+.Sh DESCRIPTION
+The
+.Nm
+driver is a generic video card driver which provides access to
+video cards.  This driver is required for the console driver
+.Xr syscons 4 .
+The console driver will call the
+.Nm
+driver to manipulate video hardware (changing video modes, loading font, etc).
+.Pp
+The
+.Nm
+driver supports the standard video cards: MDA, CGA, EGA and VGA.
+In addition, the driver can utilize the VESA BIOS extension,
+if the video card has one.
+VESA support can either be statically included in the kernel or
+available as a separate module.
+.Pp
+In order to statically link the support to the kernel, define the
+.Em VESA
+option (see below) and the
+.Em VM86
+option in the kernel configuration file.
+.Pp
+The
+.Nm vesa
+module can be loaded to the kernel, without static VESA support, by
+.Xr kldload 8 .
+The
+.Em VM86
+option is required in the kernel configuration file in this case too.
+.Sh DRIVER CONFIGURATION
+.Ss Kernel Configuration Options
+The following kernel configuration options control the
+.Nm
+driver.
+They may be set in the kernel configuration file 
+.Pq see Xr config 8 .
+.Pp
+The following options are to provide compatibility with certain VGA
+cards.
+.Bl -tag -width MOUSE
+.It Em VGA_ALT_SEQACCESS
+You may want to try this option if the mouse pointer is not drawn correctly 
+or font does not seem to be loaded properly on the VGA card. 
+However, it may cause flicker on some systems.
+.It Em VGA_SLOW_IOACCESS
+Older VGA cards may require this option for proper operation.
+It makes the driver perform byte-wide I/O to VGA registers and
+slow down a little.
+.El
+.Pp
+The following options add optional features to the driver.
+.Bl -tag -width MOUSE
+.It Em VESA
+Add VESA BIOS support to the driver.
+If the VGA card has the VESA BIOS extension 1.2 or later, 
+this option will utilize the VESA BIOS service to switch to high
+resolution modes.
+This option requires the 
+.Em VM86
+option.
+.It Em VESA_DEBUG=N
+Set the VESA support debug level to N.
+The default value is zero (all debugging output is suppressed).
+.El
+.Pp
+The following options will remove some features from the
+.Nm
+driver and save kernel memory.
+.Bl -tag -width MOUSE
+.It Em VGA_NO_FONT_LOADING
+The
+.Nm
+driver can load software font to EGA and VGA cards.
+This option removes this feature.
+.It Em VGA_NO_MODE_CHANGE
+This option disallows the driver to change video modes.
+.El
+.\".Sh FILES
+.Sh EXAMPLE
+Your kernel configuration should normally have:
+.Pp
+.Dl "device vga0 at isa? port ? conflicts"
+.Pp
+The following lines should be included in the kernel configuration file
+in order to enable the VESA BIOS Extension support.
+.Pp
+.Dl "options" \&"VM86\&"
+.Dl "options" \&"VESA\&"
+.Dl "device vga0 at isa? port ? conflicts"
+.Pp
+If you do not want the VESA support always included in the kernel, but
+want to use occasionally, add the following lines to the kernel configuration
+file.
+.Pp
+.Dl "options" \&"VM86\&"
+.Dl "device vga0 at isa? port ? conflicts"
+.Pp
+And load the
+.Nm vesa
+module, when desired, as follows.
