This is the normal entry for the KLESI-B, the native
VAXBI controller for the TU81. As long as you only
have one "drive 0" tape, you can replace "uq0" with
"mscp".

The AIE is a VAXBI module with the capability of supporting
both Ethernet and a TK50. Generally you see it supporting
only one. The "aie" is the base module. I don't remember
what the "bvp" part stands but there are two.
bvpssp - BVP Storage Systems Port - (tape controller)
bvpni - BVP Network Interconnect - (Ethernet)
The real module names for the AIE varients are:
DEBNT
DEBNK
DEBNA
DEBNI
As far as I know the the xxxNK was the only one to support
the TK50.

This is the normal entry for a KDB50. As long as you
only have one "drive 0" disk in the system you can
replace the "uq0" with "mscp".

The AIO is a VAXBI controller for the RD54. As far
as I know it is only used in the VAXstation 8000.

I don't remember what AIE, AIO and BVP stand for. As mentioned
earlier SSP is Storage Systems Port. You might find something
if go searching through to some of the system include files.
I'd suggest the /usr/include/vaxsysap and /usr/include/sys/errlog.h
as places to start. They might have buried in them somewhere
the true names of those acronyms.

If you don't have those devices, then you don't need
entries for them in the configuration file. I'm
guessing that you have a VAX 82xx or 83xx.
