be one other option that you can try. 2 weeks ago I had to work on a friend's laptop and his internal drive was showing as removable and I had to do a registry edit to mark it as internal. Perhaps the reverse can also be done?

My internal SATA device appears in Devices and Printers and in the - Microsoft Community

Also, keep in mind that when 2 drives are connected to the same power cable, if you hot-swap one drive it may kill the power to the other drive that is supposed to be keep working.

By the way, you didn't mention why you want hot-swap. Do you have some other drives for backup? You can't hot swap the OS or raid drives anyway.

Hopefully someone more knowledgable with your board will come along and answer proper.

A:W540 SATA Option (RAID or AHCI) gone after BIOS up...

Did you order your system as RAID model?  W540 does not come with RAID by default.  Lenovo has to license RAID option ROM (costs $) so it is only provided if you order RAID model from Lenovo.  As far I as I know, the only RAID model in Europe is 20BG001Sxx.  And your 20BG001Cxx model came with only 1 disk.  If I am wrong about this, please let me know.
 
I believe there was a bug in 1.05 that mistakenly enabled RAID on some non-RAID models.  The bug was fixed in 2.05, so unless you really have a RAID model W540, then RAID would become properly disabled on your system.

> I am having difficulty updating BIOS for a Toshiba Tecra A9 -11i laptop, (using latest update from the official toshiba european site); after running the bios launcher (version 3.2.8)
I get the following message ' this computer is not supported"? The current installed bios version is 1.5 , date 7/5/2007

This error message appears if you want to update a BIOS which is not compatible with your notebook model.
Toshiba European driver page provides the 2.10Win BIOS for this notebook model.
So you used definitely wrong BIOS.

> there's no response when pressing the ''FN' key and one of the f number keys
Common modules controls the FN buttons.
So the issue should be solved installing Common Modules v 6.06.00, Utilities 4.30.15
Note; You have to press FN + 1, 2, 3 etc? DON?T press FN + F1 etc?.

> I also having difficulty getting AHCi' mode to work in Windows XP Pro SP3; I have intel chipset 965m +ICH8M, the Intel ICH8M serial ata storage controller-2828 shows in device manager- the matrix storage manager won't run so i copied the file iastor.sys from the matrix manager folder into C:/Windows/Driver/system32 and edited the registry as read elsewhere on the forum but have had no joy.

Firstly be sure that AHCI is enabled in BIOS!!!
Furthermore the Intel Storage Manager controls the AHCI so you should slipstream the AHCI driver to the Win XP CD as described here:

Hi everyone I've got a Latitude D820 and I really like it. I'm really interested in getting an SSD to put in this system but I have my doubts. I have been told that SSDs only really like being in ACHI mode but the D820 doesn't have this option in the BIOS. I've also been told that SSDs running in IDE compatibility mode will cause bluescreens and have slow performance.
I did some digging around and discovered that Dell have hidden this option from BIOS setup for the sake of saving time, answering costumer support calls regarding SATA operation and drivers.
So my question is, will Dell be able to release a new BIOS revision with this feature enabled? The D820 is still a capable and i would hate to see it crippled in this way.
Thanks in advance for any replies.
George.

The registry setting for msahci is still at the value zero.
The system was rock solid with a Samsung 840 EVO. Samsung Magician indicates it is unable to detect SATA interface details.

This is the first time I've seen it, and I haven't touched the inside of the computer or changed any settings. The only thing I've done is upgraded to Windows 7 Professional.

Does anyone know how to get this to go away? I hardly shut down my computer now so I can avoid the extremely long startup process.

After a Windows 7 update today my computer turns on, goes past the welcome screen, then shows up with an error reading "AHCI BIOS not installed" and something about clicking on CTRL+S to enter setup and then restarts. This keeps on going continuously until I shut it down. I've read suggestions on forums to run chkdsk but I can't get as far as the Advanced Boot Menu; I can get to the setup and regular boot menu and when I boot from my hard drive the computer restarts.

Any suggestions?

I partitioned my hard drive a week ago and installed Ubuntu on it. However, I think the error is due to my update today.

AHCI is an advanced controller interface for sata drives and it

If you are not using it,might want to disable it in the bios setup.
If you are using it,I can try to find the registry hack that enables
it in windows without reinstalling,but you still need to see if you
can disable it and get into windows first.
Set it to sata or ide,whichever is available.
Not raid or ahci.

I don't have any anti virus software, I don't have Hyper-V (windows 10 home edition, upgraded from Windows 7).

