Hi Charles,

You should use other fdisk programs or, even better, use another
operating system for the fdisk step. That also lowers the risk
of damaging other operating systems, and you get a more user
friendly user interface.

By the way, warning! If fdisk CAN access the drive, but gets a
read error, it might reinitialize the MBR and flush the whole
partition table in an attempt to fix that. The other versions
spfdisk and xfdisk do not have that problem.

I did not know about that option, but it might mean that the LBA
support (disks above 8 GB) in your SCSI BIOS is flawed. Linux
does not need the BIOS after booting, so it is not affected.

Some other user recently reported that EMM386 caused crashes while
his AHA2940 was plugged, so you should try without EMM386. Possibly
also without the caches.

What other options are there?

> Extended BIOS Translation For DOS Drives > 1GByte = Enabled
> BIOS Support For More Than 2 Drives (MS-DOS 5.0 and above) = Enabled

Not sure what those mean, but you could try some other settings.
As said above, FreeDOS supports LBA, so you do not need CHS
translation modes as long as LBA works.
