A free fully graphical desktop OS (no command prompt required, although it's available) for prehistorical machines like a Pentium II-450Mhz and 64 mb of RAM.

You will have software like VLC and a Be Media Player to play XVID/MPEG/MP3 files, Quake I-III, TONS of console/emulators, and so.

Fully graphical install with a bundled floppy image and a CD-ROM iso. Just write the floppy IMG with rawrite.exe for Windows, boot the computer from that disk and insert the CD. Next you will have a mouse based isntall.
