After assembling your computer, you'll need to install an operating system, which is really just a software procedure. It's common to talk about "installing" software, even though it only involves inserting CDs into the CD drive as required. Your PC will be fully assembled before we install software.
We'll take you through installing an operating system step-by-step in detail in another chapter. You may also want to examine and/or modify your system's BIOS, which we'll discuss later. Many times, you'll be able to get your PC up and running adequately without tinkering with the mainboard's BIOS at all. But, tweaking the BIOS may enhance your system's performance. Make changes to BIOS very carefully.
For example, if you update your mainboard's BIOS with Flash BIOS and your computer hangs, it's possible your PC will no longer boot at all. We'll also discuss partitioning and formatting a hard drive. But, first, we need to get our parts together.
