+.Sh NAME
+.Nm vpd
+.Nd "Vital Product Data kernel interface"
+.Sh SYNOPSIS
+.Cd "device vpd"
+.Sh DESCRIPTION
+IBM ThinkPad notebooks (and most IBM desktop PCs) have a 48-byte
+Vital Product Data (VPD) structure located in the BIOS Shadow RAM.
+.Pp
+The VPD provides machine type and model information, the build ID
+(this is roughly the BIOS version) and serial number information.
+.Pp
+The
+.Nm vpd
+driver scans the BIOS area and claims the memory used by the VPD
+structure.  It provides the
+.Xr sysctl 3
+branch  hw.vpd to allow this information
+to be accessed by the userland.
+The following variables are provided, one per VPD attachment (there should
+only be one):
+.Bl -tag -width -indent
+.It Dv MACHINE_TYPE
+.Pq machine.type
+Machine type.
+.It Dv MACHINE_MODEL
+.Pq machine.model
+Machine model.
+.It Dv BUILD_ID
+.Pq build.id
+BIOS Build ID.
+.It Dv SERIAL_BOX
+.Pq serial.box
+Box Serial Number.
+.It Dv SERIAL_PLANAR
+.Pq serial.planar
+Motherboard Serial Number.

+.Sh HISTORY
+The
+.Nm
+driver and manual page example first appeared in
+.Fx 5.1 .
+.Pp
+.Sh AUTHORS
+This
+manual page was written by
+.An Matthew N. Dodd Aq mdodd@FreeBSD.org .
+.Sh BUGS
+The checksum code isn't quite correct so we're not able to detect
+a corrupt VPD structure.
