<div> </div>
<div>I've been trying to boot grub installed on the hard drive using coreboot </div>
<div>and SeaBIOS as a payload. The motherboard I'm using is Intel Mohon Peak. </div>
<div>Also, I do not use VGA for output, only serial port. So, I included the </div>
<div>sgabios into my rom file. Here is its layout:</div>
<div> </div>
<div>$ ./build/cbfstool build/coreboot.rom print</div>
<div>coreboot.rom: 8192 kB, bootblocksize 1024, romsize 8388608, offset 0x600000</div>

<div> </div>
<div>The issue is, it looks like SeaBIOS does not load sgabios at all.</div>
<div>Here is the SeaBIOS output, debug level 7 (I also put it in the attachment):</div>

<div>The last five lines is clearly grub output, only after this goes nothing </div>
<div>and it seems to me that sgabios does not forward VGA output to the </div>
<div>serial port.</div>
