I found on Maxtor site another set of cylinder limitation settings that I had not seen. They allowed me to boot into 98 start disk and see the drive using fdisk. It only recognized 6150 mb.

You don't have to be able to boot to the hard drive to update the bios. You can take the hard drive out to update the bios if you want. If you can boot to a floppy then you should be able to update the bios. Most bios updates are done from floppy. Get the bios update from the motherboard manufacturer and most likely it will be done from floppy. Hope this helps.
