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.)

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 everyone,

I have a Dell Inspiron 530s. It has a 2.53Ghz Core 2 Duo, 3GB RAM, 320GB HDD.

The last two times I started up the computer, it started up MUCH SLOWER than before. It took forever to get through the Dell splash screen. It used to take 10 seconds to get through it, but now it takes more like three to five minutes. After I get past the flash screen, it flashed "AHCI BIOS not installed"

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.

Thanks in advance!

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

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.

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.

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.

A little while ago I noticed that my motherboard's BIOS was configured to use IDE instead of AHCI I don't know if I installed Windows while it was in IDE mode and didn't realize it or if the BIOS just switched it by itself can it do that I've BIOS Issues and AHCI read there's a way to switch it back to AHCI mode without requiring a reinstall by going into the registry and modifying the values for msahci and pciide before restarting and switching to AHCI That doesn't work for me though BIOS and AHCI Issues What ends up happening is that in the POST screen the motherboard will detect the DVD drive fine but when it tries to detect the hard drives it'll say something along the lines of quot Auto detecting SATA quot and then just stay there I don't know BIOS and AHCI Issues if it actually progresses after that since I didn't have the patience to wait but the point is that it shouldn't be taking that long It doesn't even boot into Windows My real question is this Is there something wrong with my motherboard My computer is getting a bit old years and I have noticed that the motherboard is taking longer to detect devices Before the computer would show the motherboard splash screen immediately but now it displays quot Loading ASUS Express Gate quot for a few seconds before doing so Afterwards it also tells me that it can't detect a hard disk for a split second before booting into Windows I think all of this started happening after I unplugged everything to clean out the computer I might've rearranged some SATA plugs too and then plugged everything back in If this isn't a problem with Windows is it possible that the motherboard's AHCI or SATA controllers failed Or maybe it's a problem with my hard drives' SATA controllers I can boot in IDE mode but not AHCI mode

A:BIOS and AHCI Issues

This is the tutorial for how to switch to AHCI if W7 was installed in IDE mode:
AHCI : Enable in Windows 7 / Vista

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: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.

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.

This is the message I keep getting on boot up. I was messing around in the bios before I was getting this message. I managed to reinstall Windows 7 and it is working fine. The hard drive is Sata. I may have plugged it into another sata port on the board. Anyone have a clue how I can fix this?

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.

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.

As far as I know BIOS update doesn't offer some additional options. Please check BIOS settings again. In advanced BIOS options there should be SATA option and there you can change between compatibility and AHCI mode.

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.

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.

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.

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.

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:Tecra A9-11i: Bios update problem and AHCI not working

> 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:

A:When to use RAID, AHCI or IDE options in BIOS during windows installation?

More than likely you won't be using raid. Which of the other ones you use depends upon your hard drive type. You use AHCI for SATE and IDE for IDE. Have you tried google?

Hi all,

I installed the x64 version of Win 7. After that I changed the registery and then changed the SATA selection mode to AHCI (which was in IDE mode before) in BIOS.

But;

1- One excessive icon has been appeared in bottom right-hand corner (as is in below image). When I click on it, a small window appears that says:

Open devices and printers
Eject ST500DM002-1BC142 ATA Device (this is my HDD!)
- ...(C)
-....(D)
-....(E)

I think it belongs to the HDD. How to get rid of it?

2- Should the settings of the BIOS (SATA selection mode) always be in AHCI and don't I need to return it to IDE even if I want to re-install the (x64 or x86) OS?

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.
 

A:AHCI BIOS not installed & Continuous restart loop - Windows 7

AHCI is an advanced controller interface for sata drives and it
is usually a setting for the raid controller.
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.

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.

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.

Do you have a single drive or multiple drives setup in a RAID configuration? The message you are seeing is fine (and normal) if you have no RAID. It usually will just pass it so quickly that you didn't notice it was there. How long have you let the pc set at that error message?

