RE: issue of booting USB w/o BIOS support, please see http://mirror.slitaz.org/floppies/ You'd need an HD floppy disk for this.
Floppy image set
This floppy set will boot a Slitaz stable version. You can write floppies with SliTaz bootfloppybox, Windows rawrite or simply dd:
- dd if=fd001.img of=/dev/fd0
If you have a CD-ROM, an USB port and an USB key or a network card, but you can't boot these devices directly, then try floppy-grub4dos  first. This 1.44Mb floppy provides tiny programs to boot these devices without BIOS support and some other tools.
