Ok..got farther..or at least I know what to use in Basilisk II GUI..

sungem_eth.device.

No networking on the Mac side yet..still tryin to figure it out.

Update:

Under Linux, booting from the ISO of 8.1 just works. MorphOS, didnt. So I created a new Mac OS 8.1 hardfile and installed 8.1 fresh, copied over to MorphOS, disabled the Rose extension and booted up.
I installed OpenTransport 1.1.2, configured IP's manually..no ethernet yet.