So, I hang the optical drive and the port for the e-SATA connection to the external backup drive off it and run it in IDE mode.

Hi

I am using Windows 7 RC x64 Ultimate on a Gigabyte 965P-DS3 Rev 3.3 mobo with F14 (non-beta) BIOS.

I noticed in SETUP recently that the SATA Mode is set to IDE.

When trying to change to AHCI the system will not boot.

Is there a SAFE (ish-lol) method of changing to AHCI mode and would I benefit?

Thanks
 

A:Solved: Change from IDE to AHCI safely?

This should do the trick. Looks like all it takes is changing one key to enable the AHCI driver:
Error message when you start a Windows 7 or Windows Vista-based computer after you change the SATA mode of the boot drive: "STOP 0x0000007B INACCESSABLE_BOOT_DEVICE"

As to whether you'll see any benefit it's doubtful, though a performance measuring program may see better numbers for some disk transactions.

The main benefit is the ability to hot swap drives (NOT the boot/system drive of course) if the motherboard also supports hot swapping.

IDE is to use the SATA drive as "Parallel ATA physical storage device." AHCI "allows the onboard storage driver to enable advanced Serial ATA features...."

Hi, Thanx to shuttles indescript site I have killed my AI61 motherboard, I thought I was getting an executable zip which was actually the flash program + rom and after opening BEEEEEP

Anyway I have a eeprom burner and this eeprom sst39sf020 is right in the list.

Can anyone email me the bios .bin file for this motherboard? (not the file from shuttles site but the old bios file ai61s017.bin so I can flash it using my eeprom burner)

Or at least tell me how to extract the .rom from the exe file shuttle sends

If I get the rom file I will be able to revive this nifty old 750!

Q: Ahci

Hi to all,

How can I set the Hard drive (operation) to AHCI in Windows and BIOS? Working in BIOS is simpler because it has a limited number of menus.

A:Ahci

If your BIOS has the mode setting at IDE and Windows was installed in IDE mode then you must do some preparation before making the change. Windows will not start if you just switch the mode to AHCI.

To change the mode in BIOS you need to find the settings for the SATA controller, usually "Storage Configuration" (or similar) > and then the setting for "Configure SATA as" .

To allow Windows to start in (the changed) AHCI mode you need to make a Registry edit as detailed here:
AHCI : Enable in Windows 7 / Vista

The procedure is:
Make the Registry Edit
Restart the computer
Immediately go into the BIOS settings
Make the BIOS setting change > Save & Exit

If your ssd doesn't have any problems wiuth AHCI on, then definately use AHCI. It will help the performance of your ssd.

Q: AHCI

I am going to be buying a new SSD drive. I will need to install Windows 8 on it. I had AHCI already enabled in my BIOs since I had an SSD drive already installed with Windows 7. So this will be an upgrade with new drive and new OS. What I need to know is this. When installing Windows 8 what do I need to do prior to enabling AHCI? Is there a driver I need to install from a flash drive? It seems that I did something similar when I did my old install of Windows 7. I have a 880 Gigabyte board/AMD chipset. Thanks in advance for any help on this!

A:AHCI

If it is new SSD it should be preformated so all you'll have to do is to install OS as per usual. Win7 and 8 will detect it properly and install drivers.

Q: No AHCI

On my work PC I've changed the registry setting and rebooted but it didn't install the drivers. In Device Manager there's no AHCI. Can't boot if BIOS is set to AHCI because there is none according to Windows. I've tried everything I can think of.

Any ideas?

Hey Tw33k

Did you follow Bare Foot Kid's tutorial here: AHCI : Enable in Windows 7 / Vista ?

You have to be sure to do it in the exact order:
Make registry change > restart and go directly into BIOS > change to AHCI > Save and Exit to boot into Windows > Restart after driver install.

Hope that helps!

