Hey there, I own a Dimension 4550 series dell with windows XP home SP2 dell dimension bios revision A08. I want to work with linux and boot it off of a USB drive. My problem is that my boot sequence says nothing about booting off of USB. It only has the usual Hard disk, CD or IDE device, floppy. On my friends new dell the boot sequence options include USB device. Is my problem the bios doesn't even support USB boot or am i missing some sort of drive. Thanks ahead of time Jamie
