"When you boot Finnix you will see a menu with several options.
Although Finnix is designed to automatically detect the type of
processor (either x86/AMD64 or PowerPC), you can still choose one
yourself. You can run other useful tools -- including Memtest86+, a
utility for memory hardware diagnostics -- from the boot menu. If
you want to boot multiple operating systems on the system disk, you
can use Smart Boot Manager, and for those who miss the DOS
command-line interface, you have FreeDOS."
