1. Install the motherboard: first open the chassis and remove the side cover. Align the I/O port of the motherboard with the back of the chassis, align the positioning hole of the motherboard with the motherboard bracket on the chassis, and fix the motherboard with bolts.
2. Installing cpu: First, gently push the handle beside the motherboard socket outward, then pull the handle upward to the vertical position, and insert the first pin (pin with hole) of cpu into cpu. It should be noted that the fillet should be aligned and inserted to prevent damage, the guard plate should be pressed back, and the handle should be clamped and fixed.
Know three kinds of jumpers and switches of CPU on the motherboard,
The first step is to confirm the CPU type. Such as Intel or AMD or Cyrix.
The second step is to know the working voltage of CPU. Common working voltages of CPU are 2.0, 2.8V, 2.9V, 3.3V, etc. In general, the set voltage should be consistent with the working voltage of CPU. If the set voltage is too high, it may burn out due to overheating of CPU; Similarly, low voltage can also lead to functional failure.
Step 3, set the CPU frequency. This step is a little more complicated, but the setting method of each CPU is the same.
Step 4: Set frequency doubling.
3. Install the fan: install the fan on the cpu, hang the low elastic hook of the fan on the hooks at both ends of the socket, and insert the three-hole power plug of the fan into the fan power socket of the motherboard (generally close to the cpu).
4. Install the memory stick: The notch on the memory stick is aligned with the notch of the memory stick slot on the motherboard, and it is pressed vertically downward into the slot, and the white fixing clips on both sides of the slot automatically snap upward to lock the memory stick.
5. Install the power supply: put the power supply on the chassis, and the fan of the power supply should retreat towards the chassis and aim at the fan hole. Secure the power supply with bolts. The connection point originates from the motherboard (the motherboard power interface is generally near the cpu)
1)AT power supply is connected to the motherboard with two six-core plugs. Connect the two groups of wires P8 and P9 with the power connector on the motherboard, and pay attention to the black lines in the two groups of wires, otherwise it will cause serious consequences.
2) Connect the fan power cord. The motherboard does not have a jumper to connect the fan, or the CPU fan is purchased separately, so the power supply of the fan needs to be connected to the power supply of the host. The direction of this power connector is fixed. If the direction is opposite, it cannot be installed.
6. Installation of hard disk: First, fix the hard disk in the host bracket (the label is upward and the wiring part faces the inside of the chassis) and fix it with bolts. Then, connect the D-type four-hole plug of the power supply with the power socket of the hard disk. Use one end of IDE data cable to connect to the hard disk. Note: the 1 line of the data cable (1 line/colored line represents the first line of the whole data cable) is aligned with the first pin of the hard disk (the side near the power socket corresponds to the colored line inward of the power cable). Connect the other end of the data cable with the IDE interface of the motherboard, and align the data cable with the first pin of the IDE interface. The IDE excuse and its first foot are marked on the motherboard.
(Pay attention to setting the master and slave disks of CD-ROM drive and hard disk, and make clear their relationship. How to set the master-slave disk can refer to the parameter table on the IDE device. )
7. Installation of floppy disk: The installation method is the same as that of hard disk. The tail port of the data line is connected with the floppy drive interface of the motherboard, and the 1 line of the data line is aligned with the first pin of the interface. Insert the small four-hole plug of the power supply into the power plug of the floppy drive.
A) distinguish terminals a, b and c of floppy drive data line. One end where the data lines intersect is end A, the middle end is called end B, and the other end is end C.. Part A and Part B each have a connector for connecting a 3-inch floppy drive. Part C is connected to the floppy drive interface on the motherboard. When connecting two floppy drives, connect one floppy drive in area A and one floppy drive in area B. At this time, the floppy drive connected in section A is physically disk A and the other is disk B; When only one floppy drive is connected, connect it to Part A..
B) When connecting one end of the motherboard, make the red edge correspond to the 1 speaker of the interface. At present, a plastic card slot is added to the interface on the motherboard, so it can't be inserted in the wrong direction. The same is true for floppy drives. The red side corresponds to the horn of 1. Press hard.
8. Install the optical drive: the installation method is the same as that of the hard disk. The tail port of the data cable is connected with the optical drive interface of the motherboard, and the 1 line of the data cable is aligned with the first pin of the interface. Insert the small four-hole plug of the power supply into the power plug of the optical drive.
9. Connect the serial port line of AT motherboard
Ordinary AT motherboards also connect serial lines and parallel lines to the motherboard, and ATX motherboards are directly attached to the motherboard, which can save this step.
A) Find out the standards of serial and parallel lines on the motherboard, their corresponding positions and their positioning angles (the position of the first needle corresponding to the red line).
B) Connect the serial port and parallel cable of the At motherboard: the serial cable connects two 9-pin serial ports on the motherboard, next to COM 1 and COM 2；; The parallel cable is connected to the 25-pin parallel port on the motherboard and marked with LPT next to it. When connecting, keep the red edge of the data cable corresponding to the 1 speaker of the interface, and then press the connector to the bottom.
10. Installing the graphics card: find a Conde PCI slot, insert the interface of the graphics card into the slot toward the back of the chassis, and fix the graphics card on the chassis.
1 1. Install the sound card: find a Conde PCI slot, insert the interface of the sound card into the slot toward the back of the chassis, and fix the sound card on the chassis.
