When you insert the PC Card into your ThinkPad computer:
The PC Card support software detects the card and reads the
information about it.
The PC Card support software searches for the corresponding
card service device driver.
The device driver requests the PC Card support software to
allocate such system resources as memory space, I/O port, and
IRQ. If these resources are available, the support software
recognizes the PC Card and you can use it.
If there is a resource conflict, you need to change either the
resources or the system configuration:
Either:
– Change the requested resources of the PC Card: You can
allocate the available resources by using each operating
system or PC Card support software function.
Or:
– Change the system configuration: You can change the
system configuration with your operating system or with the
ThinkPad Configuration program.
