Method and apparatus for booting from a selection of multiple boot images

摘要

A method and apparatus for booting from a selection of multiple boot images. Control logic is coupled with a plurality of memory devices containing a plurality of boot images. The control logic employs a device select value to map device requests to memory devices. An event agent monitors the apparatus for various events including a corrupted primary boot image. The event agent notifies the control logic when an event occurs and the control logic changes the device select value responsive to the event. The mapping from device requests to memory devices changes when the device select value changes.
