Memory Managers with Card and Socket Services A-3
In addition, Card Services needs at least 4 KB excluded
for its use. Remember, if you are using more than one
3C389 PC Card, the memory locations for the other
3C389 PC Cards must also be excluded.
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 3C389 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 card services, the /MA is used to specify the
range of memory the 3C389 PC Cards and Card Services
use. The parameter is added to the Resource Map Utility
line in your CONFIG.SYS. For example:
■ Using IBM Card Services:
On a PC 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 PCs. Consult your notebook
user guide.
■ 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 3C389 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
notebook user guide for the version you have and
whether the /ADDR option is needed.
The /ADDR parameter needs only the starting address of
the Card Services memory area.
