Driver is a basis for us to use the operating system, without it, we can not hear the sound, can not see the picture, on the net. Let's take a look at common drive failure solutions, detailed explanation, simple operation.
First, the basic knowledge: how to implement the Device Manager problem symbol.
1, the Red Fork number
The hardware devices in the "IEEE 1394 bus Master" and "PCMCIA Cards" show a red fork in the previous Diagram window, wh
these services in previous versions. To manually modify a number of parameters;
8 In addition, the support of PCMCIA devices is enhanced, which is very important for users who use PCMCIA devices for laptops;
9 in the security aspects of a lot of repair work, the security default settings to ensure that the port is closed, the new firewall screen can be used to open or close the user arbitrarily;

computer card, which is used to connect to the LAN. It is only a signal to send and receive equipment, only in the Internet to find the export to achieve the connection with the Internet, all wireless network card can only be limited to the scope of the wireless LAN has been installed. Wireless network card is not through the wired connection, the use of wireless signal to connect the network card.
Wireless card can be differentiated according to different types of interface, the first is the
The meaning of the problem symbol in Device Manager and how to fix it:
1. Equipment management where the Red Cross number
When the hardware device in the IEEE 1394 bus Master and PCMCIA card displays a red fork, this means that the device has been deactivated, in fact because the laptop does not frequently use 1394 devices and PCMCIA cards, from saving system resources and increasing startup speed.

First, the benefits of unlocking the hard drive AHCI mode:
1. Hard drive AHCI mode can greatly shorten the hard disk search times and shorten the data lookup time, so that the disk under multitasking can be used efficiently. Greatly improve the efficiency of frequent read and write hard drive programs, especially when running a large game or software, the speed of reading and writing has been significantly improved.
2. Can reduce the temperature of the hard drive, read the noise when the disk.
, PCMCIA Plug-in card modem
Plug-card modem is mainly used for laptops, small size. With mobile phone, can easily realize mobile office.
4, Frame-type modem
A rack modem is the equivalent of concentrating a set of modems in a box or enclosure and powering them with a unified power supply. Rack-type modem is mainly used for Internet/intranet, Telecommunications Bureau, Campus network, financial institutions, such as the center of the network room.
the region's signal radiation intensity, but must choose famous brand manufacturers of products, some of the products do not play a real role, in the form of a dummy.
In addition, you can turn on 54Mbps mode. Some wireless ap/routers to "compatible" with more wireless network cards, does not turn on its G mode, we can set "wireless mode" to Gmode (g mode), the "Transfer (TX) rate" set to 54Mbps, activate 8X mode, and "Antenna transmission power" set to the highest, In order to speed up the tra
computer;
Step three: Restart the computer will enter the WIN7 system, in the Device Manager in the PCMCIA adapter under the Texas Instruments PCI-1510 CardBus Controller Right click on the update driver, select
Fourth step: After restarting the computer, AHCI mode is turned on.
Finally, the way to open the hard disk AHCI mode when installing the system:
First, the BIOS on the motherboard will have AHCI enabled, which is to adjust the hard drive
network cards, does not open its G mode, at this time to log on to the ap/router, its "wireless mode" set to G mode (G model), the "Transfer (TX) rate" set to 54Mbps, activate 8X mode, and the "Antenna transmission power" Set to the highest.
We had better not use Windows XP Wireless management, but install the network card with the program, this setting, there will be more options, display is the author of the network card with the program settings, which has the corresponding 8X mode, and can
Use of wireless network card
One, the classification of wireless network card
Wireless card can be divided into: built-in wireless network card and external wireless network card.

Built-in wireless card is divided into two types: a desktop-specific PCI interface wireless network card. (Figure I) a MINI-PCI wireless network card that is built into a notebook computer. (Figure II)
