NAME
     aceride -- PCI IDE disk controllers driver

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

DESCRIPTION
     The aceride driver supports the Acer Labs M5229 IDE controllers, and provides the interface with the hardware for the ata(4) driver.

     The 0x0002 flag forces the aceride 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
     ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4)

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.
