This could be the debug monitor firmware. I think this is the firmware
originally shipped with the evaluation boards and it's quite useful
for OS development.

IIRC the *dbm.rom image is the actually rom image, while *dbm.cmp can
be loaded and started by a different firmware (i.e., is
relocatable). For example, I once loaded the dbm cmp image via
ALPHABios to test the image and flashed the dbm rom image.

This is probably of no use for NetBSD since the debug monitor doesn't
contain the OSF PAL code.
