Troubleshooting Common Problems and Frequently Asked Questions This section provides: Common problems and their corresponding actions. Frequently asked questions and their answers. Common Problems and Actions Problems I cannot use PC Cards other than IBM ones in the OS/2 Warp environment. My computer does not show as good performance as I expected. Error 2xx appears (memory error). A memory shortage or memory error occurs. Actions If you do not have the PC Card device driver for OS/2 but you have one for DOS, your PC Card may run in the VDM (virtual DOS machine) environment. Refer to "Virtual Card Services" on page 194 for setting the VDM and the sample configuration files on the PCMCIA Installation Diskette for OS/2, Windows 95. (If the PCMCIA Installation Diskette for OS/2, Windows 95 did not come with the computer, create it using the Diskette Factory program.) Performance varies depending on your hardware and software configurations such as memory size, swapper file size, or smart drive settings. Make sure your memory card is correctly installed. (See page 89.) When you are using DOS, it is recommended that you use the DOS command MEM /C to review your DOS memory usage occasionally. And then: - Unload any unnecessary drivers from the CONFIG.SYS file. (For example, unload printer drivers if you do not use a printer.) - Reconfigure the UMB (upper memory block) using the DEVICEHIGH statement. - Use the multiple configuration setup for DOS (refer to the documents supplied with DOS). When you are using Windows Version 3.11: - Try the same actions as described for DOS. - Unload any unnecessary programs from the WIN.INI file (for example, FUELWIN for ac operations.) Chapter 8.

Common Problems and Actions
Problems
Actions
I cannot use PC Cards other than
IBM ones in the OS/2 Warp
environment.
If you do not have the PC Card device driver for OS/2 but you have one
for DOS, your PC Card may run in the VDM (virtual DOS machine)
environment.
Refer to “Virtual Card Services” on page
194 for setting the
VDM and the sample configuration files on the PCMCIA Installation
Diskette for OS/2, Windows 95.
(If the PCMCIA Installation Diskette for
OS/2, Windows 95 did not come with the computer, create it using the
Diskette Factory program.)
My computer does not show as
good performance as I expected.
Performance varies depending on your hardware and software
configurations such as memory size, swapper file size, or smart drive
settings.
Error 2
xx
appears (memory error).
Make sure your memory card is correctly installed.
(See page 89.)
A
memory shortage or memory
error
occurs.
When you are using DOS,
it is recommended that you use the DOS
command
MEM /C
to review your DOS memory usage occasionally.
And then:
–
Unload any unnecessary drivers from the CONFIG.SYS file.
(For
example, unload printer drivers if you do not use a printer.)
–
Reconfigure the UMB (upper memory block) using the
DEVICEHIGH
statement.
–
Use the multiple configuration setup for DOS (refer to the
documents supplied with DOS).
When you are using Windows Version 3.11:
–
Try the same actions as described for DOS.
–
Unload any unnecessary programs from the WIN.INI file (for
example, FUELWIN for ac operations.)
