Installing WinXP with Intel AHCI drivers

by on Jul.18, 2009, under General Jazz

I was trying to load XPSP2 on an Acer Aspire 4810T. I downloaded the XP AHCI drivers from the Acer site and tried to load the AHCI drivers from the floppy. It refused to give me the AHCI options, only RAID drivers!

Looked around a bit on the floppy and figured that the drivers are there but it doesn’t show up during the install. Haven’t fully figured this out, but the TXTSETUP.OEM needs to be modifed. I modified it and got the AHCI drivers to load successfully from the floppy.

Here’s what you need to do.
1. Open TXTSETUP.OEM in Notepad or any other text editor.
2. Locate the line that says :
scsi = iaStor_ICH8MEICH9ME

3. Change it to read :
scsi = iaAHCI_ICH9MEM

Start the XP install again with F6 and now you will get the option to load the AHCI drivers.

Hoping this helps someone out there.
