ABSTRACT:
In a computer system with a host bus and an EISA bus, devices typically implemented on an EISA bus are instead implemented on a host bus. These devices are still accessed with EISA commands, however, and an EISA bus controller bridge between the host bus and EISA bus is disabled on such accesses by being made to think that the actual command being executed on the host bus is a local memory command. This permits the EISA device to respond to EISA I/O and memory operations directed at addresses that it would normally respond to when connected to the EISA bus.
