Phani,
The DB800 coreboot configures the Winbond SIO. There have been some reported problems with the SIO buffers getting messed up. I don't recall the exact symptom but try completely powering off the system by unplugging or power off the ATX power supply and press the power button to get rid of any on-board capacitance. If this is your problem there should be reword instructions from Logic or on the AMD embedded developer site.
The video ROM would need to go before the VSA in the ROM image. VSA is expected to be on the end. See do_vsmbios().

Marc,
Yes I have tested and I can see the messages. Do I need to check how the serial port on DB800 board has been routed. Looks like the Config ROM expects it to be on 3f8 and take out from the Winbond Super IO. If the board has picked up the serial port either from the sourth bridge of else if its using some other port then that could be the reason for this.
How about the Video ROM image does it go after VSA or before that ?
Regards, Phani

Phani, It should just work. Have you tested a serial console with the normal BIOS in Linux? Marc -- Marc Jones Senior Firmware Engineer (970) 226-9684 Office mailto:Marc.Jones@amd.com <mailto:Marc.Jones@amd.com> http://www.amd.com/embeddedprocessors
