Interrupt List Release 43 Last change 11/6/94
Please redistribute the following files unmodified as a group, in a trio of
archives named INTER43A through INTER43C (preferably the original authenticated

INTERRUP.PRI a brief primer on interrupts
INTPRINT.COM a simple formatter that also generates a list summary
INTPRINT.DOC instructions for INTPRINT
OVERVIEW.LST brief listing of major uses of each interrupt
86BUGS.LST a listing of CPU bugs and undocumented features
CMOS.LST a description of the CMOS RAM data bytes
GLOSSARY.LST a glossary of terms, abbreviations, and acronyms
MEMORY.LST format of the BIOS data area
OPCODES.LST a listing of recent and undocumented CPU instructions
PORTS.LST a listing of I/O ports
CATEGORY.KEY descriptions of divider-line category letters
COMBINE.BAT combine the pieces of the list into a single file
The following files should be distributed in an archive called INTER43D:
INT.* invoke interrupts from commandline
INT2GUID.* convert list into TurboPower GUIDE or POPHELP database
INT2HLP.BAT Perl script to convert list into QuickHelp database
INT2QH.* convert list into QuickHelp database
INT2WHLP.* convert list into Windows Help database
INTERVUE.EXE indexed interrupt list browser
INTHELP.* convert list into TurboPower GUIDE database
INTLIST.E Epsilon extension for handling list
INTLIST.ICO Windows icon for INTERVUE
INTPRINT.C source code for INTPRINT
RB2NG.* convert list into Norton Guides database
Concatenate INTERRUP.A, .B, .C, .D, .E, .F, .G, .H, .I, .J, .K, and .L with
COMBINE.BAT to create an interrupt list file identical to my master copy.
Use INTPRINT to generate a one-line-per-call summary file and/or a file
containing only data structure formats. See INTPRINT.DOC for details.
Note: in addition to the archives mentioned above, you may also find other
archives named INTERrrx containing additional files generated from the
original distribution for your convenience. These other archives are
maintained by other people, so please do not ask me any questions about them
(all I'll do is refer you to the creator). The additional distributions
I am currently aware of contain a ready-made Quick Help database (compiled
by Brad Willcott
database (compiled by Michael Gallias
as RBNGrr.*), and a ready-made WinHelp database (compiled by Ron Loewy
<[email protected]> and occasionally distributed as INTWIN*.*).
NOTICE NOTICE NOTICE NOTICE
This compilation is (c) Copyright 1989, 1990, 1991, 1992, 1993 Ralf Brown
Permission is granted to use and redistribute the files comprising the
interrupt listing in any way (including conversion to another format),
provided that my name and addresses and the names of all contributers
are preserved, as well as the information on how to obtain new releases.
The above requirement to give credit is waived for excerpts totaling
less than 2000 lines (although common courtesy indicates that you
should give some form of acknowledgment).
Some of the archives in the distribution contains programs contributed
by others; these programs are included as a service to users of the
interrupt list and the authors retain the rights to their programs.
Please send corrections/additions to me rather than distributing a
modified version of the list, so that all may benefit from your
DISCLAIMER: THIS MATERIAL IS PROVIDED "AS IS". I verify the information
contained in this list to the best of my ability, but I cannot be held
responsible for any problems caused by use or misuse of the information,
especially for those functions not officially documented. If it is marked
"internal" or undocumented, you should check it carefully to make sure it
works the same way in your version of the software (and please let me know
whether or not it works the same way). Information marked with "???" is
known to be incomplete or guesswork.
If the list is three or more months old by the time you get it, there
is probably a newer release out already (R44 is planned for early January 1995,
R45 for early March). Each release supersedes all previous versions, so
there is no need to keep old versions.
The newest release of this list is available in these places (please do not
ask me to email it, at over one meg compressed it is much too large for that):
On the Internet, by standard anonymous FTP from FTP.CS.CMU.EDU [184.108.40.206].
Change directly to directory /afs/cs.cmu.edu/user/ralf/pub and get the
files inter??a.zip thru inter??d.zip. You MUST change directory first
and in a single command because of the way CMU's anonymous FTP works.
Don't forget to set mode "binary" or "type L 8"!
If connected to AFS, you can simply perform standard Unix/VMS/whatever
directory listing and file copies from the above directory.
On FIDOnet, from SoundingBoard BBS 1:129/26 1-412-621-4604 9600/14.4k HST/V32
as files INTERrrA.ZIP to INTERrrD.ZIP (rr stands for the release
number), in file area #8. First-time callers may download.
Alternate Distribution Points (the list will typically be available here
within 24 hours of release):
Internet: on the SimTel Software Repository mirrors as files interRRa.zip to
interRRd.ZIP in directory /pub/msdos/info, where RR stands for the
release number. Note that you must use a binary transfer mode
("tenex" or "type L 8" for most people) to successfully FTP the
files. The SimTel mirrors include oak.oakland.edu [220.127.116.11],
wuarchive.wustl.edu [18.104.22.168], ftp.uu.net [22.214.171.124],
nic.funet.fi [126.96.36.199], src.doc.ic.ac.uk [188.8.131.52], and

concurrently with a new release of the list. Since comp.binaries.ibm.pc is

What they're saying about this list:
"A cornucopia of descriptions of interrupt and function calls on the
IBM PC. A great thing to have on your hard disk if you don't have
a Ray Duncan or Peter Norton book handy."
_Turbo_Technix_, July/August 1988, p. 157.
[and that was about the 1/30/88 version, which was only one-twentienth the size
of the current version....]
"An enormous listing of DOS and BIOS interrupt calls, many undocumented
and program-specific. Quite simply, some of Snooper's reports wouldn't
be there without it. Very useful in that it reports bugs and
incompatibilities books rarely mention. And it's free!"
John P. Vias, SNOOPER.DOC v1.07 (Snooper is a shareware system
"Ralf Brown maintains an astounding file which is chock-full of
detailed, absolutely-indispensable information for DOS programmers on
Hardware, BIOS, DOS, and other interrupts. .... You should not be
without this file, which is widely-known as "Ralf Brown's Interrupt
List". Ask about it. You will find it."
Robert Curtis Davis, TBONES07.DOC.
"It's the finest mess 'o Purina Geek Chow that I've seen in a coon's age."
If you know of any information not in the list, or which is stated incorrectly,
please let me know! This list would be a pale shadow of its current self if it
weren't for everybody's input.
Software developers are encouraged to check the list before assigning
interrupts, and to provide me with a list of interrupt calls used (to help
prevent future interrupt conflicts).
