Interrupt List Release 60 Last change 03jan99 Copyright (c) 1989,1990,1991,1992,1993,1994,1995,1996,1997,1998,1999 Ralf Brown --------!---FILELIST------------------------- Please redistribute the following files unmodified as a group, in a quartet of archives named INTER60A through INTER60D (preferably the original authenticated PKZIP archives): INTERRUP.1ST this file INTERRUP.A INT 00 through INT 10/BE \ INTERRUP.B INT 10/BF through INT 15/0F\ INTERRUP.C INT 15/10 through INT 15/E7 \ INTERRUP.D INT 15/E8 through INT 1A/B0 \ INTERRUP.E INT 1A/B1 through INT 1F \ total 2459 pages at INTERRUP.F INT 20 through INT 21/43 \ 60 lines per page, INTERRUP.G INT 21/44 through INT 21/5E \ 2615 with INTPRINT -p INTERRUP.H INT 21/5F through INT 21/E2 >(8653 entries) INTERRUP.I INT 21/E3 through INT 21/F1 / (4081 tables) INTERRUP.J INT 21/F2 through INT 25 / INTERRUP.K INT 26 through INT 2F/16 / INTERRUP.L INT 2F/17 through INT 2F/AC / INTERRUP.M INT 2F/AD through INT 30 / INTERRUP.N INT 31 through INT 5F / INTERRUP.O INT 60 through INT 61 / INTERRUP.P INT 62 through INT 6A / INTERRUP.Q INT 6B through INT 91 / INTERRUP.R INT 92 through INT FF / 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 BIBLIO.LST bibliography of information sources for the list CMOS.LST a description of the CMOS RAM data bytes FARCALL.LST APIs available through FAR CALLs GLOSSARY.LST a glossary of terms, abbreviations, and acronyms MEMORY.LST format of the BIOS data area and other memory regions MSR.LST a listing of Model-Specific Registers 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.COM combine the pieces of the list into a single file COMBINE.DOC documentation for COMBINE The following files should be distributed in an archive called INTER60E: 86BUGSnn.ZIP programs to test for CPU bugs COMBINE.ASM source code for COMBINE.COM INT.* invoke interrupts from commandline INTHLP??.ZIP Interrupt Helper viewer for the interrupt list INTLIST.E Epsilon extension for handling list INTPRINT.C source code for INTPRINT INTSUM??.ZIP interrupt list browser (Interrupt Summary) IVIEW.ZIP another interrupt list browser VIEWINTL.ZIP list viewer by Sly Golovanov The following should be distributed in an archive called INTER60F: INT2RTF.ZIP Slava Gostrenko's Windows Help converter INT2WHLP.ZIP convert list into Windows Help database HINTSRCH.ZIP WinHelp DLL for full-text searches of interrupt list WH_ED*.ZIP WinHelp-file editor Finally, the following should be distributed in an archive called INTER60G: IL2ME???.ZIP convert list into Multi-Edit help database INT2GUID.* convert list into TurboPower GUIDE or POPHELP database INT2HLP.ZIP convert list into QuickHelp database INT2QH.* program to convert list into QuickHelp database INT2TPH.ZIP convert to Turbo/Borland Pascal help file (.TPH) INTHELP.* convert list into TurboPower GUIDE database RB2NG???.ZIP convert list into Norton Guides database Concatenate INTERRUP.A, .B, ... with COMBINE.COM 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 ), a ready-made Norton Guides database (compiled by Michael Gallias and distributed as RBNGrr.*), and a ready-made WinHelp database (compiled by Ron Loewy <76350.333@compuserve.com> and occasionally distributed as INTWIN*.*). --------!---COPYRIGHT------------------------ NOTICE NOTICE NOTICE NOTICE (c) Copyright 1989,1990,1991,1992,1993,1994,1995,1996,1997,1998,1999 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 the interrupt list me rather than distributing a modified version of the list, so that all may benefit from your contribution. Corrections to programs contributed by others should be sent directly to their authors. Beitr„ge werden auch gerne in Deutsch angenommen! --------!---DISCLAIMER----------------------- 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. --------!---AVAILABILITY--------------------- If the list is three or more months old by the time you get it, there is probably a newer release out already (R56 is planned for mid-December, R57 for early March 1998). 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 two megs compressed it is much too large for that): On the Internet, by standard anonymous FTP from FTP.CS.CMU.EDU [128.2.206.173]. Change directly to directory /afs/cs.cmu.edu/user/ralf/pub and get the files inter??a.zip thru inter??g.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 the World-Wide Web, from http://www.pobox.com/~ralf/files.html On FIDOnet, from SoundingBoard BBS 1:129/26 1-412-621-4604 HST/V.32/V.34 as files INTERrrA.ZIP to INTERrrF.ZIP (rr stands for the release number), in file area #8. First-time callers may download. File Requests. Alternate Distribution Points (the list will typically be available here within 24 hours of release): Internet: on the SimTel.Net mirrors as files interRRa.zip to interRRg.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.Net mirrors include oak.oakland.edu [141.210.10.117], wuarchive.wustl.edu [128.252.135.4], ftp.uu.net [137.39.1.9], nic.funet.fi [128.214.6.100], src.doc.ic.ac.uk [146.169.3.7], and archie.au [139.130.4.6].

