I noticed some people asking about jumper settings for the WD8003 ethernet
card and in looking through my stuff, came across the following information
regarding the WD8003E and WD8003EBT.  I hope this is helpful to someone out
there.

== 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.  (Factory
                           setting is jumper removed, which
                           ensures correct operation in faster
 			   AT bus systems.)  This jumper is 
                           ignored in XT bus systems.

  W1             I/O Base  Selects the I/O Base Address
                  Address  (Up to 3 jumpers)

         3-4*,5-6*,9-10*   280 -- the factory setting
         5-6, 9-10         2A0
         3-4, 9-10         2C0
         9-10              2E0

         5-6, 7-8          320
         3-4, 7-8          340

  W2     1-2      IRQ7     Interrupt request level.
         3-4      IRQ6     Only one jumper may be installed at a
         5-6      IRQ5     time.
         7-8      IRQ4
         9-10*    IRQ3     (Factory setting is IRQ3)
         11-12    IRQ2

  W3     1-2*     AUI-     Ethernet type: pins all jumpered to
         3-4*     BNC      use J1 BNC connector for this Ethernet
         5-6*              cable (* - the factory setting).
         7-8*              Jumpers all removed to use J2 AUI
         9-10*             connector (thick Ethernet cable).
         11-12*

  W4     1-2    Ethernet   Jumper removed for thin Ethernet and
                Version    IEEE 802.3/Version 2 thick Ethernet
                           (the factory setting);  jumper in-
                           stalled for thick Ethernet Version 1.

  W5     1-2*    Segment   Selects thin Ethernet segment length:
                 Length    jumpered for IEEE 802.3 standard 185m
                           length (*-the factory setting); jumper
                           removed for 300m extended length.

I don't know if there is a difference  between the WD8003 and the WD8003E,
and if this information is helpful, I can finally feel that I have made a
contribution to the Linux effort (small though it is).  Later.
