Day 21 Agenda
1. Electricity team contest
2. Inspect CMOS settings for Power Management See A+ in Depth, p. 168-170
Complete Meyers Labs
6.1: On an ATX system, see if you can trace the wire running from the power switch on the
front panel to a jumper on the motherboard. (Read part b, but don't use a screw driver to
connect the two jumpers, as Meyers suggests.)
6.2: Be sure your multimeter is set to measure AC voltage, as shown on Meyers, p. 73.
Carefully measure the three AC voltage settings that Meyers describes on p. 72-74
and record your readings
Hot to neutral ______________
Neutral to ground ___________
Hot to ground _____________
We don't need to repeat the measurements of the DC motherboard voltage in the Meyers lab.
Time permitting, Alonzo may show us how to measure resistance with the Ohm setting on the multimeter
2.1 We're beginning our study of the Motherboard chapter by identifying CPUs.
1. Look at the chips in the picture on p.15 of the Meyers lab manual. Compare them to the chips in your computer.
Note any differences you see: ________________________________________________________
3. Identify the type of fan used by your CPU (with hinge/without hinge/screw down)
5. Use Internet resources to fill in the following tables
CPU External Data Bus Bits Address Bus Bits Intel 8086 Intel 80286 Intel 80386DX Intel 80386SX AMD AM386DX AMD AM386SX Intel 80486DX AMD AM486DX Intel Pentium I AMD K5 AMD K6 Intel Pentium Pro Intel Pentium II Intel Pentium III AMD Athlon AMD Duron Intel Pentium IV
Maker CPU Type Package Bus Speed (Mhz)
L1 | L2
Intel Pentium III750 AMD Athlon 600 AMD Duron 800 Intel Celeron 566 AMD K6-2 475 Intel Pentium II 450
7. Identify the fan types shown in Meyers Figure 2-3 on p.17
Meyers Lab 2.2 (Socket City)
2. Identify the different socket types in Figure 2-5 on Meyers P.20
3. Draw a line to match each CPU with its corresponding socket type
CPU Socket Type
Pentium P54C Socket 370
Pentium Pro Slot 1
Celeron (II) 600 Socket A
Athlon 1200 Socket 8
Pentium II Socket 7

Review/study for A+ in Depth chapter 4 quiz ,tomorrow
Begin reading A+ in Depth Chapter 5 on Motherboards, review the material on CPUs and
chipsets from page 175-202. Complete Meyers Labs 2.l - 2.2, if possible, using Internet
resources to look up information on CPU types, eternal data bus, address bus, and socket form factors.
