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 179.
Card Information Structure
When you insert an ExpressCard™ into a slot, the computer 
attempts to determine the type of card and the resources it requires 
by reading its Card Information Structure (CIS). Sometimes the 
CIS contains enough information for you to use the card 
immediately.
