Hello, I'm having a similar problem with an Acer ASE 700 ED630M desktop. It was working fine and then, DISK BOOT FAILURE. Port 00 no device detected. The system uses a Phoenix-Award Bios Cmos Set up Utility. Under which heading to go to in order to configure the ACHI to ATA? I think I've been through all of them and can't find it. I've tried to reload windows and tried another hard drive, still a no go. Thanks in advance! I got the info from Soma's post here:

If you want simple solution follow the steps
Step 1: Start Your PC.
Hit F2 at startup then you will be led to BIOS, in BIOS Setup, change SATA mode from AHCI to ATA and Save and Exit.
Step 2: Insert XP CD in CD/DVD Drive
While booting hit F12 and choose Boot from CD/DVD drive. Then follow the usual procedure to install XP.
Note : It should work for any laptop/pc. I did this for "Dell Inspiron 1525" Laptop

Configuration: Windows XP
Firefox 3.0.7
