ProMEPIS Linux is a Linux OS based on Debian that can be run from your CD drive without installation. Where it shines is its easy, 100% "point and click" installation, and automatic detection of not only "normal" computer hardware but also popular webcams, the latest wireless network cards, "Winmodems" that usually work only with Windows, digital cameras, scanners, and other devices.

The difference between SimplyMEPIS and ProMEPIS is that SimplyMEPIS will continue to be a freely available desktop MEPIS bootable CD and ProMEPIS will designate an upcoming multi-CD packaged version of MEPIS.
