1) do you port new motherboard ?I am.
Good. what superio is it? Some have a bit to trigger if clock source is 24MHz or 48MHz. Try to fidling with that.
We are on IRC irc.freenode.net #coreboot Rudolf
2) if you set speed to 115200 do you see something if you set on the other side 57600 or 28200 bauds? Both set to 115200, works fine with OEM BIOS to get linux console up. 3) if you set coreboot to 57600 and the other side to 115200 do you get something? Same 4) Sometimes when the clock is nearly 115200 but a bit off some USB serials cannot handle that. Maybe you can try to connect some other device, or try to test with some real serial line on some other PC. Works on another PC. If it is any help, minicom flicks between online and offline when doing it.

Rudolf David Houston napsal(a): Hi all, Would anyone have any suggestions why all I get out of my serial port when booting my coreboot build is ��FƢ���� =U$'E&&M#M y= �F ⌋!y= �F Ƌ!y=[$ M# MO"M y=+_Y�b��������������#⣉/y=+OIfyy=[$K KO K!K$L��� H#C1 �"b�㢢�VM K$LcDbD�b�#㢉 #㌢ #㢉 #㌢I know the usb converter is good as I have tested it on another machine. And I know the serial port is good as I have got a linux terminal up with the OEM Bios. I'm not sure what else to attach to help diagnose the issue. regards Dave ------------- r...@crankyadmin.net <mailto:r...@crankyadmin.net> <mailto:r...@crankyadmin.net <mailto:r...@crankyadmin.net>> cra...@archlinux.us <mailto:cra...@archlinux.us> <mailto:cra...@archlinux.us <mailto:cra...@archlinux.us>>
