Hints and Limitations
WIN
3.1
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
memory usage occasionally.
*
If you have installed more than 256 MB of memory, check the
*
[386Enh]
section of the SYSTEM.INI file and do one of the
*
following:
*
– If the
PageOverCommit
line is in the file, make sure its value
*
is 3. (If it is not, change it to 3.)
*
– If the
PageOverCommit
line is not in the file, add
*
PageOverCommit=3
*
After you change or add the value, shut down Windows 3.1 and
*
power off the computer; then power it on again after 5 seconds.
*
For more information on the
PageOverCommit
value
*
Windows 3.1 manuals.
*
*
The
PageOverCommit
value could be 2 or 1.
