How to UPGRADE from Vista to Windows XP on an Acer laptop

Step 5Fixing AHCI

Fixing AHCI
Everything working OK now? No exclamation marks or unknown hardware? Great! Now let's conquer the AHCI issue. On the driver CD, browse (don't auto-run) to the Drivers\ directory. Copy the AHCI folder to your C: drive, so now it's c:\AHCI\. Open the command line (Start -> Run -> cmd), and enter "c:\AHCI\setup.exe -a -pc:\" (without the quotes). This will pop up the setup utility. Click through it- it's not actually installing, but extracting the drivers for us to use. You'll find them afterwards in C:\Driver.

Now we manually install the driver into XP: Go to Device Manager, under IDE ATA/ATAPI controllers you should see something like: ICH8M SATA Controller. Right-Click on that and select Update Driver. Choose No to connecting to Windows Update to search, then hit Next. Select Install from a list or specific location (Advanced), hit Next, then select "Don't search. I will choose the driver to install." Hit Next again, then select Have Disk. Browse to your Drivers folder (C:\Driver), highlight the iastor.inf file, and hit Open. Select OK, then choose your AHCI driver (what we wrote down earlier, remember?). You'll likely have to uncheck the 'show compatible hardware' option to see the AHCI options. Again, on the Extensa 5620-6830, it's the Intel 82801HEM/HBM SATA AHCI Storage Controller- YMMV (Your Motherboard May Vary). Click next, ignore the warning that installing the device driver is not recommended, click Yes, Finish, then Yes to restart your computer.

if i can reply to my own post! i think this was because i had changed the hdd to ide and there was some residual thing going on from achi. anyway, in the end, i just rebooted the computer and everything went fine.
