Abstract
An apparatus and method for loading BIOS stored on a direct access storage device into a personal computer system. The personal computer system comprises a system processor, a system planar, a random access main memory, a read only memory, and at least one direct access storage device. The first portion of BIOS initializes the system and the direct access storage device to read in a master boot record into the system from the direct access storage device. The master boot record includes a data segment and an executable code segment. The first BIOS portion vectors the system processor to execute the executable code segment of the master boot record. The executable code segment loads in the remaining BIOS portion from the direct access storage device into random access memory.
