Abstract

A technique is described whereby personal computers (PCs) are able to be "booted" from drive "B", as well as drive "A", which may contain various sizes of drives. The concept provides for logically remapping diskette drivers, at the basic input/output system (BIOS) level, to provide this function. (Image Omitted) Typically, PCs have the ability to function with various sizes of diskette drives, so as to accommodate diskettes with different diameters, such as 5.25" and 3.50" diameter diskettes. Since it is common to intermix the various sizes of drives in a system, it has been the practice to reserve only a specific diskette drive to provide the required "booting" capability. The concept described herein provides the ability to "boot" the system from either the "A" or "B" drive, and from the various sizes of diskette drives.
