Abstract
A system and method in accordance with the invention permits the full support of two ISA buses, a local ISA bus and a second ISA bus. To do so, upon receiving an access cycle, the cycle is directed to the second ISA bus. The second ISA bus is monitored for a signal event which indicates that an ISA device is claiming the cycle. If the signal event does not occur, the cycle is directed to the local ISA bus.
