From: schenk@cgull.ccsu.edu (Tom Schenk) Subject: WD8003E and WD8003EBT Jumper Settings Date: Wed, 14 Oct 1992 19:45:29 GMT
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
3-4, 5-6, 7-8 300
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.
== Additiional Jumpers On ==
== EtherCard PLUS With ROM Socket Only (WD8003EBT) ==
JUMPER PIN FUNCTION SELECTED
BLOCK NUMBERS NAME WHEN JUMPER IS INSTALLED
------ -------- ---- ----------------------------
W6 Open ROM C0000 (16K, 32K, 64K ROMs)
1-2 Base C4000 (16K ROMs)
3-4 Address C8000 (16K, 32K ROMs)
1-2, 3-4 CC000 (16K ROMs)
5-6 D0000 (16K, 32K, 64K ROMs)
1-2, 5-6 D4000 (16K ROMs)
3-4*, 5-6* D8000 (16K, 32K ROMs)--factory setting
1-2, 3-4, 5-6 DC000 (16K ROMs)
(NOTE: Do not use addresses C0000
or C4000 for Boot ROMs)
W6 7-8*,9-10* ROM ROM Disabled -- the factory setting
W9 3-4* Size "
W10 3-4* "
W6 Open ROM 16 Kbytes ROM
W9 3-4 Size "
W10 3-4 "
W6 7-8 ROM 32 Kbytes ROM
W9 3-4 Size "
W10 1-2 "
W6 9-10 ROM 64 Kbytes ROM
W9 1-2 Size "
W10 1-2 "
W7 3-4* RAM 8 Kbytes RAM -- the factory setting
W8 3-4* Buffer "
W11 2-3* Size " (NOTE: valid 8 Kbyte RAM base
addresses are C0000, C2000, C8000,
CA000, D0000, D2000, D8000 and DA000.)
W7 1-2 RAM 32 Kbytes RAM
W8 1-2 Buffer "
W11 1-2 Size " (NOTE: valid 32 Kbyte RAM
base addresses are C0000, C8000,
D0000 and D8000.)
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.
