Linux on > 1Gbyte disks.

I have a 2G disk that is partitioned using the "head translation" trick
so that DOS will see more than 1Gbyte.
Now, when I try to create a Linux partition on this disk, I get in
trouble - fdisk returns errors when reading teh partition table.
(something to the effect that the partition is larger than declared).

Any idea how to make it work ???

-thanks.

Assuming that you're using the Linux fdisk program, before
attempting to do ANYTHING with the partition table, go into the expert
menu ('x'), and use the c,h, and s options to change the geometry mapping
to match that used under DOS (see the dparam.com program uuencoded in
the SCSI-HOWTO)

If you want to boot the disk using LILO, you'll also have to make a
disktab entry with this information.

1. Adaptec 1542C with HD >1GByte

I have a friend with no access to the Net, so I'm posting this for
him:

He's running a 486/66 with 16MB memory, an Adaptec 1542C, and a
Quantum 2.4Gbyte SCSI drive.

His 1542C came with the old prom, that did not support disks above
1Gbyte.  Linux worked fine, and he installed it in the lower 1GB of
his disk successfully.

When he upgraded the prom to use >1Gb disks, Linux stopped working, in
fact, won't even install.  He can disable the extended access feature in the
1542C and everything works again.

Obviously, he can't afford to give up 1.4Gb of disk space just to use
Linux.

Can anyone help?  E-mail or followups here, I read them all....
