+.Sh NAME
+.Nm stpcide
+.Nd STMicroelectronics STPC IDE disk controllers driver
+.Sh SYNOPSIS
+.Cd "stpcide* at pci? dev ? function ? flags 0x0000"
+.Sh DESCRIPTION
+The
+.Nm
+driver supports the STMicroelectronics STPC x86 SoC internal IDE controllers,
+and provides the interface with the hardware for the
+.Xr ata 4
+driver.
+The driver features DMA mode 2 and PIO mode 4 transfer speeds.
+.Pp
+The 0x0002 flag forces the
+.Nm
+driver to disable DMA on chipsets for which DMA would normally be
+enabled.
+This can be used as a debugging aid, or to work around
+problems where the IDE controller is wired up to the system incorrectly.
+.Sh SEE ALSO
+.Xr ata 4 ,
+.Xr atapi 4 ,
+.Xr intro 4 ,
+.Xr pci 4 ,
+.Xr pciide 4 ,
+.Xr wd 4 ,
+.Xr wdc 4
+.Sh 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.
