Hi all,
http://openbsd.org/42.html#new says
New piixpcib(4) driver for System Management Mode initiated
speedstep frequency scaling on certain pairings of the Intel
PIIX4 ISA bridges and Intel Pentium 3 processors.
Now I wonder which certain pairings are supported. My HW is
cpu0: Intel Pentium III ("GenuineIntel" 686-class) 399 MHz
piixpcib0 at pci0 dev 7 function 0 "Intel 82371AB PIIX4 ISA" rev 0x02
piixpm0 at pci0 dev 7 function 3 "Intel 82371AB Power" rev 0x03: SMI
iic0 at piixpm0
isa0 at piixpcib0
How do I find out whether there is hope for me to get
speedstep frequency scaling?
Thanks
Jan
