This is true - to the extent it _is_ true - only if you insist on video console. I find a break condition on serial console works well too. But I think that used to, and may still, depend on having a real serial port, which I gather recent machines may not, even if they have the connector for it. (I've heard it said they tend to have a USB-to-serial chip on an internal USB hub, though I have very limited experience with machines that recent.) As for USB keyboards, if you tell the BIOS to fake a real keyboard and then arrange for the OS to ignore the keyboard's USB existence, you may find yourself with a USB-hardware keyboard that looks like a PS/2 keyboard to the OS. But this may require disabling all OS knowledge of USB or something comparably drastic, which may or may not be an option for your use case. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
