1. When you turn on your computer, the power supply distributes current to the motherboard and the other devices located in the system unit case.
2. The surge of electricity causes the CPU chip to reset itself and look to the BIOS chip for instructions on how to proceed. BIOS stands for Basic Input/Output System. The BIOS is a set of instructions that provides the interface between the operating system and the hardware devices. The BIOS is stored in a read-only memory (ROM) chip.
3. The BIOS chip begins a set of tests to make sure the equipment is working correctly. The tests are completed, the BIOS instructions are copied into memory where they can be executed faster than in ROM.
4. After the POST tests are successfully completed, the BIOS begins looking for the operating system. Usually, it first looks in diskette drive A. If an operating system disk is not loaded in drive A, the BIOS looks on drive C, the drive letter usually given to the first hard drive.
5. When the BIOS finds operating system, it begins loading the resident portion into memory. For personal computers using a verion of DOS, the resident portion is called the DOS kernel.
6. The kernal then loads system configuration information. The configuration information is contained in a file called CONFIG.SYS. This file tells the computer what devices you are using, such as a mouse, a CD-ROM, a scanner, or other devices. For each of these davices, a device driver program is usually loaded. Device drive program tell the computer how to communicate with a device.
7. The kernal loads the command language interpreter. On DOS computers, the command language interpreter is called COMMAND.COM.
8. COMMAND.COM loads a batch file named AUTOEXEC.BAT that performs optional tasks such as telling the system where to look for files (PATH command) and loading programs that you want to run every time you turn on your system, such as certain urility programs.
9. If you havn't specified that the computer immediately start a particular application program, the system displays a command language prompt that indicates the system is ready to accept a command from the user. If you always want a particular application program to automatically start during the boot process, such as a word processing program or Microsoft Windows, you include the name of the program as the last line in the AUTOEXEC.BAT file.
