As discussed in Chapter 11, QEMU is an emulator that enables you to test (albeit verrrrrrrry slooooooowly) the Myppix ISO without having to burn it first.
To test Myppix with QEMU, run the following:
$ qemu -cdrom myppix.iso
Booting Myppix with qemu took more than 20 minutes from start to KDE. That's a long time to wait, but you'll be certain that myppix.iso is good and that your distro will boot.
