I successfully changed to AHCI after installing XP x64 SP1, but now I need to change it back to IDE because of some performance issues (freezing and stuttering) when copying files between two drives (Samsung F1 1TB and WD Raptor 150GB).

I assume I have to force install the IDE driver instead, but I can't figure out which one it is. I'm using a Asus P5Q Deluxe board with Intel ICH10R chipset.

Hi,
You mention 64bits.

It has been quite a while I last ran XP64 and cannot say for sure it uses same registry entries.
(( but, I doubt the procedure described applies to X64 ))

Just set it to IDE in the BIOS and all should be back to where it was (besides some REG entries and files that will not be used but are present on the hard disk ).

It´s the same, but some 32bit drivers would not work 100% on a 64bit system...

Hi.

I have an ICH8M sata controller and I was wondering is this guide applies to that one too. Specifically, those numbers in iaahci.inf -- changing "2821" to "2923" -- are those the right numbers for ICH8M too?

Thanks

[James_A]

You'll have to check the INF file, but
2821 = 82801 (ICH8R) SATA AHCI Controller
2923 = 82801IB/IR/IH (ICH9 Family) 4 port SATA AHCI Controller

I think you need to look for:-
2828 = 82801 (ICH8M) 3 port SATA Controller

.

[francisc1701]

I looked for 2828 in iaahci.inf and got 0 matches.
There is this line

PCI\VEN_8086&DEV_2829&CC_0106.DeviceDesc	= "Intel(R) ICH8M-E/M SATA AHCI Controller"

but as you can see it's 2829.

Here's what I did:
- I followed step 2 of this guide, only I replaced 2821 with 2828
- I followed step 3, only I modified it with data taken from Device Manager:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CriticalDeviceDatabase\pci#ven_8086&dev_2923&cc_0106] -- the part after the last backslash became pci#ven_8086&dev_2828&cc_0101
"Service"="iaStor"
"ClassGUID"="{4D36E96A-E325-11CE-BFC1-08002BE10318}"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor]
"Type"=dword:00000001
"Start"=dword:00000000
"Group"="SCSI miniport"
"ErrorControl"=dword:00000001
"ImagePath"="system32\\drivers\\iaStor.sys"
"tag"=dword:00000019
"DisplayName"="Intel AHCI Controller"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Parameters]
"queuePriorityEnable"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Enum]
"0"="PCI\\VEN_8086&DEV_2923&SUBSYS_B0051458&REV_02\\3&13c0b0c5&0&FA" -- this became "0"="PCI\\VEN_8086&DEV_2828&SUBSYS_30D8103C&REV_03\\3&B1BFB68&0&FA"
"Count"=dword:00000001
"NextInstance"=dword:00000001

- I saved the .reg file, added it to the registry and rebooted
- I enabled Sata native mode in my bios and rebooted again
The result was the same STOP error on a BSoD

Can someone please point out what I'm doing wrong?

[James_A]

I am not really an expert on this, but I do know you should not change the class (CC_nnnn)

from CC_0106 (= AHCI)
to CC_0101 (= IDE)

I can't advise you on the subsystem values as that is beyond me.

And, yes 2829 (and 282A) are also ICH8 mobile as well as 2828. But they should already be in the .INF

.

[francisc1701]

James_A, thanks for the tips. I changed 0101 to 0106 but still no joy. Anything else I could try?

Never mind, it's working now

Thanks to Linux I managed to get it to work.

Turns out it was 2829, Device Manager only reported 2828 because it was emulating an IDE controller. I enabled Sata native mode, booted Kubuntu 8.04 (installed alongside XP) and issued an

lspci -v -nn

command. Here's the relevant part of its output:

00:1f.1 IDE interface [0101]: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) IDE Controller [8086:2850] (rev 03) (prog-if 8a [Master SecP PriP])
		Subsystem: Hewlett-Packard Company Unknown device [103c:30d8]
		Flags: bus master, medium devsel, latency 0, IRQ 16
00:1f.2 SATA controller [0106]: Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) SATA AHCI Controller [8086:2829] (rev 03) (prog-if 01 [AHCI 1.0])
		Subsystem: Hewlett-Packard Company Unknown device [103c:30d8]
		Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 220

So I modified that registry file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CriticalDeviceDatabase\pci#ven_8086&dev_2829&cc_0106]
"Service"="iaStor"
"ClassGUID"="{4D36E96A-E325-11CE-BFC1-08002BE10318}"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor]
"Type"=dword:00000001
"Start"=dword:00000000
"Group"="SCSI miniport"
"ErrorControl"=dword:00000001
"ImagePath"="system32\\drivers\\iaStor.sys"
"tag"=dword:00000019
"DisplayName"="Intel AHCI Controller"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Parameters]
"queuePriorityEnable"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Enum]
"0"="PCI\\VEN_8086&DEV_2829&SUBSYS_30D8103C&REV_03\\3&B1BFB68&0&FA"
"Count"=dword:00000001
"NextInstance"=dword:00000001

I added it to the registry, rebooted, enabled Sata native mode again, and this time XP started without a glitch. The "Found new hardware" popped up. When it asked for the driver for the Ahci controller I pointed it to the folder containing iaahci.inf, etc. It was not necessary to modify iaahci.inf at all.

