BIOS files are not OS dependent, meaning just choose any OS and download the latest BIOS revision (A10) and then follow the instructions to making your floppy disk. These older dell update packages dont include a flash updating utility. They use an older method of creating a bootable floppy and then restarting your computer with the floppy inserted.
If you don't have a bootable floppy, then you will have to either make one in windows
or
use the UPPER file on
this page
I would just be safe and use a windows 98SE boot disk. It's fast and easy. Then you should be able to proceed to the next step
98 Boot Disk
an MS-DOS boot disk would be the easiest, but it's up to you
98 Boot disks are smaller, that is why I like them rather than the latest DOS boot disks (6.22)
See other bootable floppy downloads here
You don't need a special boot disk. Just something that you can copy a file to and then from from a dos prompt.
After you have created the floppy, copy the LOWER file from
this page to it... just like it says
After upgrading the BIOS to A10, reboot and one of two things should happen:
1) Your drive should read the entire amount or
2) You may have to go into Computer management and allocate the rest of the drive and format the remaining portion.
Either way though, as long as your bios reads it as the proper size, and you are running SP3 for Win2k or higher, you should be able to use drives larger than 130GB and have the entire thing read by windows.
