When I switch on my computer, on the POST screen I get a "Keyboard Not Detected" error (mobo - Asus M4N78 Pro). This is using a serial keyboard.
After it posts and the OS starts up; I am then able to use the keyboard. If I connect the keyboard to a serial to USB converter; I am able to get it working and can enter the BIOS. Is the a setting in the BIOS that can be causing the keyboard not to be flagged as being attached at POST.
