.Sh NAME
.Nm iteide
.Nd Integrated Technology Express IDE disk controllers driver
.Sh SYNOPSIS
.Cd "iteide* at pci? dev ? function ? flags 0x0000"
.Sh DESCRIPTION
The
.Nm
driver supports the IT8212 IDE controller which is found on some
Gigabyte motherboards (as
.Dq GigaRAID )
and some PCI cards.
This driver provides the interface with the hardware for the
.Xr ata 4
driver.
.Pp
The optional RAID functionality of the IT8212 is not supported and
is explicitly disabled by the
.Nm
driver.
The controller will act like a regular IDE controller with no RAID
functionality.
.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 AUTHORS
The
.Nm
driver was written by
.An Alexander Yurchenko Aq grange@openbsd.org
and ported to
.Ox
by
.An Grant Beattie Aq grant@NetBSD.org .