A:Virtualization enabled in bios but not working

In Windows 10, Hyper-V must also be enabled in the "Turn Windows Features on or off" portion of the Programs and Features element in Control Panel, to wit:

The checkbox next to Hyper-V must be checked (turned on) and the system rebooted, for Hyper-V to function on a Windows 10 PC. It is not turned on by default.
And ooops! while I'm thinking about it, my recent online check confirms that Hyper-V is not an available feature on Windows 10 Home. It is only available in the Pro, Enterprise and Education editions of Windows 10. But even in those editions, it must be turned on before it can be used. Here's a Spiceworks post to confirm: Is there no way to use Hyper-V Manager on Windows 10 home? - Virtualization - Spiceworks.

When I Run Hardrive Temperature Monitor Programs...it Says S.m.a.r.t. Not Enabled....yet It Is Enabled In The Bios.
 

A:I Enabled S.m.a.r.t. Monitoring In The Bios...but Its Not Working

Turining SMART checks on in the BIOS does not "enable" smart. It only tells BIOS to check the SMART status of a hard drive at bootup and complain if it is (supposedly) broken.
SMART is completely done by the hard drive itself and it is up to the drive how many SMART functions to implement or whether to have the functionaility turned on or not.

Maybe you HD just doesn't have SMART or the temperature monitoring capability? Or, maybe the monitor program doesn't know how to interpret the temperature values of your specific drive?

Also, you cannot do SMART on RAID arrays. So if you have some fakeraid controller, it may be masking all SMART information.

You should use the definitive SMART utility - smartmontools to take a look at your drives and enable SMART if needed.

Hello I have recently purchased Precision laptops with the intention of using them for research on Intel s new Software Guard Extensions SGX These laptops come with the required CPUs that support these new CPU instructions and we thought the required BIOS support as well In the BIOS for the laptops there is an option for enabling SGX but when enabled we are not able to install any of the official Intel SDKs on Windows OR Linux Additionally we ran an SGX test program that would dynamically detect the Dell Not BIOS being Intel SGX Enabled SGX features using Dell BIOS Intel SGX Not being Enabled CPUID and Machine Specific Registers MSRs It successfully detected the SGX hardware support i e the SGX instructions are physically on the CPU chip but it showed Dell BIOS Intel SGX Not being Enabled that the BIOS flags controlling the startup of SGX were not enabled possible SGX specific MSRs have not been set The specific CPU flag that needs to be set is described here https github com ayeks SGX-hardware Here is a quote from that page that describes what is needed for SGX to work quot The CPU and the motherboard BIOS must support SGX SGX Dell BIOS Intel SGX Not being Enabled is turned off by default and must enabled via MSR IA Feature Control SGX Enable Only the BIOS can make changes to the IA Feature Control quot For reference we are using the latest BIOS version for our model - version A Also the CPU we have is the Intel Core i - HQ CPU GHz I hope we can resolve this issue in a timely manner as we are not able to use these laptops for their intended purpose SGX research

Hey guys,
So a few months ago I was trying to run an android vm using GenyMotion. The app I wanted to use, however, required it to be running with hardware assisted virtualization, which I enabled in the BIOS. I downloaded the microsoft HAV and tested it, and it told me that virtualization was supported on my computer, but was not enabled. I have checked and rechecked several times since then and it is enabled in the BIOS. However, the tool still says that virtualization technology is not enabled. What can i do? Is this an issue or is there something I'm missing?
Thanks in advance

A:HAV says virtualization disabled, I have enabled it in BIOS

What are your Hyper-V services (win-key + r, type "services.msc") set as?

Hey everyone!

So i bought some new ram as I use to run on one stick, (1 x 4GB) this new ram was compatible with my motherboard so i bought (2 x 4GB), i will list everything you guys would need to know spec wise:

Processor: AMD ATHLON X4 760K QUAD PROCCESOR

MOBO: GIGABYTE F2A58M -HD2

RAM: HyperX FURY Series 8GB (2x 4GB) DDR3 1866MHz CL10 DIMM Memory

But i know its not a hardware thing as all my sticks work singularly in both slots, but it does not pick up two sticks.
http://prntscr.com/9wy5gp

This is a picture of my computer on the bios, as you can see it knows two sticks are installed, but only one is enabled, how do i enable both?

Many thanks!

