Charlie, the sResource directory contains 2 pointers:
The first, at 01, points to the so-called "Board sResource", which
identifies the card as a "DNI Ethernet Card" by Cabletron Systems
The second, at 80, points to a so-called "Functional sResource", which
gives the technical info about the board. The first item, at 01, is just
the sRscType, which says it's an Ethernet card.
The second item, at 02, is the sRscName, which just names the card.
The 3rd, at 0A, is important - it is the MinoeBaseOS, which is an offset
from Fs000000 to the hardware base (presumable the set of registers for the
card). It is 00000000, which means the hardware starts at Fs000000, where
"s" is the slot number. I don't know offhand, & Apple's docs don't mention
it, what the last item, at 80, means.

Surprisingly, the sRsc item for the Ethernet Address is missing. Perhaps
this is why you are having trouble.
