A couple questions. Is this an internal or external drive? If internal, is it to be the only hard drive?
I just added an 80gb external drive to my 98 unit. Bios limitations prevented me from using an internal drive. USB drivers were necessary, but it does work without the newer version of USB. The FDISK utility that comes with 98 couldn't deal with the 80gb drive, under-reported the size. A newer version of FDISK is available. Don't have the link handy but do have the file if you need it. Instead of using straight DOS mode to partition it, used the FDISK utility in a DOS window. Worked well.
If the drive is an internal drive, your BIOS probably won't allow it. You'll be able to tell if your BIOS reports the size correctly. Mine didn't. If it's an external, you might be able to use it, even if windows has trouble with the size. You'd need to partition it into smaller sections, say 3 40gb partitions. Only way you can tell is if the new FDISK utility reports the right size when used in a DOS window.
Hope this helps.
