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.
Why? Keep it jumpered for 512 byte blocks. Any Sun should boot
with that. You may need to update the OPB version to get it to boot
from the 2048 byte block mode.
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!
Ths suggests that the system is looking for 512 byte blocks.
Jumper it that way and go for the sure thing. Maybe later you can
download the firmware patch and boot from the 2048 byte blocks -- but
why bother when you have a drive which can handle the 512 byte blocks?
Good Luck,
DoN.
