NAME
     piixide -- Intel IDE/SATA disk controllers driver

SYNOPSIS
     piixide* at pci? dev ? function ? flags 0x0000

DESCRIPTION
     The piixide driver supports the Intel PIIX, PIIX3, PIIX4, and 82801 (ICH/ICH0/ICH2/ICH3/ICH4/ICH5/ICH6/ICH7/ICH8/ICH9/ICH10) IDE/SATA con-
     trollers and provides the interface with the hardware for the ata(4) driver.

     The 0x0002 flag forces the piixide driver to disable DMA on chipsets for which DMA would normally be enabled.  This can be used as a debug-
     ging aid, or to work around problems where the IDE controller is wired up to the system incorrectly.

SEE ALSO

BUGS
     The timings used for the PIO and DMA modes for controllers listed above are for a PCI bus running at 30 or 33 MHz.  This driver may not work
     properly on overclocked systems.
