Line 12: == Well-known PICs == One of the best known PICs, the [[8259A]], was included in the [[x86]] PC. In modern times, this is not included as a separate chip in an x86 PC. Rather, its functionality is included as part of the motherboard's [[Southbridge (computing)\|southbridge]] chipset. In other cases, it has been completely replaced by the newer [[APIC\|Advanced Programmable Interrupt Controllers]] which support many more interrupt outputs and more flexible priority schemas. ==More Information== More information on the Intel 8259 PIC can be found in the ''IA-32 Intel® Architecture Software Developer’s Manual, Volume 3A: System Programming Guide, Part 1'', freely available on the [[Intel]] website. ==See also==
