Can you boot from these things? (Score 1)

I've got an older Dell 133mhz laptop with 1.6 gig harddrive that just isn't enough room for a dual boot system. I'd like to get one of these microdrives or one of the higher capacity flash memory cards and boot from it but I don't know how. I wonder if there's some tweaked version of my laptops bios out there or something.
