METHOD FOR USING FUNCTION INDICATORS TO DETERMINE COMPATIBILITY BETWEEN BIOS REVISIONS AND INSTALLED MATERIAL DURING FLASH MEMORY UPDATE

摘要

P The BIOS has two sets of flags: the first contains construction feature flags (202), the second contains primer functionality flags (204). The values that make up the build functionality indicators can be compared to the values that make up the boot functionality flags. The BIOS can be updated if the replacement build feature flags allow booting of an information system having a current build functionality. The comparison ensures that the functions necessary for a current operation of the information processing system (100) are present in the updated BIOS and that this does not prevent the operation of the information processing system such as currently configured. / P
