NAME
     acardide -- acard IDE disk controllers driver

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

DESCRIPTION
     The acardide driver supports the following IDE controllers:

	   Acard ATP850U Ultra33

	   Acard ATP860 Ultra66

	   Acard ATP860-A Ultra66

	   Acard ATP865-A Ultra100

     It provides the interface with the hardware for the ata(4) driver.

     The 0x0002 flag forces the acardide 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.
