Re: Reg: Intel Rangley Support in EDK

["You, Benjamin" <benjamin.you@intel.com>]

Hi Dhanasekar,

The Coreboot UEFI Payload does support serial and terminal. As Nate said 
below, there may be some configuration issue causing the display not correctly
formatted through serial terminal.

I also agree with Nate that since your board does not have a VGA connection, 
you might have to configure Ubuntu to use serial console to monitor the boot 
process.

Thanks,

- ben
