Since looking at this thread: Install 2000/XP/2003 from RAM loaded small ISO I started to wonder if it would be possible to combine the two projects (sort of). Would it be possible to boot a mini iso with the boot files (as flyakites guide - saves on boot time!) in RAM (0XFF) and direct boot the full iso (safes RAM) from the UFD (0XFE) then install from the full iso. Just a thought but I wondered if it would work. Edit: Nearly forgot... tested install on my desktop with and without card reader.
