  • Emulating disk drives of a first system on a second system
    Patent number: 6006029
    Abstract: The emulation of a first system disk drive on a second processing system including a second system user level process including first system user and executive tasks issuing disk input/output requests. An emulator level is interposed between the second system user level process and a kernel level and includes a pseudo device driver corresponding to the first system disk drive and the kernel level includes a kernel process corresponding to the pseudo device driver and emulating the disk drive. The pseudo device driver and the kernel process execute in a second system process to emulate the operations of the disk drive and the kernel process emulating the disk drive is a file input/output process. The pseudo device driver includes a pseudo device queue, a return queue and a queue manager responsive to first system disk input/output instructions and to completed disk operations.
