IIRC, the board's "BIOS" (firmware) announced itself (i.e.
a banner typical of most adaptec controllers on bootstrap)
and then just hung -- as if the controller was probing
the SCSI bus and waiting for replies from (nonexistent)
devices on that bus.
So, it looks like the VW's firmware at least transfers control
*to* the card's BIOS to some extent. But, perhaps doesn't
have the right framework in place for the card and it to
coordinate their activities? I don't care if I can't *boot*
from a SCSI device. But, I would like for the bootstrap
PROCESS to continue and let Windows decide to recognize
the card or not...
I.e. I could understand if the VW's firmware had something
in it's PCI enumeration algorithm that just refused to talk
to anything that it didn't recognize ("support").
More to the point: does the VW place any other restrictions
(aside from 3.3V which the PCI connectors mechanically "enforce")
on the choice of cards that I can stuff in the box?
