- All the 8000000x errors are CPU exceptions (privilege violation, illegal
- instruction, misaligned instruction, attempted line-A/line-F emulation on
- a CPU which doesn't support it, etc.). They are most commonly caused by
- a misbehaving (i.e. badly written or corrupted) program. So it's possible
- that you have one rogue program on your system that is corrupting the
- memory space of other programs and causing them to crash, _or_ that all
- the programs which crash are faulty themselves. The only way to isolate
- faults like these is to systematically remove non-standard programs (i.e.
- those not included with the OS itself) until you find the bad apples.
-
- Another possibility is that you have a dud memory chip somewhere, which
- is interfering with programs by corrupting their code. So the best thing
- to do is to find a memory testing program. There are a few of these on
- Aminet, for example:
-
- memtest.lha util/misc 12K 151+Memory Tester
-
- You should also try to find other hardware testing programs to ensure that
- none of your chips are obviously faulty. As I say, though, the most likely
- cause is a badly-written program somewhere.
