parameters. This is not difficult unless you use several PC Cards at different times,
in which case you need to make certain that what you specify does not conflict with
any other PC Cards installed in your computer.
Autoset Mode
Card and Socket Services turns out to be most helpful when you have a number of
PC Cards installed in your computer. If the installation program detects Card and
Socket Services in your computer, it will default to Autoset mode. Autoset mode
allows your LAN driver to negotiate with Card and Socket Services for memory
space and interrupts every time you switch on your computer. This helps to prevent
conflicts with other PC Cards that are installed in your computer; however, you will
not know exactly what memory addresses and interrupts you are using.
Using a Memory Manager in DOS Environments
If your computer comes with a memory manager preinstalled, or if you would like to
use one, you must configure your computer so that the memory manager does not
use the same memory as your PC Card. If you have more than one PC Card, you
must reserve the memory needed for all of them. One PC Card cannot use the
same memory ranges as another.
To determine whether or not your computer has a memory manager, edit your
CONFIG.SYS file and look for the memory manager driver name. For example,
when using EMM386, look for:
DEVICE=C:\DOS\EMM386.EXE ......
When using a memory manager, considerations for your PC Card environment
(Point Enabler or Card and Socket Services) are required. Listed here are
explanations for handling these environments with a memory manager. It is not
intended to be all-inclusive. To understand completely your memory manager and
your configuration files, refer to your computer’s operating system manual.
Memory Managers with Point Enablers
v
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, LANAID will add the exclude
statement automatically.
If you are using enhanced mode, 8 KB of memory must be excluded. If you are
using compatibility mode, 24 KB of memory must be excluded.
v
For the point enabler, the required exclusions are shown in the example below
(using EMM386, this is done using the X= parameter):
For enhanced mode:
DEVICE=C:\POINTTR.EXE SA RS=4 MMIO=D000 IRQ=9 SRAM=D000,4 WS=0
.

DEVICE=C:\DOS\HIMEM.SYS

DEVICE=C:\DOS\EMM386.EXE 1024 RAM X=D000-D1FF
For compatibility mode:
