Defective BIOSes may not set up interrupt routing properly, or provide incorrect ACPI tables and Intel MultiProcessor Specification (MPS) tables.

Version 1.1 of the specification was released on April 11, 1994. Version 1.4 of the specification was released on July 1, 1995, which added extended configuration tables to improve support for multiple PCI bus configurations and improve expandability. The Linux kernel and FreeBSD are known to support the Intel MPS.
