The Ethernet drivers are supplied as part of Intel's OpenNET software package.

It is possible to up to 3MB of memory to the iSBC 286/10 CPU board.  There is
a 2MB board available called the 020CX and a 1MB board called the 010CX, both
use ancient 150ns DRAMs, and if your unlucky and get an old revision, it will
have 64K-bit DRAMs.  :-(  I would suggest upgrading to an iSBC 286/16 CPU board,
it would contain 4MB of RAM on a daughter-board and be significantly quicker.
Better yet, upgrade to a psuedo-320 with an iSBC 386/16.

As of this writing, there is no SVR3 available for the Intel 3xx Series that
I know of.  I am currently running Intel System V/386 on my Intel 320.  It is
a SVR2 conforment and supports a streams based version of OpenNET and RFS.
I do not belive this version of UNIX will run on Multibus I machines like the
Intel 310, only on Multibus II systems from Intel, like the 320.

I'm not sure what mode XENIX runs in, I do know the Intel 310 diagnostics
run in protrcted mode.
