Hello Viktor,
I went thru your log file attached below, and I found a difference between our coreboot.rom which used the same Rangeley platform (Mohon Peak CRB).
would you please tell me how you generate this hightlighted mrc.cache file, I didn't find any configuration in 'menuconfig' or Kconfig files. My code base is 'RANGELEY_CB_POSTGOLD_001_20131218' which was downloaded from Intel website.
I've already googled 'mrc.cache' but hardly found much hits, what is this file for? could you please also give some hints :)
Thanks
May

From: Kuzmichev Viktor Date: 2014-12-25 16:45 To: coreboot Subject: [coreboot] SeaBIOS, serial output, grub, sgabios does not seem to load Hello,
I've been trying to boot grub installed on the hard drive using coreboot and SeaBIOS as a payload. The motherboard I'm using is Intel Mohon Peak. Also, I do not use VGA for output, only serial port. So, I included the sgabios into my rom file. Here is its layout:
$ ./build/cbfstool build/coreboot.rom print coreboot.rom: 8192 kB, bootblocksize 1024, romsize 8388608, offset 0x600000 alignment: 64 bytes, architecture: x86

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

The last five lines is clearly grub output, only after this goes nothing and it seems to me that sgabios does not forward VGA output to the serial port.
So, how do I fix that? Am I missing something?
