ExpressCard™ problems

ExpressCards™ include many types of devices, such as a removable hard disk, additional memory, or a pager.

Most ExpressCard problems occur during installation and setup of new cards. If you are having trouble getting one or more of these devices to work together, several sections in this chapter may apply.

Resource conflicts can cause problems when using ExpressCards. See “Resolving a hardware conflict” on page 156.

If your system does not have built-in drivers for your ExpressCard and the card did not come with an operating system driver, it may not work under the operating system. Contact the manufacturer of the ExpressCard for information about using the card under the operating system.
