Another thing, if you have a bootable USB/CF reader on your computer system, try to see if you can follow the CF drive as it boots up.

If not, get a dos 6.22 disk, and try putting the boot files onto the CF, and make sure you activate the boot partition on the CF too.

Another thing, make sure that you turn on the "make busy switch" after you have powered on the KSU. (Also remember to turn it - make busy switch - to "OFF" before you remove the drive).

Good luck.
