Many UltraATA controllers appear to Linux as SCSI controllers since 
that's what the BIOS says.  I had a Promise controller once and I had to 
tell the BIOS to boot off a SCSI disk if I wanted to boot from a disk 
plugged into the UltraATA controller.

It's probably supported.  Plug it in and look in dmesg for /dev/sda 
devices.  Do an fdisk /dev/sda and see if it sees your 80GB drive.

Your system should not have this limit.  If you're using LILO, you 
should switch to GRUB though.  GRUB is the default for Red Hat Linux 9 
so unless you changed it, you should be okay.
