I have a PCI Sata card which I want to use with a 320GB WD HDD. I want to use the PCI card to boot up my HDD and able to install Window XP. As I know, I need mod my bios. I don't know which tools should I use and the proper way to done it. I'm a beginner on modding bios. Can some one guide me? I got try find at VIA forum, but I seems unable to understand well how to done it and there are many version of the tools. And my PCI card is VIA VT6421A.
