I thought I finally had figured this out... I integrated the Gigabyte Jmicron Drivers into my XP installation disk and it recognized the drive, installed Windows and started to boot but git a BAD_POOL_CALLER error just before getting into Windows. I could boot into Safe Mode, and I'm assuming its related to the AHCI drivers. The problem is I don't have a floppy drive but I want to use AHCI on my HDD (Not RAID though). My motherboard is a Gigabyte 965P-DS3P, and it also has IHC8R SATA controller, but I couldn't seem to extract the .inf files from the installation package! I had a choice of TXT mode drivers from a floppy folder, PNP drivers from a drivers folder and some application driver as well... the first time I tried it with just the AHCI driver from the floppy folder, and selected the highest number (GBxxx), but it didn't recognize the HDD during installation, so I tried again and selected all the drivers for XP, and that's how I got to where I am now. I have read of other people doing this, so I know its possible, and I don't want to keep burning disks and installing XP with every possible combination, so I was wondering if anyone knows what I'm doing wrong? Thanks.
