Mike Meyers' Passport to A+ Certification (1st Edition), by Mike Meyers and Tracey Rosenblath
Errata
p. 6. The default I/O address for LPT1 is 378. The default for LPT2 is 278.
p. 17, Answer to question 9 should be A, not B. The text should read as follows:
The USB ports on the back of your PC use the flatter Type A connector. You use the square Type B connector to plug into some USB devices.
p. 50, Table 3-1, EISA cards under 8-bit ISA should be no. Also, EISA cards under 16-bit ISA should be no.
p. 60, answer #8 should read (change in bold): "ATX power supplies connect to ATX motherboards..."
p. 78, third paragraph, second sentence. The Celeron 300A has 128 KB of level 2 cache, not 128 MB.
p. 79, second paragraph. The discussion of variations of Pentium III CPUs got garbled somehow. Starting from the sentence, "Other variations exist as well," here's how the paragraph should read.
Intel released numerous models of Pentium III CPUs that incorporated new features, such as a 133 MHz system bus, Advanced Transfer Cache (ATC), and improved cache buffering. The bewildering variety available at some clock speeds led to some confusion on the part of techs. The 600 MHz model, for example, came out in at least six different flavors. There was the plain 600, that ran on a 100 MHz bus and had a slow, 512 KB L2 cache; the 600B, that ran on a 133 MHz bus and had 256 KB L2 ATC cache that ran at the speed of the CPU; the 600E, that had the improved cache, but ran on a 100 MHz bus clock; and the 600EB that had all the goodies! Plus, Intel released the 600 in two different form factors, PGA and SEC. It was enough to drive a tech crazy! Not content with mere speed and performance increases, Intel also equipped the Pentium III with an enhanced version of MMX, called SSE (Streaming SIMD Extensions) to handle the many multimedia chores required by the truly important applications—games!
p. 81, second paragraph. The Athlon processors came with either 256 KB or 512 KB of L2 cache, not 256 MB.
p. 92, third line from the bottom. You can find 72-pin SIMMs in 1-64 MB sticks.
p. 110, second sentence under the Partitioning heading should read as follows (changes in bold):
Both enable you to create at least two partitions on a drive...
Make the same change on Objective 7.04 Checkpoint on page 112.
p. 119, first paragraph, third sentence. This should read: “The SCSI standard sets the priority of the SCSI IDs at 7 for the highest and 0 for the lowest.”
p. 135, question 3. Answer D should read 25-pin parallel rather than 28-pin parallel.
p. 140, last sentence of the Travel Advisory should read, "You can destroy RAM or slot if you install RAM when the motherboard is hot."
p. 161, first sentence of second paragraph should read "...to default to IRQ7 or IRQ5."
p. 164, Exam Tip should read, "Know your DMA channels!"
p. 193, last paragraph, first sentence. This should read: “Installing a network interface card (NIC) into any version …”
p. 201, question 9 should read (changes in bold): "You can add new devices in all the following ways, except"
p. 205, the caption for Figure 12-1 is incorrect. It should read: "Inside a dot matrix printer."
p. 233-234, question 12. The question is a bit ambiguous as written and does not adequately reflect the potential pitfalls of working inside a laser printer. The power supply (not one of the choices) is probably the single most dangerous of all the parts. Of the four options listed, any of them can hurt you. The question will change in subsequent printings.
p. 256, answer 2, needs to change slightly. It should read as follows:
D. It's highly unlikely that the entire Internet would go down! The other three options are fairly common problems that would lead to no dial tone. An extension phone could be in use, the cable or the phone line might not be connected.
p. 275, under “Objective 14.05: Duplex Explained.” The last sentence should read: “Parallel connections use half duplex.”
p. 304, answer 6 should be D rather than B. The explanation is correct.
p. 326, Figure 16-3: The memory locations on the right of the figure should all be five digits in length. Each location should have an additional “F” on the end of the address.
p. 358, third sentence under the heading “Install Problems” should read: “Usually, something else fails in the system during the install process, resulting in something called an install failure.”
p. 366, the correct answer to question 2 should be B and D: “The Windows Startup Disk needs the CONFIG.SYS and AUTOEXEC.BAT files to access a CD-ROM.”
p. 475, fourth paragraph. The discussion says that “Microsoft wanted Windows 2000 to support many different types of partitions, old and new—NTFS, FAT16, FAT32, HPFS …” HPFS should not be included in this list. Microsoft dropped support for HPFS beginning with Windows NT 4.0, so Windows 2000 does not support HPFS.
p. 467. The first sentence under the heading “TCP/IP” should begin with “Transmission Control Protocol.”
