	I'd like to add rescue/ as really this should be the first bit of
code we do also with maybe a floopy utility disk to do the burn/recovery.
	Also as someone said we should first get the thing so it can boot
linux then work on the dos/win support. I imagine we need a very small
(code wise) consol interface that can be piped to teh vga card or the
serial port (for those who want serial config, one of the reasons this
project started i think) and to work in the mem/bus inits then move onto
the boot devices.
	Anyway enough speil from me.
	Cheers Adam
