PCI Configuration Registers

A.1.20 CardBus CIS Pointer (@ 28h)

This register is used by those devices that want to share silicon between Card- Bus and PCI. The field is used to point to the Card Information Structure (CIS) for the CardBus card. On ThunderLAN this register is hardwired to a value of 10000107h which indicates that the CIS information is in expansion ROM at image1 and offset 20.

For a detailed explanation of the CIS Pointer, refer to the 1995 PC Card Stan- dard Electrical Specification. The subject is covered under the heading CIS Pointer and describes the types of information provided and the organization of this information.
