2.6.1Overview
The PCI1131 is a bridge between the PCI local bus and two PC Card sockets supporting both 16-
bit and 32-bit CardBus PC Cards, and is compliant with the PCI Local Bus Specification Revision
2.1 and PCMCIAs 1995 PCI Card Standard. The PCI 1131 PC Card interface recognizes and
identifies PC Cards installed at power-up, run-time, and switches protocols automatically to
accommodate 16-bit and 32-bit cards. Support for new 1 6-bit PC Card...
