  • Advanced firmware boot sequence x86 computer system that maintains legacy hardware and software compatibility
    Patent number: 6357003
    Abstract: An x86 based computer system that implements an advanced firmware based boot process without a conventional x86 BIOS. The computer system includes an x86 processor coupled to a volatile memory and a non-volatile memory via a bus, wherein the non-volatile memory includes an advanced firmware. The advanced firmware is executed by the processor to implement a boot sequence. During the boot sequence, the computer system initializes device drivers using the advanced firmware and interfaces with advanced firmware compliant program with the device drivers of the computer system. The computer system also initializes a virtual compatibility machine for supporting legacy software programs. The virtual compatibility machine includes a plurality of compatibility models.

  • Advanced boot sequence for an +86 computer system that maintains expansion card device compatibility
    Patent number: 6128731
    Abstract: An .times.86 based computer system that implements a firmware based boot process without an .times.86 BIOS that supports expansion devices coupled to the computer system, wherein the expansion devices include their own respective BIOS extensions. The computer system includes an .times.86 processor coupled to a volatile memory and a non-volatile memory via a bus. The non-volatile memory includes firmware which when executed by the processor cause the computer system to implement the boot process. The firmware initializes device drivers for the computer system and initializes an application programming interface for the device drivers. The firmware then initializes a compatibility component for interfacing with the device drivers, wherein the compatibility component is operable for translating accesses by a first software application to an .times.86 BIOS into corresponding accesses to the device drivers.

  • System for booting computer for operation in either one of two byte-order modes
    Patent number: 5524245
    Abstract: A system for abstracting the byte ordering of a computer firmware from the operating system by allowing a computer to automatically change endianness under full software control. The byte ordering can be switched completely transparent to the end user during system boot. The system is comprised of hardware and software to run either byte order stand alone software or operating systems on demand.
