Using Quick Boot Feature of the BIOS

All systems initialize in more or less the same way. During the POST mentioned earlier, the BIOS checks the hardware devices and counts the system memory. Out of all the different types of system memory, the random access memory, better known as RAM, takes the longest to be checked. Checking the RAM takes time, and on a machine that has large amounts of RAM, this calculation can take several seconds. For example, a machine that has 512MB of RAM may take up to three seconds just to check the memory. On top of the RAM counting, a few other tests need to be done because your computer wants to make sure that all the hardware in your computer is working properly.

The complete version of these tests is not needed every time you boot and can be turned off to save time. Most system BIOSs offer a feature called Quick Boot. This feature enables the user to turn off the full version of the test and sometimes enables you to run a shorter quick check test instead. Other BIOSes allow you to turn off the Memory Check only, which will still cut down on a lot of time.

To turn on the Quick Boot feature or to turn off the Memory Check, just do the following:

1. Enter the system BIOS again by pressing F1, F2, or the correct system setup Enter key on the POST screen for your system.
2. After you are in the BIOS setup, locate the text "Quick Boot" or "Memory Check". Navigate with the arrow keys until the option is highlighted.
3. Use the Change Value keys to cycle through the options and select Enable for the Quick Boot feature or Disable if your system's BIOS has the Memory Check feature.
4. After you have made the change to the setting, exit the system BIOS by pressing the Escape key. Make sure you save the changes upon exit.

Use of the Quick Boot feature or the disabling of the Memory Check will not do any harm to your system. In fact, some computer manufactures even ship their computers with these settings already optimized for performance. The only downside to disabling the tests is in the rare situation in which your RAM self-destructs; the BIOS will not catch it, and you might receive errors from the operating system or your system could become unstable. If you notice that your system becomes unstable and crashes frequently or will not even boot, go back into the BIOS and re-enable the tests to find out whether your system's memory is causing the problems.
