10. How DH-A2 Automatic Motherboard Repair Tools work?
11. Related knowledge
A motherboard consists mainly of a circuit board and various components on it.
PCB printed circuit boards are indispensable for all computer boards. It is actually bonded together by several layers of resin material, and the inside is made of copper foil. The general PCB circuit board is divided into four layers. The top and bottom two layers are signal layers. The middle two layers are the ground plane and the power layer. The ground and power layers are placed in the middle, so that the signal lines can be easily corrected. . Some boards with higher requirements can reach 6-8 layers or more.
2. North Bridge Chip
Chipset is the core component of the motherboard. It is usually divided into Northbridge and Southbridge according to the position of the motherboard. For example, Intel's i845GE chipset is 82845GE.
GMCH North Bridge chip and ICH4 (FW82801DB) South Bridge chip; and VIA
The KT400 chipset is composed of KT400 North Bridge chip and South Bridge chip such as VT8235 (also has single chip products, such as SIS630/730, etc.), in which the North Bridge chip is the main bridge, which can generally be used with different South Bridge chips to achieve Different functions and performance.
3. South Bridge Chip
The South Bridge chip is mainly used to connect with I/O devices and ISA devices, and is responsible for managing interrupts and DMA channels to make the device work more smoothly. It provides KBC (Keyboard Controller), RTC (Real Time Clock Controller), USB (Universal Serial Bus), Ultra
Support for DMA/33 (66) EIDE data transmission and ACPI (Advanced Energy Management), etc., close to the PCI slot.
4. CPU socket
The CPU socket is where the processor is installed on the motherboard. Mainstream CPU sockets mainly include Socket370 and Socket.
478, Socket 423 and Socket A several. Among them Socket370 supports PIII and new Celeron, CYRIXIII and other processors; Socket
The 423 is for the early Pentium 4 processor, while the Socket 478 is for the current mainstream Pentium 4 processor.
5. Memory slot
The memory slot is where the memory is installed on the motherboard. The current common memory slots are SDRAM memory, DDR memory slots, and other early EDO and non-mainstream RDRAM memory slots. It should be noted that different memory slots have different pins, voltages, and performance functions. Different memories cannot be used interchangeably on different memory slots. For 168 lines of SDRAM memory and 184 lines of DDR
SDRAM memory, the main difference in appearance is that there are two gaps in the SDRAM memory gold finger, and there is only one DDR SDRAM memory.
PCI (peripheral component
Interconnect) A bus that is a local bus introduced by Intel Corporation. It defines a 32-bit data bus and can be expanded to 64 bits. It provides a connection interface for graphics cards, sound cards, network cards, TV cards, MODEM and other devices. Its basic operating frequency is 33MHz and the maximum transmission rate is 132MB/s.
AGP graphics acceleration port (Accelerated Graphics
Port) is an interface for 3D accelerator cards (3D graphics cards). It is directly connected to the north bridge chip of the motherboard, and the interface allows the video processor to directly connect with the main memory of the system, avoiding a system bottleneck through a narrow bandwidth PCI bus, increasing the transmission speed of the 3D graphics data, and also reducing the memory in the case of insufficient memory. The system main memory can be called, so it has a very high transfer rate, which is not comparable to a bus such as PCI. The AGP interface can be mainly classified into AGP1X/2X/PRO/4X/8X.
The ATA interface is used to connect devices such as hard disks and optical drives. The mainstream IDE interface is ATA33/66/100/133, and ATA33 is also called Ultra.
DMA/33, a synchronous DMA protocol developed by Intel Corporation. Traditional IDE transmissions use a single side of the data trigger signal to transmit data, while Ultra.
The DMA uses both sides of the data trigger signal when transmitting data, so it has a 33MB/S transfer speed.
9. floppy drive interface
The floppy drive interface has a total of 34 pins. As the name implies, it is used to connect a floppy disk drive. Its shape is shorter than the IDE interface.
10. Power socket and motherboard power supply
The power socket mainly has two kinds of AT power sockets and ATX power sockets, and some motherboards have both sockets at the same time. AT socket applications have been eliminated for a long time. The 20-port ATX power socket adopts an anti-insertion design, which does not burn the motherboard like the AT power supply. In addition, there is usually a power supply and voltage regulator circuit of the motherboard near the power socket.
