I should mention that i have played with the network boodisk some. A 
couple of things to keep in mind. In some cicumstances (that i cant 
recall now) you need 2 parts... the ethernet extention (nubus,LC, 
built-in) whatever. In addation there is a resource in the system 
file (ENET) i think that is the lower level driver. I have some nubus 
cards in some old II** models that wont access the card until the 
driver is installed into the system file. Its possible for this to be 
hacked in. But the one time i tried it ii dont remebr if it worked. 
However on the flip side later version of the MacOS didnt need 3rd 
party drivers for card that did previously. its a lot of resource-fu 
going on here.
