I have a nice ASUS P5A-B that I am really happy with. One thing bothers me though, and it's probably just because of my lack of understanding. I am currently using it with a cheap PS/2 keyboard and an adapter to the 5 pin keyboard connector on the keyboard. But I would love to use it with my USB keyboard (a 60% mechanical keyboard). It seems that this keyboard doesn't support the PS/2 protocol. I tried using a passive USB -> PS/2 adapter but that doesn't work and gives me a keyboard error during post, as if no keyboard is connected.
However, the Asus board also has USB on a small extension board, which seems perfect for my use case. When I plug my keyboard directly into that, and boot the computer, I don't get a keyboard error, but the keyboard doesn't actually function. The lack of the keyboard error seems to indicate that the BIOS is satisfied when it comes to having a keyboard connected. But when I press ESC during the memory test in POST, it doesn't skip the test. Once in MS-DOS, the keyboard doesn't do anything. I can't go into the BIOS but that's because I don't have a physical DEL key. I have to check what key combination DEL is on my keyboard.
Does anyone know if this is even possible? Or is using an USB keyboard in MS DOS just not a thing?
