Mac Pro 2008 no bootable media. No keyboard.
No matter if drives are installed or not the same message keeps popping up. Mouse gets power so I know USB ports are working but it doesn't recognise the keyboard. I've even tried pc keyboards and nothing. No boot camp is installed either. These are straight 10.7 and 10.11. OS X disks. each os is on its own drive. No multiple partitions. Any help would be greatly appreciated.
Mac Pro, Mac OS X (10.7.5)
