Yes, it's the HP Precision Bus (aka NIO). AFAIK it's mainly used in the
(very) old servers, like F10. I don't know what the current status of
is, but it used to be unsupported (no docu ?).

Yes. Although (regarding to www.openpa.net) something like a modified

SE stands for SingleEnded and reffers to how the SCSI device is connected
(signalling etc.). It's the "normal" SCSI (unlike LVD,
LowVoltageDifferential), used in SCSI-I and SCSI-II (narrow)

It's the signal send on the scsi bus to negotiate syncronous data
transfer (or asynchronous sent with a REQ/ACK) if they support it.

Perhaps s.o. can answer this question. AFAIK somebody is indeed writing
on it and has succeded to use the console port on the MUX.
