For Windows 3.1:
If a memory shortage or memory error occurs, do as follows:
1. Unload any unnecessary drivers from the CONFIG.SYS file.
(For example, unload printer drivers if you do not use a
printer.)
2. Reconfigure the UMB (upper memory block) using the
DEVICEHIGH
statement.
3. Use the multiple configuration setup for DOS (refer to the
documents supplied with DOS).
Use the DOS command
command MEM /C
to review your DOS
