    BIOS POST card for ISA bus BIOS POST card for PCI bus Professional BIOS POST card for PCI bus Two POST seven-segment displays integrated on a computer motherboard. The original IBM BIOS made POST diagnostic information available by outputting a number to I/O port 0x80 (a screen display was not possible with some failure modes). Both progress ...

    en.wikipedia.org/wiki/POST_card

    POST cards for PCs, while originally high-priced, cost from just a few US dollars upwards in the 21st century. 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.

    DMI 1.0, introduced in 2004 with a data transfer rate of 1 GB/s with a ×4 link.. DMI 2.0, introduced in 2011, doubles the data transfer rate to 2 GB/s with a ×4 link.It is used to link an Intel CPU with the Intel Platform Controller Hub (PCH), which supersedes the historic implementation of a separate northbridge and southbridge.

    en.wikipedia.org/wiki/Serial_presence_detect

    In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module.Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.

    en.wikipedia.org/wiki/Platform_Controller_Hub

    Under the Hub Architecture, a motherboard would have a two piece chipset consisting of a northbridge chip and a southbridge chip. Over time, the speed of CPUs kept increasing but the bandwidth of the front-side bus (FSB) (connection between the CPU and the motherboard) did not, resulting in a performance bottleneck.

    There are a number of other companies (AMD, Microchip, Altera, etc.) making specialized chipsets as part of other ICs, and they are not often found in PC hardware (laptop, desktop or server). There are also a number of now defunct companies (like 3com, DEC, SGI) that produced network related chipsets for us in general computers.

    Intel i945GC northbridge with Pentium Dual-Core microprocessor. This article provides a list of motherboard chipsets made by Intel, divided into three main categories: those that use the PCI bus for interconnection (the 4xx series), those that connect using specialized "hub links" (the 8xx series), and those that connect using PCI Express (the 9xx series).
