Hi Fabrice,

i see no speed increase with kqemu when i run my dos-based realtime
system. Most code is 16bit, does kqemu only work for 32-bit code segments ?

thx
kisda

kqemu works only on ring3 code ... iirc DOS spent most of its time in ring0
(this was not a problem for DOS since it was single user and uni-tasking),
which kqemu does not touch.
