IBM ValuePoint - Token Ring errors with SoundBlaster 16 installed
Applicable to: World-Wide
Symptom:
PS/ValuePoint systems (All Models) may experience system hang conditions or Token Ring initialization errors with an IBM Shared RAM Token Ring adapter and a Creative Labs SoundBlaster 16 adapter installed. IBM Shared RAM Token Ring
Adapters include the:
IBM Token Ring Adapter - Long card (FRU P/N83X9147)
IBM Token Ring Adapter II - Short 8 Bit Card (FRU P/N16F0463)
IBM 16/4 Token Ring Adapter - Short 8 Bit Card (FRU P/N93F0334)
IBM 16/4 ISA-16 Token Ring Adapter - (FRU P/N73G2048)
Problem Isolation Aids:
If the SoundBlaster 16 adapter is set to I/O base address "220" and the IBM Token Ring adapter is set for "primary," an I/O address conflict exists which may cause the Token Ring adapter to fail to initialize or cause the system to hang.
The I/O base address for the IBM Shared RAM Token Ring adapters as well as many OEM Token Ring Adapters is A20. This I/O address is hard coded and cannot be changed unless the Token Ring adapter is switched from "primary" to "secondary."
The SoundBlaster 16 adapter defaults to I/O base address 220. When set at 220, the SoundBlaster 16 adapter will respond to I/O accesses intended for the Token Ring adapter. The result is an I/O conflict.
Fix:
Change the I/O base address of the SoundBlaster 16 card to something other than 220.
