Hello, Thanks for your reply. Currently I use sgabios as advised by Kevin O'Connor but it would be great if SeaBIOS could deal with keyboard over serial as a builtin feature. MAYBE I will try to include the uart_check_keystrockes myself in the seabios code as you said it's the main fonction for that feature. But I don't know anything about that kind of environment (serial, very low level programming…). But I just brick my apu1d4 trying to understand why I can't see anything on the console when I run my memtest86+ build. So I will not be able to test anything before I received the lpc1aapu I just order to unbrick the board. By the way if you want to test some coreboot/seabios build/feature on my apu1d4 it will be with pleasure. As I will soon have a way to unbrick it if things goes wrong. > SageBIOS payload extracted from original apu1 firmware might work > with keyboard interaction on serial, I don't remember if I ever tried > it. Do it this way, and you lack any SeaBIOS updates from last 18 or > so months. It's not very clear for me… Do you mean Seabios have to be able to handle serial "keyboard input" for the payload it run to be able to handle it itself ? (I really doubt about the english rightness of this sentence) What I mean is : In order for memtest86+ to be able to handle serial input/output does Seabios have to be able to handle it too ? If that's the case, does sgabios is a sufficient/working workaround ? That leads me to another question : If I disable serial debug output in Seabios and add sgabios to deal with the serial input/output. Does sgabios will also handle serial input/output for all the payload Seabios will launch ? So, should I enable or disable the serial support on memtest86+, coreinfo, nvramcui and all the other payload I want to add in the rom ? -- Again, thank you for your answer… and in advance thanks for the others to come :) Regards Maxime de Roucy
