DOS Compatibility Card: How to Access Upper Memory (5/96)

The DOS Compatibility card supports upper memory. To access upper memory make the following change to your config.sys file:

If you are using PC Setup 1.0.7, the lines are:

DEVICE=C:\\DOS\\EMM386.EXE NOEMS X=C800-CFFF RAM=D000-EFFF

or

DEVICE=C:\\DOS\\EMM386.EXE X=C800-CFFF RAM=D000-EFFF

For PC Setup 1.5, the command lines are:

DEVICE=C:\\DOS\\EMM386.EXE NOEMS I=CA00-CBFF X=CC00-CFFF RAM=D000-EFFF

or

DEVICE=C:\\DOS\\EMM386.EXE I=CA00-CBFF X=CC00-CFFF RAM=D000-EFFF

Depending on how you have configured the file, config.sys should look similar this:

DEVICE=C:\\DOS\\SETVER.EXE
DEVICE=C:\\DOS\\HIMEM.SYS /TESTMEM:OFF
DEVICE=C:\\DOS\\EMM386.EXE X=C800-CFFF RAM=D000-EFFF
DOS=HIGH,UMB
FILES=30
LASTDRIVE=M

This information is also provided in the DOS Compatibility Card Read Me File.
