ADD-IN BOARD WITH PROGRAMMABLE CONFIGURATION REGISTERS FOR PCI BUS COMPUTERS

摘要

An adapter or add-in card for using in a peripheral component interconnect (PCI) computer includes an universal module which couples the card to the PCI bus. The module includes a set of selectively programmable configuration registers which are loaded by a microprocessor on the adapter. A circuit arrangement on the module issues a command which inhibits the PCI processor from accessing the configuration registers until fully loaded.
