 .Sh DESCRIPTION
 The
-.Nm
-driver provides support for PCI video capture on low cost, high performance
-boards.
-The driver is heavily based on the Matrox Meteor driver.
-The
-.Nm
-driver should support most video cards based on the
-.Em Brooktree Bt848 Video Capture Chip.
-.Pp
-Specifically, the following cards are known to work:

+high performance boards. This should support most video cards based on the
+Brooktree Bt848/849/878/879 Video Capture Chip.
+The driver also supports FM Radio if the Tuner supports it.

+On these cards, tuners and other components are interconnected with an I2C bus.
+The Brooktree848 chips act as a master device on the bus to control them.

-The following kernel parameters may be used to further configure the driver:
+The following kernel configuration options are available:

-.It Cd option "BROOKTREE_ALLOC_PAGES=xxx"
-Specifies the number of contiguous pages to allocate when successfully probed.
-The default number of pages allocated by the kernel is 216.
+.Bl -tag -width xxxxxxxx
+.It Cd option BROOKTREE_ALLOC_PAGES=nnn
+Specifies the number of contiguous pages to allocate when successfully
+probed.  The default number of pages allocated by the kernel is 216.
 This means that there are (216*4096) bytes available for use.
+.It Cd option BROOKTREE_SYSTEM_DEFAULT="(BROOKTREE_PAL | BROOKTREE_NTSC)"
+One of these options can be used to set the default video format for the driver.
+This fixed random hangs and lockups with the VideoLogic Captivator PCI card.
