==Dual BIOS==<br />
<br />
This board has a dual bios chip. Both chips are 8Mbit; the main bios is called M_BIOS, the backup bios B_BIOS. Gigabyte claims the backup bios can not be flashed by the user. It contains code that will overwrite M_BIOS if it determines that M_BIOS is corrupted.<br />
<br />
The M_BIOS chip is a [http://www.mct.net/download/macronix/mx25l8005.pdf Macronix MX25L8005].<br />
<br />
If you flash coreboot into M_BIOS and something goes wrong, you can force B_BIOS to boot and reflash M_BIOS by bridging pins 4 (GND) and 7 (#HOLD) on the M_BIOS chip, powering up the machine, and then releasing your bridge. The B_BIOS will take over at that point - you will hear a beep, and see the B_BIOS boot and forcibly re-flash M_BIOS.</div>
