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 ...
Two POST seven-segment displays ("Q_CODE1" and "Q_CODE2", lower-left), integrated on a computer motherboard. Diagnostic cards are today mainly used by designers of motherboards and extension cards, along with logic analyzers and other debug tools and interfaces. They are less commonly used in the 21st century for computer repair and by system ...

On older personal computer motherboards, the southbridge is one of the two chips in the core logic chipset, handling many of a computer's input/output functions. The other component of the chipset is the northbridge, which generally handles high speed onboard communications.
It provides a path between an Intel processor and an Intel southbridge on a computer motherboard which carries display data from the graphics controller (North Display) of the Intel processor package to the display connectors attached at some PCH (South Display) versions.
On some motherboards, a CNR slot replaced the last PCI slot, but most motherboard manufacturers engineered boards which allow the CNR and last PCI slot to share the same space. [1] With the integration of components such as Ethernet and audio into the motherboard, the CNR slot is obsolete and not found on modern PC motherboards anymore. [5]
