Abstract:
1. A method of recovering from basic input/output system (BIOS) corruption in a multi-node computer with a first node including a first central processing unit (CPU) hub and a second node including a second central processing unit (CPU) hub, a first firmware unit in the first node, a second firmware unit in the second node, and a multi-port switch for internodal communications the method comprising: configuring the multi-port switch to provide a communication path between the first CPU hub and the second CPU hub with an error recovery code; in response to initiation of a boot sequence for the multi-node computer, automatically checking a BIOS image in the first firmware unit in the first node of the multi-node computer for corruption; determining if the second firmware unit contains a good copy of the BIOS image; and in response to detecting corruption of the BIOS image in the first firmware unit, and in response to determining that the second firmware unit contains a good copy of the BIOS image, automatically recovering from the corruption of the BIOS image by copying a good BIOS image from the second firmware unit in the second node to the first firmware unit in the first node.
