Mary: Depite my abject admiration for your computer knowledge, I question the idea that a harddrive, no matter how large, cannot be partitioned - with Windows or a program such as Partition Magic - into chunks of readable size by the OS and/or BIOS. My understanding is (was?) that one way or another, a harddrive can be partitioned into chunks readable by the OS/BIOS. Please elucidate. YOU: "Jack - For you to be able to partition the hard drive into sizes equal or less than the BIOS limitation the BIOS must be able to recognize the entire drive. The BIOS limitation of 8.4 g means that the BIOS can't recognize any part of the drive past the 8.4 g, therefore you would not be able to access it to partition it. "If there is not a BIOS upgrade, you could also add a Promise hard drive controller, Ultra 100 or Ultra 66, that would support the faster speeds of the larger hard drives now."
