Expanded Memory Specification - IBM Turbo 16/4 Token-Ring PC Card 2 User Manual

3. General Rules:
Expanded Memory Specification
Expanded memory specification (EMS) requires 64 KB (one page frame) of
contiguous memory. This may cause you to move your PC Card memory range.
With EMM386 you set the page frame base address using the FRAME= option on
the memory manager line in the CONFIG.SYS. If the FRAME= option is not used,
EMM386 will find the first 64-KB block of contiguous memory. For example:
1. Using a point enabler with the PC Card at D0000–DBFFF, the C0000–CFFFF
2. Using a point enabler with the PC Card at D0000–DBFFF, the C0000–CFFFF
3. Using IBM Card Services, you can set the /MA option such that a 64-KB block

IBM Card Services
a. The memory area used by PC Cards must fall within the range specified
by /MA.
b. The memory area used by Card Services itself (4 KB) must be included
in the /MA range.
c. All of the /MA range must be excluded from your memory manager line.
Phoenix Card Services
a. The memory used by Card Services starting at the /ADDR address and
the memory used by the PC Card should be excluded from the memory
manager line.
b. If the /ADDR line is not used, the driver will use the first available
address on a 4-KB boundary for Card Services. The memory manager
line must exclude this area and the PC Card memory area.
range is free for the EMS page. A sample enhanced mode memory manager
line in your CONFIG.SYS is:
DEVICE=C:\DOS\EMM386.EXE RAM 1024 X=D000-D1FF FRAME=C000
Note: The Token-Ring PC Card uses D0000–D1FFF for 8-KB MMIO. The
FRAME= parameter sets the base address of the EMS page frame (the
page frame uses C0000–CFFFF). So, no PC Cards should be set to use
memory in the range C0000–CFFFF.

line in your CONFIG.SYS is:
DEVICE=C:\DOS\EMM386.EXE RAM 1024 X=D000-D1FF
X=D800-DBFF FRAME=C000
Note: The Token-Ring PC Card uses D0000–D1FFF for 8-KB MMIO and
D8000–DBFFF for 16-KB SRAM. The FRAME= parameter sets the base
address of the EMS page frame (the page frame uses C0000–CFFFF).
So, no PC Cards should be set to use memory in the range
C0000–CFFFF.
