Advanced Information for PC Cards
Note:
The procedure assumes that you
are using “EMS386.EXE” as an
EMS device driver.
The following example shows the procedure for memory allocation
when an adapter that requires 32KB of memory is installed (the
required-memory space of the adapter cards might vary from one
card to another).
1. Open your CONFIG.SYS file using a text editor.
2. Find the DEVICE statement containing “EMM386.EXE.”
3. Change the statement to:
DEVICE=C:\DOS\EMM386.EXE 1 24 FRAME=D
X=C
-C7FF
X=C8
-CFFF
4. Find:
DEVICE=C:\DICRMU 1.SYS
Note:
The memory range specified by the
“MA=” parameter must be the same
as or included in the memory range
specified by the “X=” parameter.
5. Change this statement to:
DEVICE=C:\DICRMU 1.SYS /MA=C8
-CFFF /IX=11
6. Save the changes in your CONFIG.SYS file; then restart the
system.
Interrupt request level 11 cannot be used by the PC Card. After you
complete these steps, the memory map will be as follows:
C000:0
C800:0
D000:0
D800:0
E000:0

Examples of Hardware Configurations
The following examples show memory allocations and notices for
using various PC Cards:
Using PC Cards and SCSI adapter installed in the Dock I:
– Modify your CONFIG.SYS file as follows:
:
DEVICE=C:\DOS\EMM386.EXE NOEMS X=C
-CFFF
:
DEVICE=C:\THINKPAD\DICRMU 1.SYS /MA=C
