NAME

     piixpcib -- Intel PIIX4 PCI-ISA bridge with SpeedStep

SYNOPSIS

     piixpcib* at pci? dev ? function ?
     isa* at piixpcib?

DESCRIPTION

     The piixpcib driver provides support for the Intel PIIX and compatible PCI-ISA Bridges with Intel's first generation SpeedStep.

     Frequency scaling is supported on Pentium III with two voltage modes, used by SpeedStep as power states low and high.  The driver will switch
     into low power state by reducing voltage and frequency of the CPU.  The factor depends on the processor itself, but will always reduce power
     consumption about 1/2.

     The user can manually control the CPU frequency with the sysctl(8) program using the following node:

	   machdep.speedstep_state = [0/1]

HISTORY

     The piixpcib driver first appeared in FreeBSD 5.5 and then in NetBSD 4.0.

AUTHORS

     The current piixpcib driver was written by Bruno Ducrot.  It was ported to NetBSD by Jared D. McNeill <jmcneill@NetBSD.org>.

PCIC(4) 						   BSD Kernel Interfaces Manual 						   PCIC(4)

NAME

     pcic -- Intel and Cirrus Logic PCMCIA controller driver

SYNOPSIS

     pcic0   at isa? port 0x3e0 iomem 0xd0000 iosiz 0x4000 flags N
     pcic1   at isa? port 0x3e2 iomem 0xd4000 iosiz 0x4000 flags N
     pcic*   at isapnp?
     pcic*   at pci? dev? function ?
     pcmcia* at pcic? controller ? socket ?

DESCRIPTION

     NetBSD provides support for the Intel 82365SL, Cirrus Logic PD6710 and PD672x PCMCIA controllers.

     For the isa(4) attachment a flags value of 1 can be used to force the use of polling instead of interrupts for card events.

     The default configuration of the pcic gives each controller 16 kilobytes of memory, to be shared between slots.  Some PC Card devices require
     somewhat more memory than this; it may therefore be necessary to adjust the iomem and iosiz parameters of the pcic devices in the kernel con-
     fig file to accommodate these cards.