12. Installing the network card: find a Conde PCI slot, insert the interface of the network card into the slot towards the back of the chassis, and fix the network card on the chassis.
13. Connect the control panel: First, find the connection position of the indicator light and the key on the chassis panel on the motherboard (generally metal pins), and then connect the HDD LED, TB SW, TB LED, Reset, speaker and PowerLED on the chassis panel on the motherboard pin according to the principle of "positive connection and negative connection".
A) connection of switch wires. The chassis with ATX structure has a main power switch connection, which is a two-core plug. Like the connector of Reset, it is short-circuited when pressed and open-circuited when released. Press the computer's main power on once, and then press the power off again. However, you can also set it in the BIOS, and you must press the power switch for more than 4 seconds to turn it off, or you can only turn it off by software at all.
B) Dual-core connector for hard disk indicator light, and the line 1 is red. On the motherboard, such pins are usually marked with the words IDE LED or HD LED, and the red line pair is 1 when connected. When this line is connected, the hard disk light on the chassis will light up when the computer reads and writes the hard disk. It should be noted that this indicator light can only indicate IDE hard disk, not SCSI hard disk.
C) The three-core plug is the wiring of the power indicator light, using 1 and 3 digits, and the 1 line is usually green. On the motherboard, pins are usually labeled as power supplies. When connecting, note that the green line corresponds to the first pin (+). When the computer is connected, the power light is always on as soon as it is turned on, indicating that the power has been turned on.
D) The dual-core connector is connected to the reset key of the chassis and to the reset pin on the motherboard. The reset pin on the motherboard works like this: when there is a short circuit, the computer restarts. The reset key is a switch. When pressed, it will produce a short circuit, and when the hand is released, it will restore the open circuit. Instantaneous short circuit can restart the computer. Occasionally press the reset button to release it, but it doesn't pop up. It has been short-circuited and the computer has been restarted.
E) The four-core plug of e)PC speakers actually has only two wires, 1 and 4. The 1 line is generally red and should be connected to the speaker pin of the motherboard. This is marked on the motherboard, usually a speaker. When connecting, pay attention to the red line position corresponding to 1.
14. Seal the remaining notches with baffles. Then carefully check the connection of each part, and then turn on the power to observe the operation of the computer. Run ok, cover the chassis and install the screws, so that the installation process of the host is basically completed.
15. Plug in the mouse and keyboard.
16.CMOS settings
My approach is to load the bios factory settings first, and then load the bios optimization settings. Then enter STABDRAD cmos settings (standard cmos settings), modify the system date and time, and then set the hard disk and floppy disk to automatic. Turn off display settings and error pause settings.
17.bios settings
My approach is: enter the advanced bios function, because the optimized bios settings have just been loaded, the virus advertisement has been turned off, and the secondary cache of 1.2 has been turned on ~ ~ Other, by default, no problem. Then we'll start with the optical drive. We started the following steps.
18. hard disk partition and formatting
Partition and format hard disk with FDISK
Create a DOS partition or logical partition
1) Start the computer with the startup CD or floppy disk. Generally, there are partition commands of FDISK in the boot CD or floppy disk. If not, please copy it to a floppy disk from other places and run the FDISK command.
2) establish a main DOS partition
The default option is "1". If your hard disk is not partitioned, just press Enter. Then, in the dialog box shown below, select Create Primary Partition, select 1, and press Enter. At this point, you will be asked whether to use the largest available space as the primary partition. The default answer is "Y", you just need to press Enter directly. Of course, when the program asks you if you want to use the maximum available space as the main partition, you can also answer "n" and press enter. At this point, you will be asked to Enter the size of the primary partition, and then press Enter. At this point, the system will automatically assign the logical drive letter "C" to the primary partition. Then the screen will prompt that the main partition has been established and display the ratio of the main partition capacity to the total hard disk capacity, and then press the "Esc" key to return to the FDISK main menu.
3) establish an extended partition
In the main menu of FDISK, continue to select "1" to enter the "Create Partition Menu", and then select "2" to create an extended partition. The screen will prompt that the current hard disk can be built to expand the full capacity of the partition. At this point, if we don't need to reserve partitions for other operating systems (such as NT, LINUX, etc.). ), we recommend using all the hard disk space provided by the system. At this time, we can directly press Enter to create an extended partition, and then the screen will display the capacity of the established extended partition.
4) establishing logical partition
After the extended partition is established, the system prompts the user that the logical drive has not been established. At this time, press the "Esc" key to start setting up the logical disk, prompting the user to create all hard disk space for the logical disk. Users can set the number of logical disks and the capacity of each logical disk according to the hard disk capacity and their own needs. After setting, the screen will display the number and capacity of logical disks created by users, and then return to the main menu of FDISK. Set the number and capacity of logical disks.
5) Activate the main partition of the hard disk.
When both the main partition and the extended partition are built on the hard disk, the main partition must be activated, otherwise the hard disk cannot boot the system in the future. Select "2" on the FDISK main menu (set active partition). At this time, all partitions on the main hard disk will be displayed for users to choose. Our main disk only has the main partition "1" and the extended partition "2". Of course, we choose the main partition "1" to activate, and then return to the FDISK main menu.
6) exit the FDISK main program.
Exit the FDISK program. Continue to press the "Esc" key to exit the screen and prompt the user to restart the system.
7) After starting the system with the startup disk, run Format format command to format the hard disk partition, and run format c: /s, where the /s parameter indicates formatting the system disk.
