ICHPCIB(4)                 BSD Programmer's Manual                  ICHPCIB(4)

NAME

     ichpcib - Intel ICHx/ICHx-M LPC bridges

SYNOPSIS

     ichpcib* at pci? dev ? function ?
     isa* at ichpcib?

DESCRIPTION

     The ichpcib driver supports Intel ICH, ICH0, ICH2, ICH2-M, ICH3-S, ICH3-
     M, ICH4, ICH4-M, and ICH-5 LPC bridges. These devices are mostly usual
     PCI-ISA bridges but with some additional power management and monitoring
     capabilities. Besides the core pcib(4) functionality, the ichpcib driver
     provides support for the Intel SpeedStep technology, available for the
     ICH2-M, ICH3-M, and ICH4-M chipsets. It allows the user to control CPU
     frequency with the sysctl(8) program.

SEE ALSO

     cpu(4), intro(4), isa(4), pci(4), pcib(4), sysctl(8)

HISTORY

     Intel SpeedStep support for the ICHx-M chipsets first appeared in
     OpenBSD 3.5 as part of the pcib(4) driver. The ichpcib driver first ap-
     peared in OpenBSD 3.6.

AUTHORS

     The ichpcib driver was written by Alexander Yurchenko
     <grange@openbsd.org>.

CAVEATS

     On some old machines with the ICH2-M chipset, Intel SpeedStep isn't
     available.
