Abstract
A computer system having two fixed disk drives and with a different operating system stored in each disk drive, in which selective booting and suspend/resume operation of the power management can be preformed through the two fixed disk drives. The computer system comprises a first hard disk drive storing a first operating system and a second hard disk drive storing a second operating system, each of the first and second hard disk drive has a reserved data storage area for the suspend operation. A port exchanger intervenes in the master and slave integrated drive electronics (IDE) interface signal lines leading from an integrated drive electronics (IDE) controller to the first and second hard disk drives, in response to a bus exchange control signal fed from a system controller to pass or cross switch the integrated drive electronics (IDE) interface signal paths directed to the first and second hard disk drives. The computer system further includes a controller for producing the bus exchange control signal, under control of the system management part by referring to the first and second hard disk drive status information during booting or resuming process.
