at the end of the Details section, there is extraneous space between

Page 6-27, Interrupt 13h Function 1Dh
the "Registers at call" section is not correctly indented. It should
be indented as
AH = 1Dh
AL = subfunction
01h get status record
DL = drive
02h set cache status
ES:BX -> status record
DL = drive
Page 6-28, Interrupt 13h Function 22h

Page 6-38, Interrupt 21h Function 44h Subfunction 10h

other registers unknown
Page 8-19, Interrupt 21h Function 33h Subfunctions 00h and 01h

Table 8-49a. Format of current directory structure for DR-DOS 5.0-6.0
Offset Size Description
00h 67 BYTEs ASCIZ pathname of actual root directory for this
logical drive
43h WORD drive attributes
1000h SUBSTed drive
3000h??? JOINed drive
4000h physical drive
5000h ASSIGNed drive
7000h JOINed drive
45h BYTE physical drive number (0=A:) if this logical drive
is valid
46h BYTE ??? apparently flags for JOIN and ASSIGN
47h WORD cluster number of start of parent directory
(0000h = root)
49h WORD entry number of current directory in parent
directory
4Bh WORD cluster number of start of current directory
4Dh 2 BYTEs ??? apparently always 0001h
4Fh WORD cluster number of SUBST/JOIN "root" directory
0000h if physical root directory
Page 8-55, Tables 8-52 and 8-53
at offset 00h, "if last least-recently" should read "if last; least-
recently"
Page 8-79, Interrupt 21h Function 5Eh Subfunction 04h
under Purpose, "operation" should be "operate"
Page 8-83, Interrupt 21h Function 60h
Backslashes really messed things up here. The end of "Return
Registers" should read
buffer filled with qualified name of form
D:\PATH\NAME.EXT or \\MACHINE\PATH\NAME.EXT
At the end of the first paragraph of the Details section, the single
backslash in quotes should be two backslashes.
Page 8-108, Interrupt 2Fh Function 12h Subfunction 11h
There is an extraneous vertical bar after "Return Registers:"
Page 8-134, Interrupt 2Fh Function 10h Subfunction 80h
under "Details", delete "they may also be turned off with the
undocumented /NC commandline switch".
Page 8-135, Interrupt 2Fh Function 19h Subfunction 04h
The last two lines of this entry should be under Return Registers,
indented as
ES:DI -> ...
WORD ...
N BYTEs ...
Page 10-1, Interrupt 2Fh Function 43h Subfunction 10h
A number of items are incorrectly indented in the description of the
calls to the driver entry point. For function 01h, the calling
registers should be indented as
01h Request High Memory ...
DX = memory in bytes ...
FFFFh if application program
For functions 0Ah, 0Bh, 0Dh (page 10-2), 0Fh, and 11h (page 10-3), the
return value BL should be indented on tab stop beyond "0000h failure",
as it is for function 06h.
Page 10-7, Interrupt 67h Function 4Ch
There is an extraneous blank line under "Return Registers".
Page 10-17, Virtual Control Program Interface
"to have multiplex" should read "to have multiple"
Page 10-20, Interrupt 67h Function DEh Subfunction 09h
Details: should read "Values for DR4 and DR5 are ignored."
Page 10-20, Interrupt 67h Function DEh Subfunction 0Ah
In the Purpose section, "interrupt" is misspelled as "interrutp".
Page 11-1, Interrupt 2Fh Function FBh Subfunction 42h
under Return Registers, there should be no indenting. All lines should
start in the same column as "Return Registers".
On the Conflicts: line, "None known" was erroneously boldfaced.
Page 11-2, Interrupt 2Fh Function 16h Subfunction 87h
The lines "Call Mode Switch entry point with:" and "Mode Switch routine
returns with:" should have been boldfaced.
Page 11-4, Interrupt 31h Function 00h Subfunction 02h
on the Purpose: line, "descritor" should be "descriptor"
Page 11-18, Table 11-11
"12 Bytes" should be "12 BYTEs"
Page 11-23, Interrupt 31h Function 06h Subfunction 02h and Subfunction 03h
The Purpose: sections of these two entries were accidentally exchanged.
Subfunction 02h permits the memory to be paged out while Subfunction
03h prevents memory from being paged out.
Page 11-30, Interrupt 31h Function 0Dh Subfunction 02h
The "Registers at call" section should be indented as
DX = flags
bit 0: return immediately rather than suspending
if serialization unavailable
1: ...
Page 12-1, Interrupt 4Bh Function 81h Subfunction 02h
The heading was not boldfaced. The end of the Return Registers section
should be indented as follows:
CF set on error
AL = error code (see Table 12-1)
Page 13-1, Microsoft Mouse
"Microsoft Mouse The Microsoft mouse driver" should read just "The
Microsoft mouse driver"
Page 13-11, Interrupt 33h Function 0024h
under Return Registers, "on errorotherwise" should read "on error; otherwise"
Page 13-16, Interrupt 33h Function 0042h
The Return Registers section should be indented as
AX = FFFFh ...
BX = buffer size....
= 0000h ...
= 0042h ...
Page 14-1, Interrupt 16h Function 6Fh Subfunction 00h
The lines under "Registers at call" and "Return Registers" were
erroneously boldfaced. After the book appeared, I was informed that
this call is actually an HP Vectra installation check, and thus should
be in chapter 4 rather than chapter 14.
Page 14-1, Interrupt 2Fh Function 16h Subfunction 00h
The Available on: and Restrictions: sections were erroneously
boldfaced.
Page 14-4, Interrupt 2Fh Function 16h Subfunction 81h
the last two sentences of the Details section should be a single
sentence; replace "2.x. Get" with "2.x; get"
Page 14-9, Interrupt 2Fh Function 17h Subfunction 0Ah
tables 14-6 and 14-7 were omitted during the publication process.
Under "Registers at call" it should read "(see Table 14-6)", while the
"Return Registers" section should read "(see Table 14-7)". The two
tables are reproduced here in their entirety.

