Method of efficiently detecting whether a device is connected to an information processing system by detecting short circuits to predetermined signal lines of an IDE interface
摘要:
A strap pin short-circuits specific signal lines on an unused interface an IDE interface with which a hard disk is connected. When the server device starts, a BIOS skips the process for recognizing the IDE interface when specific lines of an IDE interface are short-circuited.
