Abstract
A BIOS may provide bad block and wear-leveling services to a flash memory during a boot cycle until a full-functioned memory controller, such as a software memory controller, is available. After the full-functioned memory controller is available, the controller may use data passed by the BIOS to determine what, if any, steps to take to account for write activity during the boot process. Alternatively, the BIOS may use a reserved portion of flash memory so that wear leveling for boot-related data, such as a shut-down flag, is not needed.
