Uhr, but Or was talking about compiling and linking a ROM file as an
alternative to porting the OS to the Dreamcast platform. Of course if the

I did say 'without DOS' :) I know it's perfectly possible to run code from

controllers' low-level formatting routines to change drive interleaves, and
secondly my Psion palmtop runs all its apps and the OS from ROM.
