How to enable AHCI after XP installation *GUIDE*

I hope this hasn't been posted yet.

Well, I wanted to install XP in my 1720 and even though I tried to integrate the SATA AHCI driver to my XP SP2 Disc, I could never get the windows installation to detect my HD's.

Instead, I had to disable AHCI in the Bios and that allowed me to install XP.

After the XP installation, I followed this guide in order to enable AHCI once again:

This is the installation procedure needed to enable AHCI after XP has been installed:

I just tried this myself and it worked...

Now, the chipset in question (1720) is the ICH8M Mobile with a Device ID of

DEV_2829 or DEV_2828

So just replace all instances of the DEV_27C5 with DEV_2828 or DEV_2829

After following the guide, you can update the drivers using Intel's latest AHCI drivers.


Instructions:
1) Make sure AHCI is not enabled in your BIOS, otherwise this guide is pointless for you.
2) Back up your Windows folder and prepare a boot disk in case this guide fails!
3) Download 79im05ww.exe from http://www-307.ibm.com/pc/support/site.wss...ocid=MIGR-62909
4) Extract the file to C:\DRIVERS\WIN\SATA.
5) If you have the ICH7M southbridge, go to step 8.
5) Open C:\DRIVERS\WIN\SATA\PREPARE\IMSM_PRE.inf in Notepad.
6) Replace any instance of DEV_27C5 with the following, according to your southbridge:
ICH6R - DEV_2652
ICH6M - DEV_2653
ICH7R - DEV_27C1
ICH7DH - DEV_27C1
ICH7M - DEV_27C5
ICH8 Mobile - DEV_2828 or DEV_2829 (you can check for this value in the device manager, under IDE / ATA Atapi Controller)
7) Save the file and close Notepad.
8) Click Start, select Run.
9) In the Open field type C:\DRIVERS\WIN\SATA\PREPARE\INSTALL.CMD and click OK.
10) Restart your computer, and enable AHCI on in your BIOS Setup.
11) Start Windows XP or Windows 2000. The Found New Hardware wizard will start automatically.
12) If running Windows XP:

1. Click No, not this time then click Next.
2. Select Install from a list or specific location (Advanced), then click Next.
3. Select Search for the best driver in these locations.
4. Select Include this location in the search: and specify the path, C:\DRIVERS\WIN\SATA, and click Next

AFTER you have followed all of these instructions, you still have to install the intel matrix storage manager driver from intel to utilize ahci (the above instructions allow you to enable ahci in your bios, but you still need the driver to get full functionality). go to;

RAID/AHCI Software - Intel® Matrix Storage Manager
current version as of this post is; 7.8.0.1012, date 11/9/2007

if the above link for the intel matrix storage manager goes down, you can search for intel matrix storage manager on the intel site to find it.

install the intel matrix storage manager driver. done.

EDIT: Edited to include suggestions by MR. 00011 (Thanks BTW)

 

i think i've posted this at least twice, good to see it as a new thread, though. good idea, orion. the link in step #3 needs to be updated...

edit: better yet, here is the 79im05ww.exe file zipped. thought i would post it here as it's getting hard to find! you should just change #3 to download from 000111 below.
it needs to be extracted (to convert it from 79im05ww.zip to a .exe file), then executed to begin the self-extractor.

oh, and for an IFL-90 (for those of you who have the same computer/southbridge as i do) number six should read;

6) Replace any instance of DEV_27C5 with the following: DEV_2829

This is a great guide, thanks a bunch! I am helping my friend downgrade her 1420 to XP and this definitely was the trick!
