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

     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.

NAME

     stpcide -- STMicroelectronics STPC IDE disk controllers driver

SYNOPSIS

     stpcide* at pci? dev ? function ? flags 0x0000

DESCRIPTION

     The stpcide driver supports the STMicroelectronics STPC x86 SoC internal IDE controllers, and provides the interface with the hardware for
     the ata(4) driver.  The driver features DMA mode 2 and PIO mode 4 transfer speeds.

     The 0x0002 flag forces the stpcide 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 DMA and PIO modes are for STPC Atlas and its siblings with their PCI clock configured at 33 MHz.	Other speeds
     including the STPC Vega Ultra-IDE controller will need adjustments.
