By the way....since I see you have 2 SCSI drives installed.
One possibility is also to just "dd" the Debian Installer CD image directl=
y to one SCSI harddisc
and boot from it. The parisc machines don't care if it's a physical CDROM =
or a SCSI (harddisc)
with an ISO image (you just have to mount it afterwards manually as /cdrom=
 during the debian
install steps).
