Have you tried connecting it to the network with a sniffer running to see
how it tries to load its boot image?

Well, from the looks of it, it has a typical 286 era bios with a network
boot rom as the second rom. The 839x series network controllers are very
common, and most everything supports them. Have you had a look at the
Etherboot project's website?
http://etherboot.sourceforge.net/ Version 4.6
and earlier supports 286 hardware. If the second rom is indeed a feature
rom for netbooting, you could simply replace it with one you create with
etherboot and a programmer.
