When the computer boots to the verifying DMI Pool data solution:

DMI is the abbreviation for the English word desktop Management interface, the desktop management interface, which contains configuration information about the system's hardware. The computer verifies the DMI data each time it is started, and if the data is faulty or the hardware changes, the machine is detected and the test data is written to the BIOS chip for preservation. So if we disable the BIOS chip refresh feature in the BIOS setup or use jumpers on the motherboard to disable the BIOS chip refresh, the DMI data for this machine will not be updated. If you change your hardware configuration, the machine still works as the old system configures when you are working on the Windows system. This will not give full play to the performance of the newly added hardware, and sometimes this or that can happen.

If we start the computer to see this information, the system for a long time to stop before or in the panic state, for machines such failures are generally difficult to deal with. We can check the system log and other files for analysis because it can't be a problem after entering the system. However, according to the process principle analysis of PC startup, this message usually has the following possible situations:

1. Hardware changes

When the hardware configuration of the host changes, but we are using the post function, at this point, the system can not identify the new hardware added, will be the old configuration to work, at this time will be able to power up after the power-on, but there is no normal start "beep", while the monitor also has no image display, only the sound of fan rotation.

Another reason is that the compatibility of the newly added hardware is not good enough to cause the above situation to occur.

2.BIOS Settings Change

When the BIOS setup error, such as the memory of the read and write parameters set incorrectly, the hard drive mode settings, the onboard sound card and integrated sound card settings, etc., will cause the normal start.

3. Hard Drive Cable Connection error

This kind of situation has the hard drive data line contact is bad, the data line quality inferior causes the data number to lose the error too many, the data line socket is incorrect (connect the board end and the hard disk end to fall the height), the master and slave hard disk jumper is incorrect, the hard disk capacity or the mode set

4. Hard drive main boot area content is corrupted

When the contents of the main boot area of the hard disk are overwritten by other programs or destroyed by the virus, the hard disk partition table may be purged or set to the logical lock state, and then it will be frozen at this time.

For the boot of the hard drive's boot zone to be compromised, we can fix it using the FDISK/MBR command, or use the KV3000 disk editing feature to find out if the other 62 sectors on the 0 0 side have a backup master boot program, restore it to 0 0-side 0.

The damage to the partition table is more cumbersome. If only the partition table does not have a "80" flag or multiple "80" flags, or no "55AA" flag, we can only use the KV3000 disk editing function to manually fix it. If it is a logical lock, you need to make a special disk to unlock it. If the partition table is completely corrupted or encrypted, we can only repartition it.

5. Hard drive is faulty

Now the size of the hard drive is getting bigger and faster, but the quality of the hard drive seems to be getting worse. To the current market there are still 94, 95 production of hundreds of m of second-hand hard drive in the sale. But now, just bought a new hard drive, not a few days will be bad way into pieces or inexplicable wonderful loss of data, no longer is the "rattle" of the advice to strike out. When the hard disk hardware failure, it will also appear above, such problems in the CMOS hard disk can recognize the hard disk, the dial is very smooth, but is not in the system, can not be normal partition and format.

6. Problems with the motherboard

Related to the motherboard is also mainly the motherboard's hard disk controller, resulting in data transmission instability, error rate is too high.

7. The damage caused by overclocking

If we overclocking too much, will also appear after the boot to the hard drive here on the panic. At this point we'd better live the frequency of the CPU displayed at post, then open the chassis to check the actual CPU frequency is how much, whether the two are the same. Especially for the CPU after the PIV, its integration is extremely high, if we use overclocking, it is very likely that the internal CPU within a short period of time the excessive attenuation, resulting in a short CPU time to scrap.

Way to solve:

1. Restore the state of the hardware before it changes, and check to see if the system starts properly.

2. Check that all connectors or expansion cards are properly connected.

3. Try reconfiguring the "PNP/PCI configuration" "Reset Configuration Data" in the BIOS to be set to "Enabled" using the BIOS options such as "Force Update ESCD", and then save the disk exit. If you can not start, try to set the "Disabled" to try.

4. Check the motherboard manual for CMOS jumper information and clear the CMOS. Please note that when you clear the CMOS settings, you must unplug the host power cable or set the host power switch to off or 0.

5. Disconnect the hard drive connector, including the optical drive or other IDE devices, and then enter the BIOS settings select the boot sequence for floppy disk startup, press F10 store to exit, and then put a bootable system disk in the floppy drive to check if the system can start properly.

6. After clearing the CMOS settings, set the "PNP/PCI Configuration" option in the CMOS settings to "Enabled", restarting the computer again to update the set DMI data, also known as forcing the update of the ESCD data.

7. If the host can boot through a floppy disk, but can not boot through the hard drive, this situation may be the hard drive of the main boot area of the data is damaged, you can use the partition software to repair the main boot zone program code, such as using a floppy disk to start the computer, use the FDISK/MBR command to Also can go to the corresponding hard disk manufacturer's website to download special hard disk Analysis tool program, to check their own hard drive specific fault.

8. If you can not troubleshoot the failure after the above settings, you should consider the motherboard or hard disk IDE interface problem, you can use the replacement method to resolve.