I have an issue with the SATA BIOS settings which have options for configure as IDE or set it to as AHCI So now I can only boot Vista when it is set to AHCI and only boot the XP when the BIOS SATA is set to configure as IDE and if not it gives a stop code error B And I did search for a ASUS P QL Pro motherboard BIOS update and I have the lattest version apparently AHCI BIOS Vista motherboard only can settings ASUS Solved: boot Also I did look in each one s Device Manager to check for driver updates such as for the serial ATA controllers So how can I boot both without changing the BIOS setting each time I dual boot with the Vista boot Solved: ASUS motherboard BIOS AHCI settings can only boot Vista manager and in my motherboard manual it does say quot Due to Intel chipset driver support regulation the AHCI mode is not supported in Windows XP environment and is only supported by Vista with OS built Solved: ASUS motherboard BIOS AHCI settings can only boot Vista in driver If I try to boot either XP or Vista without changing the SATA BIOS settings it gives stop code B nbsp

A:Solved: ASUS motherboard BIOS AHCI settings can only boot Vista

Fixed by changing the BIOS SATA configuration settings from that AHCI to IDE, enhanced. And then reinstalled Vista so that both XP and Vista use that same BIOS setting.

So after I changed to SATA AHCI mode in the BIOS the main boot internal hard drive shows as a removable device in system tray So how do I fix this issue and I did follow the instructions in the Microsoft Knowledge Base article http support microsoft com kb to enable the sata driver first before I changed the BIOS setting However in the Vista on the same hard drive in the same removable shows SATA BIOS drive AHCI to in after mode the change computer after change to SATA AHCI mode in BIOS the drive shows removable with the same SATA AHCI fix done to enable the needed drivers the internal hard drive does not show in the system tray as removable So possibly if I install the Intel Matrix Storage Manager from their site for this ASUS P QL Pro motherboard with a Intel P express chip set known as ICH then after a re-boot it may no longer show as removable This computer is a store built desktop that has only one GB SATA hard drive installed I had it set in the IDE compatible mode so that I could mult-boot with XP Vista and Ubuntu Linux

A:after change to SATA AHCI mode in BIOS the drive shows removable

That's not an issue at all, and it's perfectly normal. AHCI offers, on some boards, hot swap capabilities. It's nothing to worry about.

I have a pavillion dm4. I want to be able to press the F1-F12 keys without having to hold the fn button down and have it respond with the action key (brightness, colume, pause/play etc.) I have gone into the BIOS and made sure that the "action keys" prompt is enabled so they should work without having to press the fn key, but unfortunately they dont. Even with it enabled the only way to use them is with the fn key. It was not like this until one day I turned on my computer and they it just randomly started doing this. Anyone know what happened or how to fix this?

Hi there,

Recently I turned on Fast Boot option in BIOS and now I can't access again BIOS.
I try press F2 soon after power is on but is not working.

Have you got any ideas how to enter to BIOS?

A:Fast Boot enabled - How to access BIOS?

Hi

Fast boot can be enabled or disabled within the running windows system.
Toshiba preinstalled application called ?System settings? allows you to load the default settings.

In case the Windows 7 is preinstalled, check the tool called ?Toshiba HWsetup? which should appear in All programs -> Toshiba

But you should also be able to access the BIOS press INS button and then F2 button
Try also F12 button. Now in the boot menu should appear where you could choose the option ?Enter Setup?.

This will allow you to access the BIOS

If you guys/gals have any free time at all today I've got something nasty brewing on my home desktop PC. First off, I'm connected to the internet through a hardline/cable modem which is plugged directly into my wireless router which is then plugged into my desktop through one of my router's ports (fairly standard setup). The desktop displays a message that it is connected however firefox just starts and then is killed by some rogue process. Internet explorer cannot connect to the internet and I cannot start my antivirus software. I fear it may be the dreaded zero access trojan but I'm not sure.
Some further detail. I ping google.com and I get nothing. Under ipconfig /all I can see that the netbios tcp is disabled even though I can see that the service is enabled. I also see a message for "media disconnected" using ipconfig /all.

I hope you guys can help. I was running Nox app player just fine for weeks. The other day it started running badly and reported that I should enable vt in bios. It is enabled in bios. Task Manager reports virtualization enabled under cpu. AMD virtualization util reports that it is not enabled though. I flashed bios to most recent version and disabled then re-enabled SVM. I also enabled and disabled Hyper-v (it was not enabled when Nox was running fine). I updated to most recent version of Nox as well. I don't know what I could possibly be missing.

A:Switching BIOS SATA RAID/AHCI setting causes BSOD at Windows Start

This is a hard one. As I'm sure you know, there should be no difference (to Windows) for RAID vs AHCI. It is normally the same driver, and the same registry setting.

So here is my WAG: maybe you need to have all 3 hard drives connected to break the RAID and change to AHCI.

Once completed, you would then remove the extra drive. Hopefully you have not formatted or changed that drive at all.

I have the same problem.  I believe it is a BIOS problem related to the APCI chip.  I just bought my system and HP wants to send out a tech and charge me $200 to make it work, but the guarantee it will work when they leave. Probably not likely.  Customer support on this is terrible.
