Ups - I've overread that you even powered down.
However since this is a DEC card you can also do a lot from SRM.

Theoretically every card should work.
I've using a fxp(4) based card in AS4100 plus PC164 and xl(4) based
in PC164.
I'm also running a tx(4) based in NoName, but these have broken support
for autoselect.
Card selection for alpha is only a problem if you want to netboot,
otherwise the same criteria exists as for other platforms.
