I've got an asus a7v133a MB and used to have an 80 pin shielded cable plugged into the primary ATA drive, which was also plugged into my maxtor ATA100 drive. I recently reloaded the OS (win2000) and because I didn't have the 80 pin cable, I used a 40 pin cable and had to plug it into the primary IDE plug on the MB. Having recently found the 80 pin, I tried plugging that into the drive and the ATA slot on the MB, and BIOS won't detect the drive. Is it because I installed the OS while the 40 pin was installed?? I thought I could just change cables at will, but apparently not. Thanks.
