[coreboot] coreboot Digest, Vol 113, Issue 17

Paul,

Attached please find the console log for coreboot and seabios (not really
anything).  

Since my board does not have a physical VGA adapter. I did not configure
anything for VGA in coreboot.  Do I need to configure anything to tell
coreboot to load the sgabios? As you can see in the log, there is nothing
indicating coreboot loading the sgabios.  

Thanks!

Wen

PS: I set my outlook to send plain text. Hope the setting works. :-)

welcome to coreboot! Please note that the official spelling of coreboot is
all lowercase. (Also SeaBIOS.)

I did not spot anything. Could you please attach/paste the whole coreboot
and SeaBIOS log?


Thanks,

Paul


PS: Could you please just send plain text messages, that means no HTML, to
the list? Big thanks in advance.
