No - not poking fun and I don't believe that any user should have access to interrupts. This programme is compiled/run as root. > >The whole purpose of the Linux kernel is to protect the hardware from the >user processes.

Please check the source code of svgatextmode and svgalib. I tried checking the source code of svgalib - if it's going to remain as difficult as it seems I may find a simpler project. I was hoping that there would be a simple method of getting permission from the kernel for this operation and for direct access to video memory/registers. Thanks for the reply Marcus. Ivan.
