NE2000 - Novell Ethernet interface card
---------------------------------------

- 16bit ISA-bus.
- Ethernet connectors: BNC, AUI.
- Some numbers on the board: "BD.#738-149-001 REV. F ASSY.#810-149-001 REV H"

(On=Jumpered, Off=Not Jumpered)

W1-W8: Select interface connector. It is not possible to use both connectors
  at the same time. ("lower row" = the row closest to the BNC connector)
 AUI - Connect each pin in the middle row with its corresponding pin in the
       upper row.
 BNC - Connect each pin in the middle row with its corresponding pin in the
       lower row.


W9,10: I/O Address.
       300h  320h  340h  360h
  W9   On    Off   On    Off
  W10  On    On    Off   Off


W11: Unknown. (Maybe for remote boot capability). Works both on or off for me.


W12-15: IRQ. Although the card has a 16-bit ISA connector it is NOT
  possible to select other (higher) IRQ's than these. (Note: see below)
  IRQ  W12  W13  W14  W15
   2   On   Off  Off  Off
   3   Off  On   Off  Off
   4   Off  Off  On   Off
   5   Off  Off  Off  On


W16: Default=Jumpered (On). Jumper can be removed if Chips And Technologies
  chipset is used and you suspect a timing problem.

===========================
Note: How to convert the card to use higher IRQ lines.
By "Ken". (shortened by me.)

With a bit of hardware hacking you can move IRQ 3 and 4 lines to IRQ 10 and 11.
IRQ 3 and 4 go to connector fingers B25 and B24 respectively. This is on the
copper side of the board. Counting back from the gap between the connectors,
they are the 7th and 8th fingers.

With an art knife or similar, cut the traces to the fingers.  Check
with an ohmmeter that the connection is indeed broken.

Get two short lengths of thin jumper wire and solder one end to the
trace that used to go to B25 and the other end to D3.  D3 is the third
finger counting from the gap. There should be no other traces ending at
D3. You can probably find a handy through hole for soldering the B25
end. On the D3 end it's a bit tricker. You need to solder to the gold
plated finger but use as little of it as possible so that any solder
bump doesn't interfere with the card going into the motherboard
connector. Do the same with the trace to B24 and finger D4.

Now the jumper for IRQ 3 selects IRQ 10 and that for IRQ 4 selects IRQ 11.
Put a sticker on the card explaining the new situation or you may forget.
===========================


To play network DOOM using the IPX protocol you need to load the following
files: (they are freely available at a lot of sites on Internet).

  LSL.COM
  NE2000.COM  (reads settings from NET.CFG)
  IPXODI.COM

You also need a text file NET.CFG containing the following lines:

LINK DRIVER NE2000
   INT 5
   PORT 300
   FRAME ETHERNET_802.3
   PROTOCOL IPX 0 ETHERNET_802.3

note: the "LINK" line must NOT be indented, the other lines MUST be indented.
Also, INT and PORT must correspond to the jumperings on the card.
