|
|
|
In essence, the boot up process simply contains a small bit of code that is permanent to the personal computer. The boot up process only has two main components, even though it is required for any computer to work properly. The first is to run the power on self test, and the second is to search the computer for drives, properly called the disk boot. The reason that computers don’t just integrate the operating system into the boot up process, or the boot up process into the operating system, is twofold. ... But the operating system would never function correctly, in fact it never even starts, if the boot up process is unsuccessful.
The first part of the boot up process is the power on self test, or POST, which begins as soon as you press the ON button for your computer. ... If you look at your monitor this is the first time you would be seeing anything, which shows you how fast this process actually occurs because visually the second you hit the power button is the second that you see something on your screen. ...
The next part of the boot up process is quite important, because it sends signals over the floppy and hard disk drives to determine which, if any, drives are available. ...
This step is called the disk boot. The first step is to check drive A for a floppy disk and check if it has any system files that need to be given to the disk boot.
