Advanced Information for PC Cards
DOS
Releasing the PCMCIA Memory Area
Note:
These procedures do not apply to
the device drivers supplied with your
PC Card.
If you are using DOS 7.0 or later but not are using the PC Card,
you can use the PCMCIA memory area as your application program
memory area. There are two ways to make this available for
application programs:
Use the PCMCIAOF command.
Use the DOS Multiple Configuration Function.
Using the PCMCIAOF command:
Type PCMCIAOF at the
command prompt (usually C:>). This converts the PCMCIA
DEVICE statements to comments.
The CONFIG.SYS file will look like this:
DEVICE=C:\DOS\EMM386.EXE 1 24 frame=D X=C8 -CFFF
:
REM DEVICE=C:\THINKPAD\IBMDSS 1.SYS /D
REM DEVICE=C:\THINKPAD\IBMDOSCS.SYS
REM DEVICE=C:\THINKPAD\DICRMU 1.SYS /MA=C8 -CFFF
REM DEVICE=C:\THINKPAD\$ICPMDOS.SYS
REM DEVICE=C:\THINKPAD\AUTODRV.SYS C:\THINKPAD\AUTODRV.INI
REM DEVICE=C:\THINKPAD\DISKDRV.SYS
DEVICE=C:\DOS\POWER.EXE
:
DEVICE=PC_Card_Client_device_driver
If you want to reset the PCMCIA memory area so you can use a PC
Card, enter PCMCIAON at the command prompt.
