what u should do is go into the bios and look around in the main page
if u have your hdd pluged into the ata100 controller then nothing will show up there as an IDE hard drive
*ATA100 plug* - the stuff down below is for you if u plugged your hdd into ata100 slot, if not, READ the next paragraph
go to the boot page in your bios and look down at um...two options u should see
one is ata100/scsi boot sequence and the other is load onboard something bios, what u should choose is ata100/scsi for the first option and auto for the second option
after you get into windows u need to install the ata100 controller drivers and after u reboot, your hdd should be reconized
*IDE plug*
boot into bios then look at the main page, you should see four things in the middle of the screen
primary master and slave, secondary master and slave
choose auto for all of them and the bios should detect the hdd
*last thing*
if you are talking about seeing the GENERIC IDE DISK TYPE47 stuff, that's normal, if that's the case then you don't need to worry because this is normal for hdd, same thing goes for plugging the drive into the ata100 or regular ide controller
