Onboard termination of SCSI controller ?
I'm doing some work on an *old* (7011-250 I think) RS/6000 machine.
Can anyone hazard a guess at whether the onboard SCSI controller
termination will be effective when the machine is booted with the
keyswitch set to "LOCK" ?
I'm accessing the internal disk with an external machine (via the
external SCSI port), while the machine is booted in "LOCK", so the
internal disk is powered but the controller is inactive. (Don't ask
why, long story...).
Just wondering whether this means the internal controller end of the
SCSI bus would still be terminated or not...
Thanks in advance !

I seem to recall that a slightly intelligent (say, Adaptec 2940u) SCSI
controller, can tell whether the line is terminated or not (if you set
the internal termination of the Adaptec to fixed-on, it'll tell you if
the other end is terminated, not terminated or double terminated).
I haven't tried it recently, but something about this lingers somewhere
in deep memory, so I could be wrong with the make/model of the card.
