stock ARAnyM might not emulate the timer C interrupt properly (simply
because host/libSDL does not offer fast enough timer) so you might want
to enable the RTC timer source in ARAnyM with
1) ./configure --enable-rtctimer --enable-fullmmu --enable-lilo && make
2) sudo sysctl -w dev.rtc.max-user-freq=1024
Without the RTC timer source ARAnyM sometimes has to double the timer C
interrupt - has to fire two subsequent irqs and perhaps linux 2.6.x does
not like that.
With the RTC timer running at 256 Hz it is able to emulate 100 Hz Timer
Wow... I just realized that kernel 2.6.x does no longer use 100 Hz
system timer. It uses either 1000 Hz or 250 Hz. Or is it ia32 only?
