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.

Uncompress the 7Z archive with 7-Zip an burn the folder to a CD-ROM. To install a program in BeOS, just either uncompress it in a folder and run it, or install it with an assistant. Easier than Windows.
