Mandrake recently launched a package called "Globetrotter" that has Mandrakemove installed in an external USB drive and it includes a bootable cd (so they say) that can load a kernel and transfer to the HD if the BIOS can't boot directly from USB. However, they have not released any downloadable images that we can use. There is a knoppix cheat code that can do this for knoppix also, I believe. I've been trying to boot the decompressed cloop device in knoppix off of my external USB drive with no success either. I tried to use syslinux, but that worked only with my USB key. I've been tearing my hair out on this also.
