+.Os
+.Sh NAME
+.Nm mpbios
+.Nd MP BIOS
+.Sh SYNOPSIS
+.Cd "mpbios0 at bios0"
+.Sh DESCRIPTION
+The
+.Nm
+driver extracts configuration information from the BIOS on
+multiprocessor systems that conform to the Intel MultiProcessor
+Specification.
+This information is used to attach application processors and APICs,
+and to assign interrupts to ISA, EISA and PCI devices.
+.Pp
+On modern systems this information is provided by ACPI through the
+.Xr acpimadt 4
+device.
+On such a system
+.Nm
+will not attach, even if the BIOS also contains the data structures
+specified by the Intel MP Specification.
+.Pp
+The
+.Nm
+driver supports version 1.1 and 1.4 of the Intel MP Specification.

+.Xr intro 4 ,
+.Xr ioapic 4 ,
+.Xr pcibios 4
+.Sh HISTORY
+The
+.Nm
+driver first appeared in
+.Ox 4.5 ,
+based on code present since
+.Ox 3.6 .
