MOTHERBOARD TYPES AND FEATURES

A motherboard is the most complicated component in a computer. When you put together a

computer from parts, generally you start with deciding on which processor and motherboard

you will use. Everything else follows those decisions. Take a look at the details of Figure 3-1,

which shows a motherboard designed with gamers in mind. If you were shopping for a moth-

erboard for a gaming system, you’d have to compare many features among numerous boards.

Generally, you’d need to pay attention to form factor, processor sockets, chipsets, buses and

number of bus slots, and other connectors, slots, and ports. In this part of the chapter, we’ll

look at the details of each of these features so that in the future you’ll be able to read a mobo

ad with the knowledge of a pro. We’ll also look at how conﬁguration information is stored on

a motherboard and the best strategies to use when selecting a motherboard.

MOTHERBOARD FORM FACTORS

You learned about motherboard form factors in the last chapter, so we won’t repeat

that here. To summarize, recall that a motherboard form factor determines the size

of the board and its features that make it compatible with power supplies, cases,

processors, and expansion cards. The most popular motherboard form factors are

ATX, MicroATX, FlexATX, BTX, and NLX, in that order. ATX motherboards have

been around for a long time and have seen many improvements. Figure 3-1 shows an

ATX motherboard and Figure 3-2 shows a MicroATX board. A BTX motherboard is

shown in Figure 3-3. Each form factor has several sizes for motherboards which are

listed in Table 2-1 in Chapter 2. In addition to these form factors, you might encounter

the ITX form factor. It’s smaller than a MicroATX and sometimes used in home

theatre systems.
