1. What is the interruption conflict?
When you check for interruptions on your computer, you will find that multiple devices are in use for an IRQ instance. In Windows, multiple devices share an interruption, however, if more than one device sends a signal to the interrupt controller using the same interrupt number, the most common consequence is that the system is completely locked, even CTRL + ALT + DEL cannot be recovered. An example of an image is like a home with two phones together, but its ringing tone is exactly the same (sharing one interrupt). If they both sound at the same time, this will inevitably lead to confusion in which part of the phone should be answered. Interruption conflicts often occur after a new hardware device is installed or the system is reinstalled. At the same time, Windows 9x/2000/XP has fully adopted the plug-and-play technology to automatically allocate interruptions, but it cannot identify and install new hardware, automatic Allocation interruption often produces conflicts.
The most typical phenomenon of interruption conflicts is that a device stops working, which causes serious crashes. Of course, there are other phenomena that can also be determined as interruption conflicts:★The data transmitted by the device is incorrect;
★The system is often locked;
★Sound Card sounds abnormal;★The mouse does not work;★There is no obvious reason for all kinds of flaws on the display screen;★The printer prints characters that do not make any sense;★The floppy disk cannot be formatted;★Start the computer directly to enter safe mode.
Tips for fans) Sometimes a virus may cause a similar interruption conflict. Therefore, when your computer encounters any abnormal problems, you must first Use anti-virus software to check for viruses. Instance: built-in modem is the most vulnerable to interruption conflicts. Fan bow.nn "m \ go t j2i4f
If we sum up the frequent cases of interruption conflicts, we will find that the built-in modem is often the main character, mainly because the built-in modem itself has a serial port as part of the circuit, it is set to com2 by default, but there is also com2 on the motherboard. Windows will think there are two com2 ports, each with the same interruption. The solution is: after installing the built-in modem, it is best to enter the bios and disable the system's built-in com2 port. At the same time, few devices now use the COM port, therefore, you can disable COM1. 2. How to Solve the interruption conflict

First Delete "?" And "!" And then restart the device so that the computer can recognize the device again. This is because some of them have "?" And "!" The device may be a driver installation error. Reload it again to solve the problem. Fans blog 6w' X. B0] Q # V ^ Z
If the above step still cannot solve the problem, most of the problems are interrupted conflicts. You can only manually adjust them to solve the interruption conflict. In Device Manager, double-click the faulty hardware item to go to the "Resources" tab and check whether there is a conflict. If yes, cancel "use automatic settings ", next, select the "interrupt request" item in the list above, and then press the "change settings" button to bring up the "Edit interrupt request" window, where the interrupt is changed to an idle interrupt number. 1 {8fh * ey5' & @ fxz. r5f n03. how to prevent interruption conflicts

E + a8g & E (a "mkbb) M0 do not install all boards in the system once. At first, only the minimum configuration such as the video card, memory, hard disk, floppy disk, and optical drive should be installed, and then windows should be installed. If the motherboard contains a dedicated driver, after Windows installation is complete, install now. That is to say, you need to complete the configuration of all the built-in devices before installing all other boards or expansion devices. This effectively reduces interruption conflicts. Fan Bo.

After the system configuration (together with installing the Windows Update patch) is complete, you can add a device, install its driver, and configure it at a time in a specific order. The correct sequence should be: Sound Card → built-in or external modem → Nic → scsi → other boards or devices.

LC n xf2h0ni0A foreign senior expert said that the sound card should be loaded into the system before any board except the video card. Even if a device conflicts with the sound card, it must change the interruption of other boards or equipment, try not to change the interruption of the sound card, because many sound support software does not support non-default configuration of the sound card.

Restart and enter the system bios. Disable some unused ports and options according to the actual situation. Here we will use a large number of Award bios as an example. For other bios, refer to the motherboard manual.

★If you want to use an external modem and want it to be faster, The PS2 mouse is the same fashion, it is best to connect the modem to COM1/com3 (irq4 ), disable com2/com4 (irq3) in BIOS. Fans: cj9m \ @. m0b! '
★USB device: the biggest advantage of USB is that the USB bus only uses one interrupt, regardless of the number of devices connected to it (up to 127 ), this means that you can automatically delete or add devices on USB without worrying about resource depletion or resource conflict. Fan bow.vdud QP {
★IRQ 0 ~ 8 is mainly used for low-speed old devices, such as 16-bit sound cards and 8-bit MODEM. Therefore, it is best to ensure that most of the current devices use IRQ 9 or above. Instance: to speed up your printer or device connected to the parallel port}. T/yta hh-y
In Windows 2000, if the device connected to the parallel port runs fast, you can use this technique to improve its performance and response speed.
Sci4} 9xseq0 go to "Device Manager", double-click the hardware list to expand "port (COM and LPT)", and then double-click "Printer Port (LPT1 )", go to the "Port Settings" tab. the default option for Windows 2000 is "Do not use interrupt". However, if an interrupt is assigned to the port, it can greatly provide the performance of the port to connect to the device. If you are sure that there are idle interruptions in the current system, we recommend that you select "use any interruptions assigned to this port ". If you are not sure whether there are unused interruptions, you can choose "do not use interruptions as much as possible" (If your device indicates that there is no need to interrupt, this technique is not applicable ).
