Going to install Windows 7 pro upgrade today using vista64 for the validation or whatever and back when I built this rig last year I remember I had issues with installing Vista, or even XP Pro that I had trouble in the bios setting the AHCI up. I wont be doing raid, and am going to install Windows 7 on my WD 300g raptor (GLFS model). I just checked and its in IDE mode. So my question is, before I boot from my upgrade disc of 7 should I hop in the bios and set it to AHCI, or leave it as an IDE? I will be unplugging my two other drives (Seagate 200g barracudas) before I install 7 to my 300g raptor. Will Windows 7 install the necesary drivers
to enable AHCI or what. Sorry for the confusion on this. Running the SZ1G bios, and please dont ask me to upgrade the bios first as I'm very uncomfortable doing flashes for some reason. Will I see that much gain in performance from IDE to AHCI, or is that a moot question. I've done quite a bit of reading here on the Windows 7 forums, and apparently I wont even have to run my X58 disc to install the motherboard drivers. Everyone says Windows 7 will install the current (to them) ones during the install.
