AST RESEARCH, INC. TECHNICAL BULLETIN #0802 01-04-93
=============================================================================
POWER EXEC MODEM SOFTWARE AND EMM386.EXE
PROBLEM: Communication software used for modems may experience problems
on the Power Exec if EMM386.EXE is used along with the Card
Configuration Utility (CCU.EXE) program, part number
910717-031 release 1.0. This currently occurs with all
versions of EMM386.
CAUSE: Both the EMM386 program and the CCU program load into memory
at the same D000h memory location. CCU.EXE takes two 16KB
memory windows; one at DC00h for PCMCIA common memory and one
at D800h for attribute memory. Also CCU will establish a
memory window at D000-D400h for network adapters which is
documented in the Power Exec User's Guide, part number
001492-001.
SYSTEMS
AFFECTED: All Power Exec systems.
SOLUTION: Exclude the D000h-DFFFh memory range in EMM386. This will
prevent EMM386.EXE from using this memory range and allow the
CCU program to use the memory range.
For example;
DEVICE=C:\EMM386.EXE X=D000-DFFF
For more information on EMM386 and the exclude switch, please
consult your MS-DOS manual. Make sure the appropriate files
are backed up before modifying this statement.
CAUTION: In no case will AST Research, Inc. be liable for damage to the
system or loss of data caused by improper or faulty
installation of this file.
