ASCENTIA 950N DOES NOT RECOGNIZE AST PCMCIA TOKEN RING CARD


PROBLEM

The Ascentia 950N system may not recognize the AST PCMCIA Token Ring Card if 
the sound option is enabled.

If the Sound option under the Audio Options menu is set to Enable, the system 
(Cardsoft's CARDINFO utility) does not recognize any PCMCIA Token Ring 
Adapters.  For example, when Cardinfo is run, it will say;

Slot 0:
Card Type Unavailable
Manufacturer = "IBM"
Product Name = "TOKEN RING"


CAUSE

There is a conflict in the sound option's default base memory address 220h 
with the AST PCMCIA Token Ring Card.


SYSTEMS AFFECTED
AST PART NUMBER AND DESCRIPTION

501707-XXX      ASCENTIA 950N


SOLUTION

1. In CONFIG.SYS, change the exclude memory address statement 
from D400-D8FF to D000-DFFF.

2. In system Setup, Sound Option, select a Base Address from the following:

240h
260h
280h


Save the settings and exit.  Reboot the system.

Note:
Default Base Address 220h should not be used to avoid the conflict with the 
sound.
