Yes, for SeaBIOS I did just like you wrote. However, sgabios may
only be configured by modifying the source files.<br>

<div>Changing the seabios serial port base address, you should
modify it via "make menuconfig" command, it's much easy and

Yes, I think having option roms checked is probably
required. The only other thing I'd recommend is to build
SeaBIOS outside of the coreboot structure and pull it in as
an elf payload. Building within coreboot is handy, but it
doesn't offer the flexibility or control that you get
building it yourself.<span class="HOEnZb"><font

Hello,<br>
<br>
I've been trying to boot grub installed on the
hard drive using coreboot and<br>
SeaBIOS as a payload. The motherboard I'm using
is Intel Mohon Peak. Also, I<br>
do not use VGA for output, only serial port. So,
I included the sgabios into<br>
my rom file. Here is its layout:<br>

It should have worked. How did you build SeaBIOS,
what SeaBIOS config<br>
did you use, and what changes have you made to
SeaBIOS?<br>
<br>

As I recall, Mohon Peak uses 0x2f8 for the console
serial port. Did you set sgabios to output to 2f8
instead of 3f8 in sgabios.h?<br>
<br>
sgabios.h:#define COM_BASE_ADDR 0x3f8<br>
<br>
Martin<br>

Thank you for your replies!<br>
<br>
Just checked sgabios.h and changed serial port base
address to 2f8. Somehow I missed it earlier, although
I did set this parameter in both coreboot and SeaBIOS
before. Sadly, I do not currently have access to Mohon
Peak, so I can't really test this right now but,
hopefully, I would be able to test this in a few days.<br>
Also, I'd like to clarify one more thing. Should
Option ROMS parameter in SeaBIOS menuconfig be checked
for sgabios to work? Are there any other nuances I
should keep in mind?<br>
