Hi,
I am working to make a minimal linuxbios without any payload or linux
kernel, I just want to see a nice hello word string on the serial port
and nothing else. is it possible to make such a bios? also to setup only
the necessary HW registers and memory to see the printout message.
how should i do this?
Look at SerialICE:
http://www.serialice.com/News/News.html
This is a mini monitor that runs over the serial port. The coreboot
developers use it to step through a BIOS image, but it contains
just enough to get the serial port working. Memory is not
initialized, so everything is done with registers.
