The information in this article applies to:

Microsoft Windows versions 1.x, 3.0, 3.0a, 3.1, 3.11

SUMMARY

This article discusses switch settings for the IBM Token-Ring Network PC Adapter.

The following are switch-configurable parameters for the Token Ring adapter and conflicts that may occur:

The Interrupt Line address may conflict with devices such as the Microsoft Bus Mouse, hard drive controllers, serial and parallel ports.

The Base I/O address may conflict with expanded memory boards.

The Memory Map Address may conflict with the memory addresses used by expanded memory board drivers, 3270 cards, ESDI hard-drive controllers, and display adapters.

It may be necessary to change switch settings on the Token Ring Adapter and/or other cards in the system to avoid such conflicts.
