It depends to some extent on which motherboard you are running.
The Intel L440GX series, which is most of what we have here at FNAL
currently, allows to direct the BIOS I/O out one of the COM ports,
usually COM2. We have some clusters where we have hooked these
up to a console server and been able to access all the BIOS from there.
Intel has a very nice client to do this on the Windows side as well,
unfortunately it can only cover four nodes at once and they are not
planning to expand it.
It would in theory be possible to extend vacm (from VA Linux) to do
this but the last I talked to their developers they weren't
moving this way.
