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.
Note:
If the PC Card device driver is the PC Card point enabler,
you cannot use the PC Card with ThinkPad PC Card
|
support software. If you cannot set up the PC Card with
|
PC Card support software, check with the card vendor
whether the device driver is a client device driver or a
point enabler.
Power Management
Depending on the function of the PC Card, changing from one power
management mode to another might cause your ThinkPad computer
to hang. PC Card support software prevents this occurrence through
special handling during power state transition.
The following table approximately indicates the supported power
management function depending on the type of PC Card. If you
need a power management function, make sure that your PC Card
supports the function.
