example, the setup programs. For more information, refer to the
manuals supplied with your computer.
If your PC Card is enabled by a PC Card enabler, you can
change the resources assigned to the PC Card by changing the
parameters in the PC Card enabler, or you can change the
settings in the configuration file of the PC Card. For more
information, refer to the manuals supplied with your PC Card.
If you are using Auto Configurator to enable your PC Card, you
can change the resources assigned to the PC Card by using the
Auto Configurator. Make sure the resource is not used by other
devices and can be used by the PC Card and its application
program. For more information, see Using the Auto Configurator
Utility.
If you are using modem cards, you should know that some
modem cards use serial port COM1 or COM2 and do not have
the setup information for COM3 and COM4. These modem
cards cannot be enabled when other devices are using COM1
and COM2. (For example, as a default, COM1 is used by the
infrared device and COM2 is used by the ThinkPad Modem.)
Error messages are displayed to tell you that the I/O port
address 3F8 or 2F8, or IRQ level 3 or 4, were not allocated.
If this is the case, use the ThinkPad Setup Utility in the ThinkPad
Configuration program to disable the devices using COM1 or
COM2; then restart the system.
Avoiding PC Card Resource Conflicts
PC Card Director checks the resources for most devices used by the
system to avoid resource conflicts, but it does not recognize all
option devices used. Especially if you are using the docking station,
there is a possibility that the I/O port address or IRQ level might
conflict with the PC Card.
Check the status of the PC Card by using PC Card Director. If the
PC Card is set to “Ready,” the resources used for that PC Card are
displayed. Refer to the manuals supplied with the system or option
adapters to check that the resources for the devices in the system or
for the option adapters do not conflict with the resources for the IRQ
level, I/O port address, or memory window of the PC Card. If you
