Hi,

I'm having trouble getting my tape drive to work.
Here my setup:

A AMD Athlon 1Ghz with 512 MB RAM.
Plextor PX-W4824A Rev: 1.05
Toshiba DVD-rom
HP DDS-3 SCSI tape drive connected with a LSI scsi controller.

ALL worked fine on my old server (PII 400) with no cd-rw.

Here's some info:

Well, I managed to solve the problem.

I'm not sure howto when booting, but the following procedure works (after booting):

Any hints on howto solve this at boot time are welcome.
I suppose something with /etc/modules.conf
