|
|
.Nd "Vital Product Data kernel interface"
|
|
.Sh SYNOPSIS
|
|
.Cd "device vpd"
|
|
.Sh DESCRIPTION
|
|
.Tn IBM ThinkPad
|
|
notebooks (and most
|
|
.Tn 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
|
|
driver scans the BIOS area and claims the memory used by the VPD
|
|
structure.
|
|
It provides the
|
|
.Xr sysctl 3
|
|
branch
|
|
.Va 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):
|
|
.Pp
