I am presently looking at trying to get Coreboot up and running on an ASUS F2A85-M system. I am however running into some issues.
Using a bus pirate and flashrom I first backed up the original bios, then erased the chip and restored the bios to ensure I had the basic read/write capability working and this all worked correctly.
Then I proceeded to build a standard coreboot image using seabios as a payload (using an external VGA card), leaving all the settings as default apart from selecting the motherboard, upon writing this to the flash and rebooting the machine I had no output from the VGA adapter and nothing from the serial port.
How did you burn the image? With the bus pirate, or from the board itself?
If the latter, that would explain your problem; I've seen flashrom seemingly do the right thing when reflashing coreboot over the proprietary bios, but the board not boot. I didn't have time to investigate that at the time, sadly.
Re-flashing with the bus pirate solved this for me. Note that you really still need to power off the board entirely (and let it sit a few seconds to allow the caps to drain) when switching between proprietary bios and coreboot.
For me this port works out of the box with the default settings. If you like I can send you a link to a known-good image that we use here, so that you can verify your hardware is ok.
