When the “CMOS checksum error - Defaults Loaded” message is displayed,execute the “Load Optimized Defaults” and at least confirm or change the dateand time.Advanced BIOS Features These features set fundamental BIOS items, such as the cache, POST conditions,bootup sequence and memory shadowing.Advanced Chipset Features These features set items related to memory timing, BIOS code cashing, videomemory timing and the chipset control timing. Since these settings are executedvia the Load Optimized Defaults, they are the optimum settings for the system andgenerally do not need to be changed.
