Using the Quick Boot Feature of the BIOS
an unpleasant surprise when your computer reboots and tells you that it cannot
find any operating system. If you happen to get that message, don’t worry; you
did not just erase your operating system. Just reboot by pressing Ctrl+Alt+Delete
at the same time, go back into the BIOS settings, and make sure that you select
your hard drive as a boot device. After you have done that, your system will
be back to normal.
Another possible issue that you might encounter is just a matter of
inconvenience. After you change the boot order of the system devices so that the hard
drive is listed first, you can no longer use system restore boot discs. If
something has happened to your computer and you need to boot off of those drives
to restore your system or run diagnostics, just go back to the system BIOS and
lower or remove the hard disk from the first boot device and replace it with a
CD as needed.
Using the 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 check. On a machine that has large amounts
of RAM, this calculation can take several seconds. For example, a machine that
has 4 GB of RAM may take up to three seconds just to check the memory. On
top of the RAM counting, your computer needs to perform a few other tests to
make sure that all the hardware is working properly.
The complete version of these tests is not needed every time you boot, and you
can turn them 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 BIOSs
allow you to turn off the Memory Check only, which still saves a lot of time.
To turn on the Quick Boot feature or to turn off the Memory Check, do the
1. Enter the system BIOS by pressing F1, F2, Delete, the Enter key, or the
correct system setup key on the POST screen for your system.
2. After you are in the BIOS setup, locate the Quick Boot or Memory Check
option, as shown in Figure 13-2. Navigate with the arrow keys until the
option is highlighted.
