[coreboot] ASRock 939A785GMH/128M trouble

[Dmitry Samoyloff]

Hello!

I've tried to install Coreboot/SeaBIOS on my ASRock 939A785GMH/128M
motherboard [1], leaving it totally unbootable: no beeps, no VGA output :-(

I followed installation instructions from coreboot.org with SVN checkout,
"make menuconfig" and "make". The payload is SeaBIOS stable.

BTW, what makes me suspicious is a build process, the first "make" failed
with:

    <...>

However, the subsequent "make clean" and "make" ended up with success:

After that I copied build/coreboot.rom onto USB flash and installed it on
motherboard's flash successfully using "flashrom -w coreboot.rom". The
motherboard's chip is Winbond W25Q80, 1024 KB (this size is a default in
menuconfig, so I didn't changed it).

I will answer more questions if it's needed.

I'd also appreciate any help or hints on recovery, because now I can't even
boot. I tried that trick with AMIBOOT.ROM on USB flash and <Ctrl>+<Home>, but
it didn't worked for me.

Thanks in advance for your help!
