Abstract
A system for causing a computer solid state memory to emulate a magnetic disk mounted in a disk drive. In the preferred embodiment, the system includes two removable RAM cards and two ROM's. Program instructions encoded in firmware in the system BIOS translate disk service requests from software running on the computer into appropriate commands and addresses on the RAM cards or on the ROM. The system permits software written for use with floppy disks to be used with solid state memory devices such as RAM cards or ROM without modification of the software.
