My model is a Fifty-Five, model 9615 (Model 55)

sometimes referred to as a 9614,9615
When flashing, saw Intel 28F001BX-T


Built-in adapter (which I can't find a packet driver for) is the PS/ValuePoint ISA Ethernet Adapater (for: LSP V1.2x)
This appears to be:
Eduquest Eth Adapter
10bastT
10base2

60G0887
FRU 33G8170
driver distro is VPETHER.EXE (although no packet driver!)

Saw this online:
PS/Valuepoint ISA adapter is actually a D-link DE220 card with the 
IBM mark. It is a "bad" ne2000 clone (close but not completely 
compatible). Updated drivers can be downloaded from the D-link web 
site (www.dlink.com). By the way, the card is supported both by Win95 
and Linux.
