Abstract
Bootability of a computer system with multiple LUNs. A flash device powers-on into a default LUN, from which the system boots, maintaining any other LUNs unavailable. The first LUN reconfigures the system to remove itself as the available LUN, to load a second LUN as the only available LUN, and to reboot the computer system into the newly available second LUN. The second LUN reconfigures the system to load any additional LUNs, such as removable storage on the flash drive. Upon reconfiguration, the system includes multiple LUNs. The second LUN includes an interpolated LUN driver, which exposes additional LUNs before operation of other device drivers. The interpolated LUN driver takes control during boot-up, exposing any available LUNs before the regular environment's operating system.
