The information in this article applies to:
- Microsoft Windows NT Server version 3.1,3.5,3.51,4.0
- Microsoft Windows NT Workstation version 3.1,3.5,3.51,4.0
- Microsoft Windows NT Advanced Server
-------------------------------------------------------------------------------
SYMPTOMS
========
When installing two IBM Token Ring network cards, the following event message
appears in Event Viewer:
Event ID: 5012, Source: IbmTok01, Type: Error
Description: The I/O base address supplied does not match jumpers on adapter.
CAUSE
=====
The IBM Token Ring network adapter driver, IBMTOK.SYS, is looking for specific
Primary and Secondary Base I/O addresses which must match the switches set on
the adapter (Switch 9).
RESOLUTION
==========
Configure the Base I/O ROM addresses and corresponding switches listed below on
the adapter for the following switch 9 positions:
Switch 9 Base I/O Address Base I/O Switches
(Position) (Size = 8K)
-------------------------------------------------------
Primary CC00 1, 4, 5 - up
(Switch 9 = up) 2, 3, 6 - down
Secondary DC00 1, 3, 4, 5 - up
(Switch 9 = down) 2, 6 - down
NOTE: Although the adapter supports other base I/O addresses, the IBM Token Ring
driver supplied with Windows NT only supports the addresses of CC00 and DC00. If
either of these addresses conflict with other installed base I/O addresses,
reconfigure other adapters in order to accommodate the required I/O base
addresses of the IBM Token Ring driver. This adapter reserves two separate
address ranges - One for base I/O and one for Shared RAM. Make sure that these
two address ranges do not overlap by using the WinMSD utility.
MORE INFORMATION
================
Dip-switch settings for the IBM Token Ring adapter are:
Switches 1-6 Base I/O ROM Address
Switches 7,8 Interrupt Level (valid interrupts are 2, 3, 6, 7)
For IRQ 2 Jumper, these switches are down.
Switches 9 Primary / Secondary adapter
Switches 10,11 Shared RAM Size 8K , 16K, 32K, 64K
For 8K shared memory, 10 and 11 are down;
for 16K shared memory, 10 is up and 11 is down.
Shared RAM size addresses are reserved as follows:
- Primary adapter (Switch 9 = up) starts at D0000.
- Secondary adapter (Switch 9 = down) starts at E0000.
Listed below is a Length and Size equivalency chart:
Length Size
------------------
0x2000 8K
0x4000 16K
0x8000 32K
0x10000 64K
Switches 12 4Mbs / 16Mbs network
For 4 MB, Jumper 12 is down.
