Software Considerations for Windows
If you are using Windows, specify the memory area for Windows so
it does not conflict with the memory area for the PCMCIA device
drivers. After completing the installation for Windows, update your
SYSTEM.INI file as follows:
1. Open your CONFIG.SYS file using a text editor.
2. Find:
DEVICE= [drive:][path] DICRMU 1.SYS /MA=mmmm-mmmm
3. Note the address range of the PCMCIA device drivers
( mmmm-mmmm ); then close the CONFIG.SYS file and open
the SYSTEM.INI file of Windows.
4. Add the following line to the [386Enh] section of the
SYSTEM.INI file:
EMMEXCLUDE=mmmm-mmmm
The parameters for “/MA” and “EMMEXCLUDE” must be the
same.
5. Close the SYSTEM.INI file.
