WESTERN DIGITAL "PLUS"-FAMILY LAN ADAPTER BOARDS JUMPER SETTINGS 5 April 1989 Each Western Digital LAN adapter board provides several parameters that are configured by setting appropriate jumpers on the board. The following tables summarize the jumper configurations for certain adapter boards. For more detailed information on any board, or for information on jumpers for an adapter board that is not listed here, refer to the Western Digital "User Installation Guide" that comes with the adapter board. NOTES REGARDING XT/AT BUS BOARDS: o Each "PLUS"-family LAN adapter board contains a RAM buffer of either 8 or 32 Kbytes that occupies PC memory space. The base address for this RAM memory is set by the software you use, not by jumpers on the board. o Current network software distributed by Western Digital uses a default RAM base address of D0000 (hex); some earlier software used a C4000 default base address. o EGA and VGA adapters also have memory that occupies this area and could conflict. D0000 is often a good RAM base address for users of EGA adapters; D4000 is often good for users of VGA adapters. o Other add-on boards may also introduce conflicts with this memory space. Other conflicts can occur with the I/O base address and interrupt request level, which are controlled by jumpers as described below. For a Micro Channel bus board, the RAM base address, I/O base address, boot ROM base address, and interrupt level are set by the system configuration procedure when the board is installed. Every software driver obtains this information automatically and adjusts its operation accordingly. "*" denotes the settings of jumpers installed at the factory. == EtherCard PLUS (WD8003E) == And == EtherCard PLUS With Boot ROM Socket (WD8003EBT) == JUMPER PIN FUNCTION SELECTED BLOCK NUMBERS NAME WHEN JUMPER IS INSTALLED ------ -------- ---- ---------------------------- W1 1-2 Zero Select zero wait states for optimized Wait operation in a 6MHz AT.
