主板技术参数（Mainboard technical parameter） The Beiqiao chip is responsible for data exchange and transmission between the CPU and memory, so he directly determines what kind of CPU and memory the motherboard can support. In addition, Beiqiao chip is also responsible for the control, management and transmission of AGP bus or PCI-E16X. In general, Beiqiao chips are primarily used to connect devices with high data rate devices The south bridge chip is responsible for communicating with low rate transmission devices. Specifically, responsible for USB equipment, onboard sound card, network card, PATA equipment, SATA equipment, PCI bus equipment, equipment, equipment, serial parallel RAID architecture and external wireless devices, communication, management and transmission work. Of course, the south bridge chip is unlikely to achieve so many functions on its own. He needs to work with other functional chips to allow all low speed devices to function properly. Tip: the two blocks across the AGP slot are the north and South Bridge chips, the South Bridge is located above the PCI slot, and the CPU chip next to the slot is covered by the heat sink Because the CPU FSB continues to improve, other equipment can not afford such a high frequency, so there was a division. Frequency technology is through the Beiqiao CPU chip motherboard FSB is reduced, and then provided to the card, hard disk and other equipment. In the early days of the 66MHz FSB era, PCI equipment is 2 frequency, AGP frequency of 100MHz equipment; then the FSB era is PCI equipment AGP equipment 3 frequency, frequency 2/3 (Beiqiao chip some 100MHz also supports PCI 4 frequency equipment); Beiqiao chip currently generally support the 133MHz FSB, namely PCI, 4 frequency equipment AGP equipment 2 frequency, and so on. In short, in the standard (66MHz, 100MHz133MHz, 200MHz FSB), Beiqiao chip through frequency division technology of PCI equipment in the 33MHz, AGP equipment in 66MHz. BIOS is the abbreviation of Basic Input/
