[comp.unix.questions] ra82 support in 4.3Bsd

jbh@etn-wlv.eaton.com (John B. Herbert) (05/06/89)

We are about to purchase a DEC ra82 for use on our VAX-750 running 4.3Bsd.
I have not been able to find any documentation on the 82 anywhere. My questions
are simple; 1) berkley has a ra series driver, what do I have to do, if anything
,
to make the ra82 work. 2) what are the slice sizes on the 82?

thanks in advance for the info.

(BSD calls them `partitions', not `slices'.)

All you need do is add size tables for the ra82 (and, if you boot off
the ra82, and you boot off other than partition `a', offset tables in
stand/uda.c).  (I assume the standard 4.3BSD driver distinguishes between
different kinds of RA disks---we never used it; we use my driver.)

You get to make up the sizes yourself.

Alternatively, switch to 4.3BSD-tahoe and put a disk label on the RA82.
