After the boot into the XP system is always a long and large hard drive self-test.
The first thought is that the BIOS settings should be modified to skip the self-test program.
The method is to press the DEL key to enter the BIOS setup after the boot, then select "Standards BIOS Setup", and then find the "Quick Test" setting, set its value to Enabled, save settings exit. However, after entering the BIOS, the "Quick Test" Settings item has been set to Enabled.
From the search also learned that you can modify the registry method to skip the large set of self-test, and decided to try. The method is "Start → run", enter "regedit" in the Run dialog box, open Registry Editor, and select "Hkey_local_machinesystemcurrentcontrolset controlsession Manager" in turn subkey, then locate the "BootExecute" key value entry in the right window and empty the value, and then press the "F5" key to refresh the registry.
But when you go to the registry and choose to Session Manager, you find that there are a lot of options, and it's hard to find the "BootExecute" key. Then open "Edit" in Registry Editor-find, enter "BootExecute" in the input field, and then look for it, and sure enough to find the "BootExecute" key. Double-click the "BootExecute" key and found that the "Value data" column is sure there is a string of English letters (do not remember the specific content). Clear it, press F5 to refresh the registry.
Quit Registry Editor, reboot the computer, the self-test disappears, it's done, haha!
