There should be a message telling either that termination is ON or OFF.

aic7xxx: Cables present (Int-50 YES, Ext-50 NO)
==> aic7xxx: eprom not present, brdctl_int=0xac, brdctl_ext=0x6c
==> aic7xxx: Termination ON
aic7xxx: BIOS enabled, IO Port 0xe400, IO Mem 0xfafd0000, IRQ 9
aic7xxx: Extended translation enabled.
aic7xxx: Single Channel, SCSI ID 7, 16/16 SCBs, QFull 16, QMask 0x1f
aic7xxx: Resetting channel A

On my system the auto termination on a AHA 2940 works correctly.  If
you have an external SCSI device connected and the termination is
still ON you should manually configure your SCSI host-adapter to
termination off.  I wonder that the above lines didn't appear in your
message log at all.  I used dmesg to display them.


I haven't lost my mind -- it's backed up on tape somewhere.
