That's possible, I suppose. That's relatively easy to test. You can
disable sync negotiation by either compiling with flags 0xff00 (I think)
or by setting sc->sc_minsync = 0 around line 297 of esp.c (where it's
set to 1000/sc->sc_freq).

Not a bad idea. SCSI termination and cable length is always important. ;-)

That's good to hear! You're quite welcome.
