Hi! I tested MenuetOS in Qemu and it works!
Suggestion: downloading 5 MB is heavy for people with dial-up(about 90%
of all internet visitors). So probably idea of bundling Qemu with
smaller OS then Linux one is more appreciated by those people. Zipped
MenuetOS is smaller then 1 MB, so developers can build package with size
about 1.8 MB or even smaller.
Question that I have is: I run my program CPUID in emulated MenuetOS and
got CPU signature (family, model, stepping) = 633.
So it is a Intel Pentium II codenamed Klamath with L2 cache = 128 KB.
But my program shows that is surprisely have SSE2 support (?), and some
problem with L1 data cache - unrecognized signature of its size, though
my program support all cache signatures from Intel docs.
Can you give me information about CPU which is emulated by Qemu? Maybe
piece of code which contain reaction to CPUID request?
Screenshot with running MenuetOS (and CPUID inside it) is here

Good luck!
