When exactly do those 0x0s get sent? Before ram initialization starts? Before the initial banner is sent? Before the payload is executed? "before booting" can mean a lot of things ;)<br><br>-Corey<br><br><div class="gmail_quote">

<br>many thanks, now if we can figure out why it wont display upon bootup it will be great.<br><br>also, another thing which troubles me - BEFORE booting begins, there are 0x00 sent to the serial for about 2 minutes (i've counted about 80 o those 0x00 being sent) and only then the coreboot messages starts to appear and the boot continues. i would appreciate eliminating this 2 minutes delay... any relevant information would be appreciated.<br>

</div></div>coreboot uses a different pci.ids file than Linux. That's why Linux can<br>
find it but coreboot can't? Check and see if the coreboot pci.ids file<br>
includes 8086 / 7125. It may be missing and just needs to be added?<br>
