Chapter 4 Troubleshooting

This chapter describes the problems and corresponding solutions that
may occur when installing a PC Card.

Symptom

Solution

Windows does not
detect the PC Card when
installed.

Verify that the PC Card is properly
inserted into the PC Card slot.
Check whether the computer has a
Plug and Play BIOS.
Windows 98/ME/2000/XP might not
detect the PC Card if a previous
installation of the PC Card was
cancelled before it was finished.
Remove the previous driver, and redo
the installation again.

Driver fails to load

A resource conflict could exist.
For Windows 98/ME/2000/XP, use the

Device Manager

to resolve resource

conflicts.
Select

System

from the

Control Panel

, then

click on the

Device Manager

tab.

Device conflict on a Windows
system

A device conflict under Windows
98/ME/2000/XP may be related to
the PC Card.
For Windows 98/ME/2000/XP, use the
Computer properties to identify the
used I/O port addresses and IRQ
values.
If there is a device conflict, select
alternative settings for I/O Base Address    or
IRQ values. If you know which device
is conflicting with the PC Card, you have the
option of changing that device’s I/O
address or IRQ instead of changing the PC
Card.
