Hello all,

I have an Ultra 30 and have the same problem with two different CDROM
drives. At the ok prompt, I type boot cdrom. I see the message "Boot
device: /pci@1f,4000/scsi@3/disk@6,0 [...]" but the machine hangs. I
have to physically reset it. A probe-scsi reveals that the drive is
detected and at Target 6... Any ideas?

Thanks,
- Alex

Where did the CD-ROM itself come from? IME, Suns are not keen to boot from "home
made" ones.

To be fair, I've tried this most recently with a Toshiba XM-4101
pulled from a Sun 411 enclosure. However, I had initially tried with
a 32x Teac that admittedly had no connection with Sun.

The other thing that doesn't add up is that the Teac works as a boot
drive for my Sparcstation 20. I'm starting to wonder if there's
something wrong with the Ultra 30's SCSI controller. If this is true,
it's odd that probe-scsi has no trouble finding everything on the bus.

I realize that I may have misunderstood your question. The CD-ROM is
always a CD-R with Solaris or NetBSD. Note that I'm able to boot
using a CD-R on the SS20 without too much difficulty.

These are SCSI CD-ROM drives? (I don't know the Ultra 30). And
are you booting a CD-ROM or a DVD-ROM?

The SCSI DVD-ROM reader which shipped with the Ultra-2,
Ultra-60, and SB-[12]000 and Sun Fire 280R (and probably other systems)
are typically the TOSHIBA SD-M1401, and if the firmware is not recent
enough, it won't boot from DVD-ROMs, but will boot happily from CD-ROMs.
Once you have the system booted, it will happily read DVD-ROMS as well
as CD-ROMs.

The required firmware level is 1009, which IIRC shows up run
against the M1401 from probe-scsi-all. If you have an older version,
then you need to download the firmware patch from Sun. It is called:

111649-04.jar

though you may find it more easily without the '.jar' in the search for
the right patch.

Hmm ... the FEH shows two possible CD-ROM drives, but no DVD-ROM
drives. They are the 370-2816 and 370-3415. If your drive is not one
of these from Sun, you may have a different problem. Most CD-ROM drives
have default sector size of 1024 bytes (or is it 2048 bytes?), while
older Suns need a drive which defaults to 512 byte sectors to boot. I
would think that the Ultra-30 should be late enough to have a OBP which
can command the drive to 512 byte/sector mode for booting.

Good Luck,
DoN.

The disk, not the drive. Where did the *disk* come from? Did you burn it
yourself or is it a proper Sun one?

Hi Don,

Yes, it's all SCSI on the Ultra 30. (One of the reasons that I bought
it and not an ATA model although I'm now starting to wonder!)

By default, the Teac drive does the "modern" block size but has a
jumper for the 512b mode. I'm trying to make it boot in 2048b mode
with a burnt CD-R of Solaris 10.

The odd thing is that if I substitute this CD-R for another CD-R of
NetBSD for Sparc-32 and put the 512b jumper, the machine starts to
boot the disque until the NetBSD setup realizes that this is for the
wrong architecture!

Yeah I realized that and tried to rectify in the above and below
posts. All CDs are CD-Rs of either Solaris or NetBSD.

So how many times does Huge have to ask the question before you answer
it...?
