- This item has been discussed quite some time last year.
- I.) It is impossible to run a complete AmigaOS emulation on a Unix box,
- since the emulation of the hardware is too complex.
- II.) Unix and AmigaOS can not be run concurrently, since AmigaOS accesses the
- hardware directly and this is not allowed on a Unix environment, since
- e.g. the usage of the system timers, interrupts, display hw can not be
- seperated, without big, big changes in AmigaOS. Anyhow, AmigaOS is not
- multi user clean: One process may crash others without no effort, so
- it is not wise to have this OS share the critical parts of the machine, like
- interrupts, etc.
-
- There is IMHO no way of coexistance of AmigaOS and Unix since there concepts
- are to different. AmigaOS is the faster OS, but Unix is safer. So live with it.
