Abstract
In a computer operating a bootable CD-ROM or other bootable media having the capability of emulating one or more real drives, BIOS emulation parameters, such as drive number, memory partitioning and mapping are moved from BIOS and stored in a protected region of main memory. Upon a change of media, e.g., hard file, diskette, etc., as the computer undergoes a warm boot with new BIOS emulation parameters to enable DOS to process the change, the protected region of memory is not cleared. This preserves the BIOS emulation parameters which are restored to BIOS for the remainder of the boot sequence.
