Qemu does not do much in the BIOS (as a regular PC does while initializing various devices, reading boot records and so on), so there's nothing to hide here (except of problem reports in case of trouble - it's already waaay more than enough when people use -daemonize option which effectively turns off stderr). While booting the system it's possible to have its own splash screen if desirable. But the whole thing is somewhat moot for qemu anyway: just start whole thing in background. > Please don't accept these patches. *nod* /mjt
