Abstract
A personal computer is BIOS configured to boot from an installed CD-ROM storing multiple operating systems in different partitions of the medium. The computer is initially booted from a user selected or default partition emulating a logical drive. With the original boot partition maintained active, emulation of additional partitions as other drives is performed when needed. This is accomplished in BIOS with multiple device tables, each dynamically associated with a logical drive letter. Hence, the system files found in only the original boot partition remain available to the system when other logical drives are called.
