Well, unfortunately I wasn't able to figure out how to boot from USB on my other machine either, I tried various settings in the BIOS for using my SD card, but I never did get a boot from it. So either it isn't working correctly (can one use an SD card and reader as opposed to a USB stick?) or I just don't know what I'm doing. And yes, I used the script to format the SD card and make it the puredyne live system.
Anyways... since none of that seemed to work, I decided to go ahead and try the liveHD, which aside from a few minor snags went fine. Just to point out, the menu.lst file in the /extra/grub directory has the kernel pointing to /live/vmlinuz1 and also /live/initrd1.img when the files in the /live directory are named simply vmlinuz and initrd.img. After changing that the system booted just fine. I am a bit confused as to how to define the persistent medium (i have a logical ext2 partition named live-rw i want to use) but I also haven't really done much digging yet either. A few questions: What is the grub.cfg file in the extra folder and should I do something with it for my liveHD install? Is there anything to be aware of when installing packages to a liveHD system? or does that even work? Could I simply use the liveHD to do a full installation? It seems kind of silly and I don't really know what the differences are between the two exactly.
