Thanks for the reply, but unfortunately, as I wrote in my
original mail, I get nothing on the serial port.

When I boot the standard ASUS M2V BIOS, with a null-modem cable
plugged in, then exactly as I power on the M2V system, minicom on
the other end briefly (less than a second) switches from Offline
to Online, and then back to Offline, and then the system
continues to boot.

Booting coreboot, minicom switches from Offline to Online exactly
when I power on the M2V system, and then the minicom status on
the other machine remains Online, but nothing ever arrives in the
minicom terminal window, and nothing else happens (no beeps, not
LEDs, nothing on the screen, just plain nothing).

I have tested that the minicom connection over null-modem cable
between my M2V computer and the other machine works after booting
the standard ASUS M2V BIOS, although I then have HW flow control
enabled, which is then disabled before trying to boot the
coreboot BIOS. And yes, I have checked the serial port settings
in the coreboot config and they are set to the correct values.

So, anyone got a working .config and/or working coreboot.rom I
can try? A known working coreboot revision I should download and
compile? Or any other tips/pointers?
