In one embodiment, a design is described for providing the BIOS instructions to a computer through the USB port. At boot-up, a USB controller checks the USB port for a bootable device containing BIOS instructions. If a bootable device is connected, the USB controller transfers the BIOS instructions through the USB port to the processor. The computer then boots-up using the USB boot instructions. If no bootable device is connected to the USB port, the computer looks to a standard BIOS EPROM for boot instructions.
