Jumper JP4: BIOS Flash Protect

The system BIOS and CMOS Setup Utility are stored in Flash memory on the motherboard, which provides permanent storage, but is rewritable, allowing for BIOS up- dates. Jumper JP4 controls the protection scheme that prevents accidental damage to or rewriting of the data stored in Flash memory.

JP4 has three setting options which allow the BIOS to be protected either by a firmware setting in the “IWILL Smart Setting” section of the CMOS Setup Utility or by the jumper’s hardware setting. The firmware setting option is more convenient, so it is the default setting for this jumper. The setting options are listed in the table below.