Q: Ahci

Since I moved W7 to a drive that has AHCI enabled in the BIOS, but the image that I used of W7 was on a regular SATA drive previously, I didn't see the need to enable it in the OS. However, when I now transfer files from the AHCI drive (OS) to a regular SATA, I'm getting considerably lower transfer rate than before. Is this because of the current configuration?

Since the OS drive is the only one that is AHCI capable, would having AHCI enabled in the OS have any adverse effects on the other drives?

I read in the tutorial that AHCI had to be enabled in the BIOS before installing the OS, but since I didn't do a regular install, should I follow the tutorial's procedure for enabling it in the OS now, or would simply installing the AMD AHCI driver be sufficient?

Are you sure AHCI only effects the OS drive? I thought it effected them all. In fact, I've never heard otherwise and only ever hear of it being for all drives. Some raid configurations (Raid 0, etc) have multiple drives and distribute data to both drives. They need to be set on the RAID configuration (which uses AHCI) in the BIOS. http://en.wikipedia.org/wiki/RAID (the irony of using Wikipedia as a source. Oh well its accurate most of the time).

And no, it has no adverse effects on the other drives if it is enabled.

It does need to be enabled in the BIOS, and you do need the AMD AHCI driver (It probably will work without it, but why not have the correct driver installed? It can only help... usually). If it isn't working for you because of the OS transfer, try enabling it with the tutorial: AHCI : Enable in Windows 7 / Vista

I just finished reinstalling windows and I'm having issues with the sata operation again. With the factory selected default of AHCI and flash cache module enabled, it blue screens. When I disable both it will boot.

I then tried to download drivers from dell. I downloaded the intel matrix storage manager and intel turbo memory (applications and drivers) but my computer will not let me install them. It says my machine does not meet the minimum requirements (which it does because I had it working before)

I was just on the phone with dell for over an hour thinking they would have a quicker solution. After finally deciphering my techs dialect he had no useful info. I am going to try and create a bootable cd with the drivers on it while I wait for the wizards out there to solve my dilema...
 

A:ATA to AHCI

That is because you have to start out with AHCI enabled in the BIOS before installing the OS.
Have the Raid drivers for your board ready on a floppy or flash drive, or add them to your install disk.

What Intel Board are you using?

Acutally, depending on the board, you may not need drivers ready to load. Just enable AHCI and reinstall the OS from scratch.

Hey all

I have recently bought a new SSD (replacing the main HDD) and, as you do, have been tinkering.

I read that for best performance it should be set to AHCI, so I followed this with no issues:

AHCI : Enable in Windows 7 / Vista

However, when I went into the bios I realised that the M2N68-AM Plus does not support AHCI.

Slight panic, but the PC booted fine (huzzah!).

So my questions are - leaving the registry with the settings as 0, will that cause any issues in the future? I read in one forum that a user did this and then 6 days later it went to poos.

If the answer to that is "no", will it in fact improve anything at all?

thanks

A:SSD with AHCI

If the board doesn`t support AHCI, it doesn`t matter what you do in windows.

All that matters is the speed of the sata ports.

Your board only has 3 Gbps sata ports. It`ll be fine.

Were I change to ahci mode for ssd ? Bios not has a option !Thank,s.

A:AHCI.

Greetings, Your PC supports IDE mode.  An SSD will work in this mode. It is not recommended to run SSD's in RAID mode. I am unable to determine if your BIOS supports RAID or if the default BIOS setting is set to RAID or IDE mode. Check with SSD manufacturer to verify the SSD will run on SATA1 and SATA2 ports. I am unsure what SATA specification your motherboard supports. Cheers!

I don't think XP will boot in AHCI, but 7 will;  so if you want AHCI, you'll have to forego booting in XP, and I'm not sure you can even boot at all, except in ATA, if XP is first in the boot list, and AHCI is off.  XP can only boot in ATA, at least on the i5 machines I newly installed it to (32-bit, Pro).  Maybe someone else has a better answer, but I see no alternative to what you're doing now.
