A computer system is disclosed that includes: a communications bus implemented in accordance with an Inter-IC bus specification; a bus controller coupled to the communications bus; a send machine coupled between a host processor and the bus controller; and a first-in first-out (FIFO) buffer coupled to the send machine and coupled between the host processor and the bus controller.

Communications bus transceiver

A machine-readable identification register is provided on each cell of a cellular computer system. The identification register is read during system startup to identify a processor type, which may include an instruction set architecture (ISA), associated with the cell. The processor type information is used to ensure that a compatible boot image is provided to processors of the cell. In another embodiment, the system management subsystem has a version selection flag. When the version selection flag is in a first state, the compatible boot image provided to processors of the cell is a current boot image; with the selection flag in a second state the compatible boot image provided to processors of the cell is an older edition of the boot image.

Apparatus and method for selectively mapping proper boot image to processors of heterogeneous computer systems

Techniques and apparatus are disclosed for detecting and responding to the malfunction of a host coupled to a communications bus through a bus transceiver.
