Subject: To the gentleman and others wondering what CD-ROM's might work with DIGITAL systems, here is a list I came across today.

Just came across this nice chart of CD-ROMS that work with DIGITAL =
systems.
Hope it's usefull.
Inofficial and incomplete list of third party cdroms that work with =
DEC's.

This list is maintained by Dennis Grevenstein. email contact info is
"cdromlist@pcde.inka.de" You can find an up to date version of this =
document

I. Introduction
The question "what cdrom will work with my old DEC?" is heard often. The
problem is that non-x86 workstations and especially DEC's will normally =
need
special cdroms that support special features. Many vendors released =
their
own branded cdroms for their hardware. But you will have to pay much =
more
money to get a slow DEC branded cdrom for your workstation than for a =
fast
modern or a real cheap old standard cdrom drive. So here is some sort of =
an
answer for all who are looking for a third party cdrom for a DEC
workstation. If the list gets longer(I hope so), I may release a html
version.
II. Some general information.
As most Unix workstations, DEC's will need a cdrom that is capable of
reading 512 bytes/sector, but most PC style cdrom's can only read 2048
bytes/sector. Often there is a jumper to enable this mode. If not, the =
cdrom
must support the "MODE SELECT" command that is send by the PROM to =
enable
the 512 bytes/sector mode. But often, even if a cdrom supports all of =
the
above and can be used with other workstation platforms e.g. Sun and SGI, =
the
cdrom will not work with DEC hardware.
III. drives that are known to work.
I decided to differentiate between VAX, MIPS based DECstations and Alpha
based workstations because of some irregularities. The Alpha section is
pretty small right now and Alphas should be compatible with cdroms in =
the
VAX or DECstation section, but a general rule could be: If a drive is =
not
listed as working in your category, don't get it. Sometimes cdroms are
tested with more than one version of an OS. In these cases the oldest
version that was bootet or installed succesfully is listed.

III.2 DECstations
DECstations seem to be really tricky, especially if you want to install
Ultrix. Normally Ultrix/MIPS can only be installed using an original DEC
cdrom. Typically your DECstation will boot of a compatible cdrom, but =
the
install programm will crash. If it is not compatible with a DECstation =
the
boot will fail completely. I can't say much about NetBSD, but my DR-466 =
does
not work with NetBSD 1.4.1 at all, but works fine with NetBSD 1.5. Other
people said that some older Toshiba cdroms work with VAXen, but not with
DECstations.

Sony CDU-8012 Ultrix 4.2 and 4.5 DECstation 5000/260, 5000/150
Note: Sun OEM Version Model 411 DECstation 2100
The old Sun model 411 cdrom seems to be special. It can be used to =
install
Ultrix/RISC and it is sometimes even detected as a DEC RRD42. However, =
it is
not any cheaper than a DEC branded cdrom when bought used.

III.3 Alpha
There seems to be a special problem with older Plextor cdroms, even if =
they
work with VAXen. Be careful.

IV. Other resources
The Sun cdrom FAQ may be useful. It provides some general information,
allthough this FAQ does not care, if a cdrom works with DEC hardware.

V. thanks, suggestions and all the other things...
Many thanks to all who contributed to build up this list.
This list is by no means complete. So if you have ever used a non-DEC =
cdrom
that is not shown here with a DEC workstation, please send some =
information
to "cdromlist@pcde.inka.de". If you have other suggestions or complains,
feel free to mail them too.
