uses.
Memory Managers with Card and Socket Services
1. To prevent duplicate use of a memory location, the area used by your PC Card
must be excluded from the memory manager. To do this, you must edit your
CONFIG.SYS file. In certain environments, the installation program will add the
exclude statement automatically.
If you are in enhanced mode, 8 KB of the MMIO range must be excluded.
If you are in compatibility mode, 8 KB of the MMIO range (MMIO base address
default of D000) and 16 KB of the Shared RAM (SRAM) range (SRAM base
address default of D800) must be excluded.
In addition, Card Services needs at least 4 KB excluded for its use. Remember,
if you are using more than one PC Card, the memory locations for the other PC
Cards must also be excluded.
2. Card Services and memory managers typically do not talk to each other. You
must tell them what areas can be used. For example, with IBM Card Services
the /MA option is used to tell Card Services what memory range it can use for
PC Cards. It also uses some of this area for itself. That same /MA range must
be excluded from the memory manager line. This will prohibit the memory
manager from also using that same space.
For IBM CS, the /MA is used to specify the range of memory the PC Cards and
Card Services use. The parameter is added to the Resource Map Utility line in
your CONFIG.SYS. For example:
v
Using IBM Card Services:
On a computer using memory range C0000–CFFFF
DEVICE=C:\DOS\EMM386.EXE NOEMS X=C000-CFFF
.
.
DEVICE=C:\DOS\DICRMU02.SYS /MA=C000-CFFF
The Resource Map Utility driver name may be slightly different for the various
computers. Consult your operating manual.
v
Using Phoenix Card Services with the /ADDR option:
For some versions of Phoenix Card Services, the /ADDR parameter is used
to specify the 4-KB memory range used by Card Services. The memory
range chosen for the PC Cards must not conflict with this range. The /ADDR
parameter is placed on the Phoenix device driver line in the CONFIG.SYS
file. Consult your operation manual as to the version you have and whether
the /ADDR option is needed.
Note: The /ADDR needs only the starting address of the Card Services
memory area.
On a computer using memory range D0000–DFFFF
