I am trying to install LCNC (debian12) onto a new second hand Dell desktop. I have copied configuration files across. but when I try to start the software I am getting this error:
iopl() failed: Operation not permitted

Note: Using POSIX realtime

Thanks for your reply. I will try it in the morning. Can you tell me what CMS is?

CSM, Compatibility Support Module, which helps newer bios's boot older styles of OSs.
