I use your cd from early in version 1 and I have always had a problem with entering the keyboard code. I must wait the twenty seconds to continue. Nothing on my Cherry Master Linux keyboard is picked up.
The only exception to this is when I boot your cd, wait the twenty seconds, do something wrong such as screwing up directory creation, then soft reboot the cd. When these steps occur, the keypresses are picked up. Don't know why.
I lived with this a long time. It is a minor inconvenience but the cd is worth it. I just read about other problems with the Cherry Master Linux keyboard and boot up so I thought I would pass this on.
The keyboard is not manufactured any more so you may or may not want to repair this defect.
