System for determining configuration of devices installed on a computer bus by comparing response time of data lines to read from I/O address when undriven

摘要: In a system that executes the method according to invention, each slot on bus is individually enabled at start-up and address of an range read determine whether expansion board installed in responding from I/O address. If data value returned by not equal undriven bus, then it known Otherwise, second performed, values certain control lines are latched driving those response read. so, again performs further special time. time faster than this way, map created for board. This used configuration comparing standard signatures boards. The passed software.
