sorry, more details. Etherboot is loaded from FLASH and prints a prompt on the serial console. But if you send data to the serial port etherboot never sees it. It is as though the winbond com1 is not enabled for input (??) but output works fine.
This is all code that runs fine on the smartcore with its 37c672 superio. very odd, output but no input. Also, this serial console does work fine under the normal BIOS. ron
