No way. You will need to use serial port. Just plug the header to mainboard and
use some USB 2 serial from other computer (together with null
modem cable) if you need more info please let me know.
Do you have any links, diagram or picture for this method? Thanks
Yes sure. You will need at least those things:
1) serial header connector

You can take any from some old motherboard. Usually there where two variants of
pinout. The newer one fits the most mainboards. You need to plug it to a header
on the f2a85-m board. (pin1 to the color stripe on the cable) I think it is
called "COM header" in the manual.
2) null modem cross cable
The header from 1) needs to be plugged to 2)
This cable is very common. It is also called "crossed" cable with female/female
9 pin connector.

(female / female)
3) USB to serial cable
Either find some other computer which has a serial header (and you will need
second header from 1)) or buy this convertor. Most of them use pl2303 or ftdi
chip which is well supported under linux.

4) other computer (any laptop/desktop)
Plug in the USB serial with all cables plugged, and use /dev/ttyUSB0
use "minicom" or "hyperterminal" if you use windows. Set it 115200 8N1 (8 byte 1
stop bit no parity)
You should see some output of coreboot. Capture it via (ctrl a l shortcut in
minicom) to a file and send it back to list.
If is something unclear, please let us know. You need to make it up to next
Friday. I will be then long time AFK and I will back in March.
Thanks
