Alan,
I have had one go at installing the Mepis Disk (thanks to Robert dropping it off this mng), I selected Normal Boot and it got as far as asking for a password but would not respond to any key on the keyboard, so not sure what I did wrong(probably something Simple or Stupid) so crashed out of it.
I've seen this when using a USB extension cord. If you have an extra USB cable plugged in to extend the cable, try removing it and plugging the keyboard directly in to the USB port on the computer. -- Later David Kirk
