The processor speed might decrease under the following conditions:
Use in a hot environment
High-powered processing that requires high-power consumption
This is not a defect.
A memory shortage or
memory error occurs.
For DOS:
1. Use the DOS command MEM/C to review your DOS memory usage
occasionally.
2. Unload any unnecessary drivers from the CONFIG.SYS file. (For
example, unload printer drivers if you do not use a printer.)
3. Reconfigure the UMB (upper memory block) using the DEVICEHIGH
statement.
4. Use the multiple configuration setup for DOS (refer to the documents
supplied with DOS).
For Windows 3.11:
1. Try the same actions as described for DOS.
2. Unload any unnecessary programs from the WIN.INI file (for example,
FUELWIN for ac operations.)
