Features a minimal boot prompt that starts the live OS in 8 seconds
The Live CD features a minimal boot prompt that has been designed from the ground up to automatically start the live operating system in eight seconds from the moment the user boots the ISO image from the BIOS of a computer, using either a CD disc or a USB flash drive of 512MB or higher capacity. A comprehensive list of boot options can be accessed by pressing the F2 key at the boot prompt. As always, press the Enter key if you’re in a hurry!
Minimal, old-school desktop environment for legacy computers
To access the graphical desktop environment, the user must first select a mouse device and a keyboard layout from a list, as well as the display server of choice. The graphical session features an old-school look, it is powered by IceWM and comprises of a single panel located on the bottom edge of the screen, from where users can launch applications and interact with running programs.
In conclusion, the Mini edition of Legacy OS is a great, super fast, lightweight and, of course, minimal operating system specifically designed for those of you are looking for a quick solution to turn an old PC into a reliable workstation.
