Looks like the 'DISKLESS' kernel has "helpfully" been stripped down...
but the stripping included the ie* network interfaces. To be fair just
about all DISKLESS boxes were 3/50, 3/60 and similar le* equipped
machines, but its not much help for a 3/110 :)
a) Quick option - try a GENERIC kernel instead of DISKLESS
b) More involved option - download NetBSD source tree to your mac
under OS X, copy the ie* lines from sys/arch/sun3/conf/GENERIC to
sys/arch/sun3/conf/DISKLESS, run './build.sh -m sun3 tools' and
'./build.sh -m sun3 kernel=DISKLESS'
As NetBSD on this box is a means-to-a-SunOS-end, I'd suggest a) :)
