First of all, I would like to thank everyone who went out of their way to
help me solve this problem. Thank you all very much, you know who you are! :)

In my original post, I wrote that I had two CD-ROMs, SONY CDU-76S and
MATSHITA CR-532-B, and could not get them to boot on a SUN SPARCstation
1+, EEPROM Rev. 1.3.

Most of you suggested I should check for a 512KB transfer rate jumper or
find a CD-ROM which is known to support this standard.
Following up on this, I checked the CD-ROM FAQ at

I have taken the time to compile a list of CD-ROMs which were described as
being compatible with, and work across all Sun machines without any
modifications except closing a jumper where noted.

Before I proceed with the list, here is the solution:

I looked at the back of my CD-ROM and there was a jumper labeled "TOP" I
closed this jumper and did the following:

ok probe-scsi

[listing of devices, CD @ DEV0 TARGET6]

ok boot sd(0,6,2)

and the booting process went on it's merry way.

As some of you suggested I also tried

ok boot sd(3,6,2)

and it seemed to work fine as well, although I never
finished installing it with those parameters. I decided to go with
recommended parameters instead (0,6,2).

For the sake of convenience I included a list of CD-ROMs that should work
with all Suns:

Compaq SCSI-2 2x CD-ROM (OEM Panasonic CR-503B)
DEC RRD40, RRD42, RRD43, RRD45, RRD46 (RRD46 is OEM Toshiba XM-5701TA)
IBM SCSI-2 2x CD-ROM (OEM Panasonic CR-503B)
Laser Magnetic Storage International Company CM234
Matshita CR-532B
Panasonic CR-503B
Panasonic CD-506B
Pioneer 4.4x SCSI-2
Pioneer DRM600/DRM604X
Plextor 4x/6x/8x/10x/12x
Toshiba XM-5701TA
Yamaha CDR-400t (this is a CD-ROM burner)

Many of these models can be found at <>, ranging
anywhere from $20 to $60 USD.

Finally, many thanks to Mike Frisch <> for
his excellent CD-ROM FAQ resource.