Page 15-1, Interrupt 10h Function FFh

Page 15-10, Interrupt 15h Function 12h Subfunction 00h

There is an extraneous blank line under both "Registers at call" and
"Return Registers"
Page 15-35, Interrupt 15h Function 12h Subfunction 0Ch

I/O". There is also an extraneous blank line under "Registers at call"
Page 15-37, Interrupt 15h Function 12h Subfunction 0Eh
there should have been a line break between "keyboard: discard input"
and "timer: cancel current interval"
Page 15-40, Interrupt 15h Function 12h Subfunction 11h
The "STACK: DWORD ..." line should not have been indented
Page 15-40, Interrupt 15h Function 12h Subfunction 12h
The "STACK: DWORD ..." line should not have been indented
Page 15-44, Interrupt 15h Function DEh Subfunction 00h
New information has become available indicating that the return value
is the offset of the program most recently selected from the "Switch
Windows" menu, rather than the calling program.
Page 15-44, Table 15-7
at offset 00h, add "(FFh if end of file)"
change the last two lines to read
BYTE program type
WORD apperently always 0000h
Page 15-54, Interrupt 21h Function 2Bh
The last two lines of the "Registers at call" section should not have
been indented.
Page 15-55, Interrupt 2Fh Function DEh Subfunction 01h
There is an extraneous blank line prior to the Details section.
Page 16-3, Interrupt 14h Function 23h
under "Return Registers", the line describing bit 6 of AH was indented
much more than it should have been.
Page 17-1, Interrupt 11h Function FFh Subfunction FEh
under "Return Registers", the return values for calls 01h and 02h
("DX:AX -> unknown" and "n/a") should not be indented
Page 17-8, Interrupt 15h Function 54h Subfunction 00h and Subfunction 01h

Page 28-7, Interrupt 21h Function 2Bh Subfunction 44h
I have been informed that the Return Registers should read
AX = 4F4Bh ('OK') if large host loaded
= 6F6Bh ('ok') if small host loaded
CX:DX -> API entry point

Page 36-41, Interrupt 2Fh Function D1h Subfunction 03h and Subfunc 04h
in both entries, under Return Registers, for AH = 04h, "redefinded"
should of course be "redefined". This error was in the original
interrupt list....
Page 36-50, Table 36-17
the second line of the description for value 08h was not sufficiently
indented.
Page 36-59, Table 36-19
The first word of the description for value 0Ch should be "fetch" not
"etch". The table also has several misaligned entries on the following
page.
In addition to the above, throughout the book there are numerous items
which should line up vertically but do not.
