Hi,
I have a Digital Personal WorkStation 500au running DU4.0D. This machine
used to have a Yamaha 400t scsi CDR device attached, but that device has
developed some sort of terminal problem since it was switched off, and the
whole lot move across town. The power supply is dead (that can be fixed) but
also even when the device has power, I can't get it to poke out the cd
shelf. So it would appear that both the power supply and the CDR did not
like being switched off for a couple of days.
The workstation came with an IDE cdrom, vis - rz0 at scsi0 target 0 lun 0
(LID=0) _(TOSHIBA CD-ROM XM-6102B 1106). What I would like to do is replace
this with a CDR (ie a burner, which I had bougth from Compaq, with the idea
of relacing some of the CDROMs in the unix workstations with CDRs, the
burner is an IDE device). When I replaced one of the CDROMs with a CDR in
one of the workstations (not this one) and I found the CDR would not boot
from the Tru64 5.1B system CD (I'm not sure but I think I duplicated the
master/slave setting of the CDROM), so I swapped it back out. However, for
the machine in question, once I have updated the current firmware and
upgraded the OS to 5.1B, I probably wont have any further requirement to use
the CDROM as a boot device.
The software that accessed the Yamaha comes from gear, and it is designed to
talk to scsi devices. The CDROM, is ide but it is made to look like scsi (by
some sort of protocol conversion, I guess) to the workstation. So I was
wondering if anyone has any experience in replacing their CDROM with a CDR,
and if so how successful were you.
