ISA Expansion Slots If you have a computer made before 1997, chances are the motherboard has a few Industry Standard Architecture (ISA) expansion slots. They’re easily recognizable, because they are usually black and have two parts: one shorter and one longer. Computers made after 1997 generally include a few ISA slots for backward compatibility with old expansion cards (although most computers are phasing them out in favor of PCI).

3 volts or 5 volts). You must set the motherboard to provide the correct voltage for the processor it is using. You do so by changing a setting on the motherboard with either a jumper or a DIP switch. 35 shows both a jumper set and DIP switches. Motherboards often have either several jumpers or one bank of DIP switches. Individual jumpers are often labeled with the moniker JPx (where x is the number of the jumper). 35 Jumpers and DIP switches Jumper “Rocker-type” DIP switch “Slide-type” DIP switch Many of the motherboard settings that were set using jumpers and dip switches are now either automatically detected or set manually in the CMOS setup program.

This is the olive green or brown circuit board that lines the bottom of the computer. It is the most important component in the computer because it connects all the other components of a PC together. 14 shows a typical PC system board, as seen from above. All other components are attached on this sheet. On the system board, you will find the Central Processing Unit (CPU), underlying circuitry, expansion slots, video components, random access memory (RAM) slots, and a variety of other chips. 14 A typical system board Types of System Boards There are two major types of system boards: integrated and nonintegrated: Nonintegrated system board Each major assembly is installed in the computer as an expansion card.
