OK.

With the 845 comes an ACPI timer whose frequency is 3 times the
frequency of timer0.
Actually, both timer0 1,193,182 Hz and APIC timer 3,579,545 Hz are
derivated from standard PC basic frequency of 14,318,180 Hz (1193182 =
14318180 / 12, 3579545 = 14318180 / 4).
XP very probably implements the 'Performance' functions with the ACPI
timer, which is ignored by CEPC standard implementation.

hi Gravelaine

now i know that standard CEPC implementation work with timer0 1,193,182 Hz
and xp work with APIC timer 3,579,545 Hz.

can this frequency different effect on speed run of application?

In other words the application that run in xp is 3 times faster than Ce ?

thanks for replay
