ABSTRACT:
A system for enabling booting to a desired drive of a computer system having a floppy drive, an IDE/EIDE storage drive, and a SCSI storage drive. The system includes a floppy disk that is configured to be inserted into the floppy drive. The floppy disk contains a media containing program instructions that are configured to be executed upon initiating a system BIOS of the computer system. The execution of the program instructions includes executing a boot code stored on the media of the floppy disk. The boot code is configured to scan a number of PCI buses of the computer system to identify host adapters that are connected to respective ones of the number of PCI buses. Further, the system includes executing a BIOS code for each of the host adapters which causes an assignment of drive numbers to devices connected to the host adapters and the computer system. Then, swapping the assignment of drive numbers such that the desired drive is assigned a drive number 80h. The master boot record (MBR) of the desired drive will then be accessed upon an INT 13 call, which causes the completion of the boot process that enables an operating system (OS) stored in the desired drive.
