APPENDIX F
Excluding Memory From Windows
When you install LAN Manager on an MS-DOS computer running
Microsoft Windows version 3.0 or above, the Setup program modifies
the configuration files for correct operation. However, if your computer
has a network adapter that uses shared random access memory (RAM),
you must manually modify SYSTEM.INI, the Windows configuration
file.
When you modify SYSTEM.INI, you must exclude the shared RAM
memory area from use by the Windows program. Examples of adapters
that use shared RAM include the following:
• Western Digital EtherCard PLUS or EtherCard PLUS/A
• IBM Token-Ring Network Computer Adapter (1, 2, or A)
• 3Com EtherLink II (3C503) and EtherLink 16 (3C507)
This appendix describes how your computer’s SYSTEM.INI file was
modified when you installed LAN Manager and how to manually
exclude a memory area from being used by the Windows program.
To determine whether your network adapter uses shared memory, refer
to that adapter’s manual, or contact the vendor.
The information in the sections that follow provides a guide to
configuring network adapters that use shared memory. This information
provides as much detail as possible, but it may not be complete. Always
treat your network adapter manual or vendor as the final authority.
