I have an intermittent problem with Super PC/Turbo XT BIOS version 3.1. About half the time my IBM 5150 PC will lock up when I try to reboot using Control-Alt-Delete. It remains locked up until the power is cycled off and then on. I'm using an extended 101 key keyboard, and when the PC locks up, all three LEDs on the keyboard flicker.
