I hadn't checked, or known about that, however this is what my
config file has in it, and if I read the comments correctly (and
the comments are correct), I think I did disable sync.
# Note the flags on the esp entries below, that work around
# deficiencies in the current driver:
# bits 0-7: disable disconnect/reselect for the corresponding target
# bits 8-15: disable synch negotiation for target [bit-8]
# Note: targets 4-7 have disconnect/reselect enabled on the premise
# that tape devices normally have one of these targets. Tape
# devices should be allowed to disconnect for the SCSI bus
# to operate acceptably.
# sun4c or sun4m SCSI - an NCR53c94 or equivalent behind
# specialized DMA glue
dma0 at sbus0 slot ? offset ? # on-board SCSI
esp0 at sbus0 slot ? offset ? flags 0xff0f # sun4c
Do I need to change something here, is this the wrong part of the
config file, or is it something else?
