tlug: Sparc question

[Jonathan Byrne <jq@example.com>]

Any Sparc experts up burning the midnight oil tonight?  I'm kind of
stuck here with this Sparc 2 and I hope I can tap into some advice here.

The problem:

I have a bootable CD (install disk for Solaris 2.6) in an external
CD-ROM drive (non-Sun, old, but believed to work).   Sun boxes
apparently expect to find the CD at SCSI ID 6.  It's not working,
however.  The chain of events looks like this;

boot cdrom

Boot device: /sbsu/esp@example.com, 70000/sd@example.com,0:c     File and args:
SCSI device 6,0 is not  responding
Can't open boot device.

The DIP switches on the drive are set for SCSI ID 6.  But the plot
thickens.  Typing probe-scsi gets me this:

Target 1
  Unit 0  Removable  Read Only Device    TOSHIBA CD-ROM
XM-3401TA028301/28/93

Target 3
  Unit 0   Disk    SEAGATE ST11200N  SUN1.0595000085283Copyright (c)
Seagate All rights reserved 0000

Target 5
  Unit 0   Disk    SEAGATE ST1480   SUN04248628       Copyright (c) 1992
Seaate   All rights reserved 0000


The report for the disks is consistent with the drive jumpers (both are
internal disks), but the report for the CD-ROM drive is not.  Moreover,
no matter what I do to the CD-ROM drives DIP switches, probe-scsi
*always* reports it as above.  I opened up the CD-ROM drive to verify
that the DIP switch cable was actually connected (it was), so I'm kind
of at a loss here.

The DIP switches on the drive are as follows:

	Label
	-----
1	SCSI ID 1
2	SCSI ID 2
3	SCSI ID 4
4	PRTY
5	PRV/ALW
6	TEST
7	TERM


The switches that are set to ON are: 2,3,4,7.
Swtiches 5,6 are off (any idea what 5 is?)

The activity light on the CD-ROM drive does flash when probe-scsi is
run.

Any ideas on what I need to do to make this work (maybe I just need a
newer CD-ROM drive in SUN enclosure?) are appreciated.

Oh, one other thing: this CD-ROM drive is attached to the SS2 using a
cable that is narrow at the SS2 end and wide at the CD-ROM drive end.
Is there any problem with this?

Thanks in advance,

Jonathan
