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

              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>
                      </blockquote>
                      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>

                    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>

                  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>
