MPBIOS(4) - Device Drivers Manual (amd64) # MPBIOS(4) - Device Drivers Manual (amd64) NAME # mpbios - MP BIOS SYNOPSIS # mpbios0 at bios0 DESCRIPTION # The mpbios 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. On modern systems this information is provided by ACPI through the acpimadt(4) device. ...
