Some motherboards have a built-in display to diagnose hardware problems. Most also report POST errors with audible beeps, if a PC speaker is attached. Such motherboards make POST cards less necessary. When these diagnostic cards were first introduced motherboards were expensive and well worth troubleshooting and repairing.
Some motherboards that used Socket 370 support Intel processors in dual CPU configurations (e. g. ABIT BP6). Other motherboards allowed the use of a Socket 370 or a Slot 1 CPU, but not at the same time. A VIA C3 1.2 GHz Nehemiah C5XL CPGA socket-370 microprocessor. The VIA Cyrix III, later renamed the VIA C3, also used Socket 370.

Motherboard diagram, created in 2007, which supports many on-board peripheral functions as well as several expansion slots. The functionality found in a contemporary southbridge includes: [8] [2] PCI bus. A south bridge may also include support for PCI-X. Low speed PCI Express (PCIe) interfaces usually for Ethernet and NVMe. ISA bus or LPC ...
Also known as Full AT, it was popular during the era of the Intel 80386 microprocessor. Superseded by ATX. Baby-AT: IBM: 1985 216 × 254–330 mm (8.5 × 10–13 in) IBM's 1985 successor to the AT motherboard. Functionally equivalent to the AT, it became popular due to its significantly smaller size. ATX: Intel: 1995 305 × 244 mm (12 × 9.6 in)
As AM3 processors also support DDR2, they are backwards-compatible with Socket AM2/AM2+, contingent upon a BIOS update for the motherboard. Manufacturers including Asus , [ 7 ] Gigabyte , [ 8 ] and others have labeled existing AM2/AM2+ boards as being "AM3 Ready" or similar, indicating that BIOS support is provided for the specified boards.
In current practice, this has not been achieved; memory scrambling has only been designed to address DRAM-related electrical problems. The late 2010s memory scrambling standards do address security issues and are not cryptographically secure or open to public revision or analysis. [11] ASUS and Intel have their separate memory scrambling standards.
Prior to the development and ubiquitous adoption of the Plug and Play BIOS standard, an add-on device such as a hard disk controller or a network adapter card (NIC) was generally required to include an option ROM in order to be bootable, as the motherboard BIOS did not include any support for the device and so could not incorporate it into the BIOS's boot protocol.
