Considerations
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.
OS/2
For OS/2 Warp:
If you have formatted your drive using high-performance file
system (HPFS) and your system has more than 64 MB memory
installed, hibernation mode is not supported.
If the COM port does not work even though you have set it up
correctly with the ThinkPad Configuration program, do as
follows:
1. Open System Setup.
2. Select Hardware Manager.
3. Select a folder from the menu.
4. Select Properties.
5. In the default pull-down menu, select No Hardware
Detection. If it has already been selected, change the
setting.
6. Open the ThinkPad Configuration program.
7. Set the COM port as desired.
8. Restart the system.
