NE2000 Ethernet Card Jumper Settings
I also have a genuine Novell NE2000 Ethernet card that I use at times. Again,
I keep losing the scrap page that has the jumper settings listed on it, so
here they are. This card has both BNC (thin Ethernet) and a AUI (thick Ethernet)
connectors on it.
I/O Base Address - W9 & W10
Note: W11 is not used for the base I/O address.
IRQ Selection - W12 to W15
Connector Type - W1 to W8
To select the connector type, use jumpers W1-W8. The selection of this connector type
depends on the use of thin Ethernet cable (BNC connector) or thick Ethernet cable (DIX
connector), sometimes referred to as twisted pair connection depending on cable hardware.
The bottom is referring to the edge of the network board with the gold fingers that insert
into the system-board expansion slot. Jumpers W1-W8 have three pins each. The bottom
two rows must be jumpered for BNC connector type (This is a default setting). For DIX
connector type, jumper the top two rows. Notice, the physical location of jumpers will
correspond to the location of the connectors at the end of the network board.
Remote Booting - W11
This jumper is used to select whether the card will remote boot the PC. I
haven't used it, and leave it in the Off position.
Timing Issues - W16
This jumper sits all by itself and helps to resolve some timing issues. With some machines
using Chips and Technologies chipset there is a slight bus-timing difference. Microcode for
the NE2000 was modified to help compensate for the timing problem dependent on whether
W16 is jumpered or not. This has not been documented as a problem with NetWare Lite.
However, if you suspect a timing problem and have the fore mentioned chipset, remove
jumper from W16.