I hope someone finds this useful.

[James_A]

Certainly it's useful to me: I already have Ubuntu 8.04, just never thought to use it to solve a Windows chip ID problem.

That's going in my "on-site" toolbox right now. Thanks for the info.

How do I roll back to IDE by the way? AHCI is only giving me random BSOD so I want to get back to IDE without reinstalling. Thanks.

Just switch to IDE in the BIOS, Windows will then use Microsoft drivers for IDE mode.

doesn't work, I get BSOD

Normaly that should work. Try the Microsoft way like cdob says.

2. Preparing the drivers

Copy the file IASTOR.SYS to the Windows SYSTEM32/DRIVERS directory. Open the IAAHCI.INF with Notepad from the directory where you unpacked the drivers. Use CRTL-R and you should get a "replace" window. In the first input window you type "2821" and the second "2923", so you will replace all "2821" text to "2923", and click "Replace All". Save IAAHCI.INF over the original file.

Replace the line:

<font size="1">PCI\VEN_8086&DEV_2923&CC_0106.DeviceDesc	= "Intel(R) 82801HR/HH/HO SATA AHCI Controller"</font>

To:

<font size="1">PCI\VEN_8086&DEV_2923&CC_0106.DeviceDesc	= "Intel(R) ICH9 SATA AHCI Controller"</font>

Save the file under the same name, e.g. IAAHCI.INF and exit Notepad.

I did this step. I attached my iaahci.inf here

3. Creating Windows registry file

Now we create a registry file with Notepad and the following contence:CODEWindows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CriticalDeviceDatabase\pci#ven_8086&dev_2923&cc_0106]
"Service"="iaStor"
"ClassGUID"="{4D36E96A-E325-11CE-BFC1-08002BE10318}"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor]
"Type"=dword:00000001
"Start"=dword:00000000
"Group"="SCSI miniport"
"ErrorControl"=dword:00000001
"ImagePath"="system32\\drivers\\iaStor.sys"
"tag"=dword:00000019
"DisplayName"="Intel AHCI Controller"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Parameters]
"queuePriorityEnable"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Enum]
"0"="PCI\\VEN_8086&DEV_2923&SUBSYS_B0051458&REV_02\\3&13c0b0c5&0&FA"
"Count"=dword:00000001
"NextInstance"=dword:00000001
Save it as AHCI_ICH9.REG and run it after closing Notepad.

I did this file too and launched it.

And enabled AHCI in bios
But i still get that blue screen.
Can you help me to fix it?

I can't really help, have a X48 board which comes with a ICH9R (RAID+AHCI support by default). I use the same driver package for my unattended setup and everything works fine - but i have a divverent northbridge which supports ahci by default.

Try the following:
1) download the 32-bit Floppy Configuration Utility for Intel® Matrix Storage Manager, open the zip file and extract it to c:\tempdrv
2) open your device manager and open the properties for your controller. on the details tab you can get the VEN- and DEV-IDs we need. Your VEN-ID should be VEN_8086.
3) open iaAHCI.inf with notepad, press Ctrl+H, enter in the first field "DEV_2821" and in the second your own DEV-ID (e.g. DEV_3445), then click on "Replace all". Press Ctrl+S and then Alt+F4.
4) install the new driver using the device manager (update/install driver)

If this does not help, begin from scratch again but at step 3) enter "DEV_2922" instead of "DEV_2821" into the first field.

If this does not help too, try if the driver is working for your device:
1) do the steps above except 4) but now with "DEV_2821" again
2) open TXTSETUP.OEM with notepad, press Ctrl+H, enter in the first field "DEV_2821" and in the second your own DEV-ID (e.g. DEV_3445), then click on "Replace all". Press Ctrl+S and then Alt+F4.
3) copy the files iaStor.sys, iaAHCI.inf, iaahci.cat, TXTSETUP.OEM to a floppy.
4) boot from a windows setup cd, press F6 at the beginning and insert the floppy. continue the setup until you are asked to select a partition on which you want to install windows. at this point you can eject your setup cd and reboot your pc (reboot-switch is advised instead of ctrl+alt+del).

if you have sucessfully arrived the "select partition" thingy, you can reboot your pc, the driver is working then. If not, try steps above but now with "DEV_2922".

DEV_2821 is Intel ICH8R/DH/DO
DEV_2922 is Intel ICH9R/DH/DO
what is DEV_2923 ??

attached i've the latest modified drivers (replaced DEV_2821 with DEV_2923).
