</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.
