, 
, 
, respectively.
p. 64, second paragraph. "Now let's count to 1000: 0, 1, 10, 11, 100, 101, 110, 11, 1000." should read "Now let's count to 1000: 0, 1, 10, 11, 100, 101, 110, 111, 1000."

p. 109, first paragraph. The sentence that begins "You can even see this cache in Figure 2.13 . . . ." should be deleted. It referred to a picture of a Pentium Pro that had the processor and cache chips exposed; deleted in favor of typical Pentium Pro CPU photo.
p. 123, second paragraph. ". . . and a +5-volt DC wire (Figure 3.12)" should read ". . . and a +5-volt CD wire (Figure 3.13)."
p. 142, first paragraph. The sentence that begins "The following are some current . . . ." should be deleted.

p. 213, third paragraph. ". . . chedk the motherboard book" should read ". . . check the motherboard book."
p. 228. The I/O Address range 0210-0217 and its "Reserved" usage should appear on the chart above the I/O Address range 0278-027F. Lines 17 and 18, in other words, are reversed on the chart.
p. 225, sixth paragraph, first line. ". . . its own hex shorthand: 00 (0), 0001 (1) . . ." should read ". . . its own hex shorthand: 0000 (0), 0001 (1) . . ."

p. 245, third paragraph. "They are distinct in that they names such as Intel . . . ." should read "They are distinct in that they have names such as Intel . . . ."
p. 276, first paragraph. The 160K floppy disk was single-sided, rather than dual-sided. Thanks goes to reader Harlan C. for having a better memory than mine!
p. 276. The last sentence, which begins "There is no way to tell . . . " should read as follows: "It's tough to tell the difference between any of these 3.5-inch disks with casual observation." As reader Thomas P. points out, however, to a trained observer the differences are a bit more obvious: a 720K disk has only the write-protect hole, whereas the 1.44MB disk has two holes.
p. 299, first paragraph. The sentence that reads "If you're observant, you have probably noticed that master and 1 drive are the same setting; this is quite common" should be changed. The new sentence should read as follows: "Often, master and 1 drive are the same setting on the hard drive, although some manufacturers require separate settings."

p. 329, third paragraph. "If you are using Windows 95, you can also . . . " should read "If you are using Windows 95 OSR2 or beyond, you can also . . ."
p. 333. The chart "TAXREC.XLS fragmented" (Figure 8.43) has errors in lines 3-5. Here is how the chart should appear:
Cluster Status 3ABB 3ABC 3ABC 3ABE 3ABD FFF7 3ABE 3AC4 3ABF 3AC0 3AC0 3AC1 3AC1 FFFF 3AC2 3AC3 3AC3 FFFF 3AC4 3AC5 3AC5 3AC6 3AC6 FFFF 3AC7 0000
p. 342, fourth paragraph. ". . . although some didn't it." should read ". . . although some didn't need it."
p. 361, Table 9.2. Six instances of MB/S should read MB/s.
p. 362, Table 9.3. A couple of typos in the table. Under SSA, MB/S should read MB/s. Under IEEE1394, MB/S actually should be Mb/s, for megabits per second, rather than megabytes per second. To keep the numbering uniform, the correct top speed is 50 MB/s, rather than 400MB/s. Also 72 meers should read 72 meters.
p. 365, first paragraph. The reference to Figure 9.26 is in the wrong place. It should follow the third sentence rather than the second. It refers to the SCSI "P" cable.
p. 374. Append the following sentence to the first paragraph under RAID: "SCSI devices use some of the Random Array of Inexpensive Disks (RAID) standards for disk arrays, most notably RAID 0, 1, 3, and 5."
p. 375, last sentence should read "A ZIP drive is 100MB or 250MB in size . . . ." to reflect the new technology.
p. 388. Reader George G. pointed out that our comment about the death of Kermit was not only premature, but also inaccurate. The book states that Kermit "was the first synchronous protocol used for uploading and downloading from a mainframe. It is considered very slow, and is virtually unused today." The new versions of Kermit seem to be up on the times and, according to George and the Kermit website, can be as fast or faster than any other transfer protocol. Want some solid evidence? Go to the Kermit website and see for yourself: http://www.columbia.edu/kermit/kermit.html
p. 392, last paragraph. The Microcom company (rather than Micron) created the Microcom Networking Protocol, also known as MNP.
p. 394, Table 10.3. The explanation of ATH, ATH0, should read "Makes the modem hang up."
p. 432, first line. ". . . you'd need 22 bits (four bits per pixel)." should read ". . . you'd need 2 bits."
p. 466, eighth bullet point. "Printing a completely black page . . . " should read "Printing a completely blank page . . . "
p. 509, near end of page. Change the command "C:\>PROMPT $E[1;34;40m$P$G$E[0;37;40m" to "C:\>PROMPT $e[1;34;40m$P$G$e[0;37;40m"
p. 510, second line. Change the command "C:\>PROMPT $E[0;31;47$p$g$E[0;37;40m" to "C:\>PROMPT $e[0;31;47m$p$g$e[0;37;40m"
p. 515, second paragraph. ". . . you learned that a lost cluster chain is a series to clusters . . ." should read ". . . you learned that a lost cluster chain is a series of clusters . . ."

p. 528, fourth paragraph. ". . . to counter unknwn polymorphs. . . " should read ". . . to counter unknown polymorphs . . ."
p. 547, fourth paragraph. "...the command WIN /D:C." should read "...the command WIN /D:F."
p. 550. The first sentence under 32-Bit File Access should read as follows (changes in bold): If you have Windows for Workgroups or Windows 3.11 and have IFSHLP.SYS loaded in CONFIG.SYS (which loads by default in these versions), you can enable 32-bit file access to make Windows even faster.
p. 592, first paragraph. "You can change these settings by accessing the Device Manager/Performance Tab/File System button . . ." should read "You can change these settings by accessing the System Properties/Performance Tab/File System button . . . ."
p. 613, first paragraph. ". . . you don't say 10110110011000101101 or 10110110011000101101." should read ". . . you don't say things like 10110110011000101101."
p. 629, first paragraph. ". . . in order to use them, ships must populating the addresses above FFFFF" should read ". . . in order to use them, chips must populate the addresses above FFFFF."
p. 653. The device driver SETVER.EXE causes problems with some systems when loading high. Other systems have no problems with it. We suggest avoiding problematic drivers when doing memory management, but if you need an extra few K of Conventional memory, try loading SETVER.EXE high. It might work for you! According to the DOS 6 manual, as pointed out by reader Dave T., SETVER.EXE should be able to load high.
p. 658, third paragraph. ". . . you can save over 4K of valuable UMB space by reducing the value to 6." should read " . . . you can save over 4K of valuable UMB space by reducing the value to 4."

p. 689, first paragraph; three errors: "low voltage ac outlets" should read "low voltage AC outlets"; "clean dc" should read "clean DC"; and "pure dc" should read "pure DC"
p. 697, first paragraph (under bullet points). ". . . from the president to all notice PC users" should read ". . . from the president to all novice PC users."
p. 761, TCP/IP section. TCP/IP stands for Transmission Control Protocol/Internet Protocol, rather than Terminal Control Protocol/Internet Protocol.
p. 790, first paragraph. "Classically, CD-ROM drives are installed as secondary slaves or primary master in systems with one hard drive" should read "Classically, CD-ROM drives are installed as primary slave or secondary master in systems . . . ."
