This guide is for those who want libreboot on their Intel GA-G41M-ES2L
motherboard while they still have the original BIOS present.

<p>
Refer to <a href="bbb_setup.html">bbb_setup.html</a> for how to
set up the BBB for external flashing.
</p>
<p>
Here is an image of the flash chip:<br/>

</p>
<p>
Internal flashing is possible. Boot with the proprietary BIOS
and GNU/Linux. There are 2 flash chips (one is backup).
</p>
<p>
Flash the first chip:
<br/>
<strong>./flashrom -p internal:dualbiosindex=0 -w libreboot.rom</strong>
</p>
<p>
Flash the second chip:
<br/>
<strong>./flashrom -p internal:dualbiosindex=1 -w libreboot.rom</strong>
</p>
<p>
NOTE: You need the latest flashrom. Just get it on flashrom.org from
their SVN or Git repos.
</p>
<p>
NOTE: due to a bug in the hardware, the MAC address is hardcoded in coreboot-libre.
Therefore, you must set your own MAC address in your operating system.
