A computer system has a processing unit with suspend/resume capability, a memory, and a hard disk drive. In response to a first command from the processor, the hard disk drive sends its status to the processor and the processor stores it in the memory. In response to a second command from the processor, the hard disk accepts from the processor the status retrieved by the processor from the memory, and restores itself to this status. In an alternative embodiment, the hard disk drive response to the first command by storing its status on its own hard disk, and responds to the second command by restoring this status from the hard disk. In each case, an output line from the hard disk used to control a light emitting diode is also selectively used to create an interrupt to the processor which facilitates the systems entry into the suspend mode.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.] An apparatus comprising: a processor which executes an application program; storage means for storing data; a peripheral having a control circuit which has an operational status, said peripheral having means responsive to a request command from said processor for sending said processor a data block which includes the complete operational status of said peripheral; and interrupt means for interrupting said processor from execution of said application program in a manner invisible to said application program, for thereafter determining whether said peripheral has a busy status, for responding to a determination that said peripheral has a busy status by returning said processor to execution of said application program in a manner invisible to said application program and then invisibly interrupting execution of said application program again when said peripheral has a nonbusy status, for thereafter causing said processor to transmit to said peripheral said request command, and for thereafter accepting said data block from said peripheral and storing said data block from said peripheral in said storage means.
