the problem is not the usb stick, but the fact that plan 9 does not recognize the usb stick as a floppy disk as it is not using the bios calls. it is the bios calls that map requests to the floppy disk and map them to the usb.
thus 9load cannot find plan9.ini. the easy (but oh-so-wrong) might be to have 9load stay in 16bit mode long enough to probe the "floppy" for plan9.ini. and stick it someplace useful before branching running 9load proper. a better but more involved fix might be to switch to 16bit mode and call bios for floppy access. this is more complicated but could pave the way for 9load using universal drivers (part of the pxe standard) to load the kernel proper instead of modified versions of the cpu kernel drivers. - erik
