The ABIT BP6 is an ATX motherboard released by ABIT in 1999. It was the first motherboard to allow the use of two unmodified Intel Celeron processors in dual symmetric multiprocessing (SMP) configuration. This combined with its overclocking capabilities made it a popular option among computer enthusiasts.{{cite web |url=http://archive.arstechnica.com/reviews/3q99/bp6/bp6-1.html|title=Abit BP6 Dual Socket-370 Motherboard |website=Ars Technica |author1=Gonzo |last2=Fisher |first2=Ken "Cæsar" |access-date=2017-07-19 |archive-url=https://web.archive.org/web/20160213185344/http://archive.arstechnica.com/reviews/3q99/bp6/bp6-1.html|archive-date=2016-02-13|url-status=dead}} The BP6 has been credited as the product that made multi-processor systems affordable for mainstream users,{{cite web|url=http://www.maximumpc.com/article/features/mobos_mattered_most|title=Mobos that Mattered the Most |date=2010-10-14 |last=Ung|first=Gordon Mah |website=Maximum PC| publisher=Future US, Inc.| archive-url=https://web.archive.org/web/20150319073821/http://www.maximumpc.com/article/features/mobos_mattered_most |archive-date=2015-03-19 |access-date=2017-07-19}} because prior to its release the expense of any multi-processor configuration made it a feature only to be considered for workstation-class systems.

The BP6 was based on the Intel Seattle 440BX chipset, consisting of the 82443BX Northbridge and the 82371AB Southbridge.

Processors that are supported by the BP6 in SMP configuration are the PPGA Socket 370 Celeron processors (300–533 MHz). Later Pentium III and Celeron Coppermine models can also operate on the BP6, albeit only in single processor configuration with the use of aftermarket socket adaptors. Intel never intended the Celeron to be able to operate in SMP, and later-generation Celeron processors had their SMP interface disabled, restricting the feature to the higher-end Pentium III and Xeon product lines.

The motherboard also features two extra HDD ports, one with the HPT366 Ultra DMA/66 adapter fitted on the mainboard itself. This allows up to eight IDE compatible drives to operate at the interface's maximum speed.

The BP6, and many other of ABIT's motherboards produced between 1999 and 2005, were victims of the capacitor plague.{{cite journal |author= |date=February 2005 |url=https://books.google.com/books?id=rwIAAAAAMBAJ&pg=PA24 |title=Busting Caps |work=Maximum PC |publisher=Future Publishing |page=24 |via=Google Books}}
