NE2000 Jumper Settings
This document is for the NE2000 Network Interface card (NIC)only. Due to the frequent success, use, and popularity of this NIC, we are providing the following information in event that original documentation is misplaced or otherwise unavailable.
Whether upon first time installation or if needing to change any settings to avoid conflicting with other hardware, use this handy chart.
Set interrupt level (IRQ), use jumper block labeled W12, W13, W14, W15.
Interrupt (IRQ) Jumper blocks
Levels W12 W13 W14 W15
2 ON OFF OFF OFF
3 OFF ON OFF OFF
4 OFF OFF ON OFF
5 OFF OFF OFF ON
Set base I/O address, use jumper blocks W9, W10, W11.
Jumper blocks
Port Address W9 W10 W11
300 ON ON ***
320 OFF ON ***
340 ON OFF ***
360 OFF OFF ***
***May leave unchanged.
NOTE: W11 jumper is not used for base I/O address or IRQ settings but is included as part of the W9-W11 block. Its purpose is for remote boot capability which at this time is not supported by NetWare Lite.
Connector Type
To select 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.
Referring to the edge of the NIC with the gold fingers which insert into the mother board expansion slot, we will call this the bottom. Jumpers W1-W8 have 3 pins each. The bottom 2 rows must be jumpered for BNC connector type. (this is default setting) For DIX connector type, jumper the top two rows. Notice, physical location of jumpers will correspond to the location of the connectors at the end of the NIC.
W16 jumper.
This jumper sits all by itself and helps to resolve some timing issues. With some machines using Chips and Technologies chipset their is a slight buss timing difference. Microcode for the NE2000 was modified to help compensate for the timing problem dependant on whether W16 is jumpered or not. This has not been substantiated as a problem with NetWare Lite. However if you suspect a timing problem and have the fore mentioned chipset, remove jumper from W16.
