I assume that the "cannot sync" is because it is running of off cdrom.

	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

You might want to try without parity (4). I don't remember if it is
needed for Sun's or not. Also, check the termination. With 7 on, you
don't want to use an external terminator. Termination problems can
show up in weird ways...

I'm stumped as to what switch 5 is. One thing that I heard from a
friend is that Sun's require the CD Drive to use 512 byte sectors, vs
the default of 2048. As I posted the other day, I am looking for a
CD-RW drive that supports this. I think the Yamaha CRW4416 supports
this. It does not seem like this is what switch 5 does though...

A) is certainly possible.
B) I think Solaris 2.6 should run on a SS2. You might want to check
Sun's web pages.
C) No, I don't think this is the case. I recently install Solaris 2.6
from a very old 1X (??) drive. It took a year and a day to finish, but
it work.

I use an Antares Wide SCSI-FWS/2 controller in my sparc here. That's
where I got the info from. The only other thing I can think of is that
the first boot-device example I gave you ended in " disk". Maybe
supplying " cdrom" at the end...

I can lend you one from work if you want. It will have to wait until
tomorrow though.

I don't think it external disks. Come to think of it, I was having
problems when I was trying to connect a wide disk with a wide to
narrow adapter. I'm not sure why this did not work.
