Break the conflict to cause the flash disk to not use the remedy

Although the size of the current data is increasing, the flash disk is limited by its capacity can not meet the needs of people, more friends in the purchase of mobile storage devices to choose the mobile hard drive. But because of the smaller size, its portability is better, and cheap prices, still favored by a large number of users, so the market space is still very large.

Flash disk is easy to use, for the current Windows XP system, without the installation of driver software can be recognized and used, but used in older machines, you have to install the driver, and in the use of such or such a problem, this is not, The author's 64M flash drive is a problem when used on a friend's old machine.

A few days ago, the author in a friend of the older machine to prepare a copy of a few drivers on a few driver encountered such a failure: The friend's computer is an assembly machine, with 6 years, can be considered an antique. The specific configuration of the computer is very old LX motherboards with the Intel Celeron 266MHz processor, SIS6326 graphics, 10GB hard drives, with 2 USB connectors. The Win98 se operating system used.

The author inserted the Flash disk into the USB interface, the system immediately found a new USB device, and then the author of the flash drive driver in the CD-ROM drive, start installing the flash drive driver. The installation was a smooth process, but after restarting the computer, I can't find the drive letter in the data manager, and I can't find it in My computer.

Because this computer for a long time did not use, so I suspect that the computer's USB interface in excess of dust, resulting in poor contact reasons. Then found a clean tool, the computer's USB interface clean up, reinsert the flash drive, when the red light of the flash drive began flashing, which indicates that the flash drive has been properly connected with the computer. But when I turned on my computer, I could not find the drive letter of the flash drive, nor did I find the flash drive in the explorer.

I think, may be caused by the hard disk conflict, so open the resource manager, found that each hardware set before the yellow exclamation point, which means that all the hard disk devices in this computer is not a conflict of the problem, then where is the problem? So the author again installed the flash drive driver, The problem is still unresolved.

The author once used in some old machine on this flash drive, can be used normally, in this machine should also have no problem. So I think there may be a problem with the flash drive, in order to verify the flash drive, the author will be inserted into the latest computer flash drive, the results of the flash drive is quickly recognized, all normal, which fully excludes the flash disk failure.

The difference between other old computers is that there are no built-in adjustment solutions installed in the other computers, and the computer has a built-in modem for the ESS, will that be the problem? So the author in the resource manager carefully checked the built-in modem, did not find a yellow exclamation mark, However, when the author chose to "View the device by connection", and then click "Computer" to show all IRQ interrupts, but found that the original ESS built-in modem and USB devices are used to interrupt 10, this is finally found the problem lies, and sure enough USB device and modem there is a conflict. This apparent interruption of conflict is "blind to the eye" for Windows systems. Reason to find, and then should be a good solution to this problem.

In fact, the solution is very simple, open the chassis, the built-in modem from the PCI slot to take down, reboot and insert a USB flash drive, the flash drive can be used normally. But every time using a USB flash drive can not take down the modem, it is too troublesome. As a result, the author inserts the modem into another PCI slot, then enters the motherboard's BIOS setup, modifies the "Pnp/pci CONFIGURATION" setting, and sets the "PNP Osinstall" to "yes", " Controlled "set to" Auto ", after this setting, when using a Plug and Play operating system such as WIN98, the system can automatically assign interrupts to all devices to avoid conflicts. Restart your computer after you save the settings, the author of the Flash drive is still plugged into the USB interface did not take down, the system after the reboot immediately found in the motherboard on the flash drive, and automatically installed the modem driver, again after the restart, and then look at the interruption of two, the modem use of the interruption of 7, and the flash drive uses the interrupt 10, this time the author uses the modem to have no question, certainly again uses the external USB device, also does not appear any question.

Fault summary: Like this flash and modem conflict is relatively rare, because USB devices are generally used by high-end interrupts, and the built-in modem is generally used by the low-end of the interruption, such as this situation because the modem use of high-end interruption to cause such a fault, The way to solve the problem is, of course, to reset the new interrupt for the modem, we generally change the motherboard BIOS settings can be achieved.
