It is actually the sixth version of the demo made available for public, and this time the focus is on UEFI boot. As demo, the software is not intended to be installed, even if with little effort this can be done. We are providing text mode cd iso and usb image, the usb image is self contained and can be written directly to the stick. Both images are built universal, to boot from BIOS and UEFI systems.
