If the boot block detects any corruption in the main BIOS, it will typically warn the user that a recovery process must be initiated by booting from removable media (floppy, CD or USB flash drive) so the user can try flashing the BIOS again. Some motherboards have a backup BIOS (sometimes referred to as DualBIOS boards) to recover from BIOS ...
Most motherboards have connectors for additional computer fans and integrated temperature sensors to detect motherboard and CPU temperatures and controllable fan connectors which the BIOS or operating system can use to regulate fan speed. [5] Alternatively computers can use a water cooling system instead of many fans.
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).
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.
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.
A system designer should work with their memory and BIOS vendors to implement a suitable SPD programming. As such, the MRC is a part of the BIOS (or firmware) of an Intel motherboard. George Chen, a research and development (R&D) director at ASUS, described it in 2007 as follows: [1]
AMIBIOS (also written as AMI BIOS) is the IBM PC-compatible BIOS that was formerly developed and sold by American Megatrends since 1986. [10] In 1994, the company claimed that 75% of PC clones used AMIBIOS. [16] It is used on motherboards made by AMI and by other companies. [3] A chip containing an old version AMIBIOS image, pulled from an ECS ...
This method can also be integrated into a Windows installation disk to activate on initial boot. Another method consists of modding the BIOS to insert the SLP 2.1-2.5 table, which can be used to replace blacklisted keys, or to add the SLP table to motherboards that do not have it (such as Gigabyte).
