BIOS Switch and BIOS LED Indicators
The BIOS switch (BIOS_SW) allows users to easily select a different BIOS for boot up or overclocking,
helping to reduce BIOS failure during overclocking. The SB switch allows enabling or disabling of the Dual
BIOS function. The LED indicator (MBIOS_LED/BBIOS_LED) shows which BIOS is active.
