I'm a bit confused by this thread. I have two PDC2067 chips in my
fileserver, both on Ultra100 boards and connected to 4 x 30Gb IBM deskstar
disks. I have it set up as one 15GB and one ~75Gb partition using Linux
RAID 5, and it works fine (as far as I can tell) with this config.

I do admit I have a fifth disk that has /bin, /etc, /boot on it for the
purposes of booting, so I can boot single user and maintain the RAID array
when necessary.

Is the issue here about the Promise FastTrack BIOS messing things up? If
so, why use it, rather than the Promise Ultra100 BIOS, which seems to be
fine (again, AFAIK).

Yours,

Ruth
