A SS1+ should be able to boot from the right CDROM. See:
http://www.de.netbsd.org/Documentation/bootcd.html#sparcimage
Also, cdrecord has some build in options for creating sun bootable
CDs. There are pre build ISO images, see:
http://www.de.netbsd.org/Changes/#iso1.6

And: Don't put that PeeCee penguin OS on this nice machine. See

I don't know for sure about the 3501, but the 3401 has two pairs
of pads labeld "0" and "1" at the rear of the drive. There is a 
litle trace between each pad of a pair. If you open this two
traces the drive switches to 512 byte blocks. If only one trace
is opened the drive uses the "SGI" or "Sun" mode. (Forgot which
pad pair chooses what firmware.)

What was the standard SCSI ID for CDROMs on Sun? 4? Or is 4 tape?
So this will only work when the CROM has the "right" id.

Yes. I think a Sun machine that old can not boot from 2048 byte 
block CDROMs.
