p. 18, the pretest answer for Chapter 1, question 5 should read: "USB allows up to 127 devices per chain, while FireWire allows 63."
p. 47, the first paragraph under the header BNC Connectors needs clarification and should read as follows. Changes are in bold.
BNC connectors, also known as coaxial or coax connectors, are beginning to fade from common PC use, but many PCs still have coax connectors hanging out the back (see Figure 1-43). The coax cable used with PCs looks similar to the one that runs into the back of your TV.p. 98, first paragraph, second line. 232 should be 232.
p. 117, Table 2-7. The packages listed for the first two processors, the Pentium P5 60 and 66 MHz should be Socket 4, rather than Socket 5. The packages for the P54C 75, 90, 100, and 120 MHz CPUs should be Sockets 5, 7.
p. 149, Table 2-20. The Pentium 4 chart is hopelessly out of date as Intel continues to crank out newer, faster, better processors. Here's what it should be as of 1 April 2002 (sources Intel, SiS, VIA):

pp. 153-4, questions 9 and 10 have formatting issues. Here's how they should read:
9. Jane, the hardware technician for a non-profit corporation, has ten systems that she needs to upgrade with new microprocessors. Each system currently has an ATX motherboard with a Slot 1 Intel Pentium II 266 MHz installed. The motherboards can operate at voltages between 2.0-2.9 volts. In order to keep the upgrade costs low, her boss has told her to use the existing motherboards if possible.
Primary objective: Upgrade the systems with faster CPUs.
Optional objectives: Use existing motherboards and avoid adding any hardware aside from the CPU.Proposed solution: Jane places an order for ten PPGA Celeron 533 MHz processors and ten slockets for PGA to Slot 1 conversion.
The proposed solution:
A. Meets only the primary objective.
B. Meets the primary objective and one of the optional objectives.
C. Meets the primary objective and both of the optional objectives.
D. Meets only the optional objectives.10. A donor gives five SEC-style Athlon 800 MHz processors to the non-profit corporation for which Jane works as a technician. She has several systems with ATX motherboards and Slot 1 Intel Pentium III 800 MHz CPUs installed. Her boss wants her to upgrade five systems with the new processors, but to keep the upgrade costs low if possible by using the existing motherboards.
Primary objective: Upgrade the systems with faster CPUs.
Optional objective: Use existing motherboards.Proposed solution: Remove the Pentium III CPUs on five systems and replace them with the new Athlon CPUs.
The proposed solution:
A. Meets only the primary objective.
B. Meets only the optional objective.
C. Meets the primary and optional objectives
D. Meets neither objective.
p. 241, first full paragraph should read in the past, not present tense, as follows:
The LPX and NLX form factors met the demands of the slimline market by providing a central riser slot to enable the insertion of a special riser card. Expansion cards then fit into the riser card horizontally. Combining built-in connections with a riser card enabled manufacturers to produce PCs shorter than 4 inches.
p. 267, last paragraph, fourth sentence should read (changes in bold): "So any ISA card could in theory use IRQs 2 through 7."
p. 309, Table 5-10. The RAM type for the i845 chipset should be PC133, rather than PC33.
p. 567, second paragraph under FAT32, first sentence, should read as follows (added words in bold): "Let me begin by saying that FAT 32 is optional on all versions of Windows that support it."
p. 584, item #3 near the bottom of the page. The line to load in CONFIG.SYS should read as follows, with the slight change in bold:
DEVICE=A:\OAKCDROM.SYS /D:CDROM
p. 585, figure 10-46, should display the CONFIG.SYS line as follows:
DEVICE=A:\OAKCDROM.SYS /D:CDROM
p. 680-681, Improvements in NTFS. NTFS 5.0 offers four, not five improvements over NTFS 4.0. Compression should not be on the list as you could easily compress files and folders in NTFS 4.0.
For practical purposes, change the last sentence on page 680 to the following:
NTFS 5.0 adds four improvements: encryption, drive naming…
On page 681, simply delete the header and paragraph on Compression.
p. 817, "Beyond A+" section. The correct URL for the Paralan Corporation is www.paralan.com, not .org as written.
p. 991, item 2 under USB, second sentence should read (change in bold) "...with the exception of Windows 95A and Windows NT."
p. 1073, last sentence above the Exam Tip ("Active Directory is not required...") should be deleted. Windows 2000 domain-based networks require Active Directory.
LearnKey video CD-ROM 3, Session 3, Ports, CMOS Settings. The graphic showing LPT ports 1 and 2 and their associated IRQs and I/O addresses shows the I/O addresses reversed. The correct facts are: LPT1 has I/O address 378h, and LPT2 has I/O address 278h. Here is what the graphic should look like:
