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: 

   1. The Interrupt Line address may conflict with devices such as the
      Microsoft Bus Mouse, hard drive controllers, serial and parallel
      ports.
   2. The Base I/O address may conflict with expanded memory boards.
   3. 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.
