Are you wondering why your getting the errors or is it you can't select either option? The error message may be caused by a failing battery on the motherboard. Once powered down it loses some or all of the settings in bios. F1 opens the bios and lets you change settings one by one. F9 sets it at the factory default (recommended). I've worked on a couple of these and they were meant for usb everything. If the keyboard won't respond to pressing F anything, try plugging the keyboard into a different port. I found this always gets the keyboard back to working. When you press F9 and it reboots and all seems well, and then if you get the same error after a complete power down, the battery is probably shot.
