#Expanded Memory
2 messages in this thread
I'm having trouble with my config.sys file. I have a 486SX25 PC, 4MB Ram, 124MB
hard drive,ISA/AT/Classic Bus, 640K of conventioal memory, 3072K of extended
memory,SVGA, Pro Audio Spectrum 16 Sound card, also MS-DOS 5.0. I installed a
Sony CD-ROM and it came with a CD game called "MANTIS". The installation tells
me that I need at least 768K of expanded memory but when I change the line in
my config.sys file from "DEVICE=C:\WINDOWS\EMM386.EXE NOEMS" to
"DEVICE=C:\WINDOWS\EMM386.EXE ON 780" The game starts but re-boots my PC after
about 10 seconds. I don't think I have a IRQ or DMA conflict but I'll wait to
see what some CD-ROM users suggest. Thanks for any help.
P.S. I plan on calling MICROPROSE Software monday but just couldn't wait
because I've gotten some good suggestions from the CD-ROM forum before.
Thanks again. Karen Zimmerman
Karen, there's some helpful info on optimizing memory, etc. in file Laser3.txt
in Lib. #4 here. Since it was written primarily for DOS, just be sure to use
the C:\windows versions of himem.sys and emm386.exe. After trying to allocate
as much EMS memory as reasonably possible, try looking for software conflicts
as outlined; they do arise on a title-by-title basis. Also try running the
disk without Windows (unless it requires Windows) and with as much conventional
memory as you can free-up, at least 550K or more, to further isolate the
problem.
Good luck!
