Advanced Information for PC Cards
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 “Starting the Auto
Configurator Utility for OS/2 or Windows” on page 249.
If you are using modem cards, 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 Mwave modem.) There are error messages that the
I/O port address 3F8 or 2F8, or IRQ level 3 or 4, were not
allocated.
In this case use the ThinkPad Setup Utility in the ThinkPad
Features program to:
– For OS/2: Disable the devices using COM1 or COM2; then
restart the system.
– For DOS or Windows: Reserve COM2 for the PC Card, and
use COM1 for other integrated communication devices.
