No. These routines don't need to be on a ROM. The new routines can be written from scratch (yes, that's the hard thing), but once the routines are written they can be run from RAM. And forget about the BIOS completely (though most likely these routines should implement some kind of hardware detection, because disk controllers may be different on different MSX computers).