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 a mere 150K....] "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 information program). "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." --Ethan Dicks --------!---CONTACT_INFO--------------------- 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).

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. --------!---FLAGS---------------------------- The use of -> instead of = signifies that the indicated register or register pair contains a pointer to the specified item, rather than the item itself. Register pairs (such as AX:BX) indicate that the item is split across the registers, with the high-order half in the first register. One or more letters may follow the interrupt number; they have the following meanings: U - undocumented function, u - partially documented function, P - available only in protected mode, R - available only in real or V86 mode, C - callout or callback (usually hooked rather than called), O - obsolete (no longer present in current versions) --------!---CATEGORIES----------------------- The ninth column of the divider line preceding an entry usually contains a classification code (the entry has not been classified if that character is a dash). The codes currently in use are: A - applications, a - access software (screen readers, etc), B - BIOS, b - vendor-specific BIOS extensions, C - CPU-generated, c - caches/spoolers, D - DOS kernel, d - disk I/O enhancements, E - DOS extenders, e - electronic mail, F - FAX, f - file manipulation, G - debuggers/debugging tools, g - games, H - hardware, h - vendor-specific hardware, I - IBM workstation/terminal emulators, i - system info/monitoring, J - Japanese, j - joke programs, K - keyboard enhancers, k - file/disk compression, l - shells/command interpreters, M - mouse/pointing device, m - memory management, N - network, n - non-traditional input devices, O - other operating systems, P - printer enhancements, p - power management, Q - DESQview/TopView and Quarterdeck programs, R - remote control/file access, r - runtime support, S - serial I/O, s - sound/speech, T - DOS-based task switchers/multitaskers, t - TSR libraries U - resident utilities, u - emulators, V - video, v - virus/antivirus, W - MS Windows, X - expansion bus BIOSes, x - non-volatile config storage y - security, * - reserved (and not otherwise classified) --------C-00--------------------------------- INT 00 C - CPU-generated - DIVIDE ERROR Desc: generated if the divisor of a DIV or IDIV instruction is zero or the quotient overflows the result register; DX and AX will be unchanged. Notes: on an 8086/8088, the return address points to the following instruction on an 80286+, the return address points to the divide instruction an 8086/8088 will generate this interrupt if the result of a division is 80h (byte) or 8000h (word) SeeAlso: INT 04,OPCODE "AAD" --------G-00--------------------------------- INT 00 - Zenith - ROM DEBUGGER Desc: invokes the ROM Debugger when at the BIOS level; equivalent to pressing Ctrl-Alt-Ins on booting. Note: since DOS revectors INT 00, it is necessary to restore this vector to its original ROM BIOS value in order to invoke the debugger once DOS loads SeeAlso: INT 03"Columbia" --------C-01--------------------------------- INT 01 C - CPU-generated - SINGLE STEP Desc: generated after each instruction if TF (trap flag) is set; TF is cleared on invoking the single-step interrupt handler Notes: interrupts are prioritized such that external interrupts are invoked after the INT 01 pushes CS:IP/FLAGS and clears TF, but before the first instruction of the handler executes used by debuggers for single-instruction execution tracing, such as MS-DOS DEBUG's T command SeeAlso: INT 03"CPU" --------C-01--------------------------------- INT 01 C - CPU-generated (80386+) - DEBUGGING EXCEPTIONS Desc: generated by the CPU on various occurrences which may be of interest to a debugger program Note: events which may trigger the interrupt: Instruction address breakpoint fault - will return to execute inst Data address breakpoint trap - will return to following instruction General detect fault, debug registers in use Task-switch breakpoint trap undocumented 386/486 opcode F1h - will return to following instruc SeeAlso: INT 03"CPU" --------H-02--------------------------------- INT 02 C - external hardware - NON-MASKABLE INTERRUPT Desc: generated by the CPU when the input to the NMI pin is asserted Notes: return address points to start of interrupted instruction on 80286+ on the 80286+, further NMIs are disabled until the next IRET instruction, but one additional NMI is remembered by the hardware and will be serviced after the IRET instruction reenables NMIs maskable interrupts may interrupt the NMI handler if interrupts are enabled although the Intel documentation states that this interrupt is typically used for power-failure procedures, it has many other uses on IBM-compatible machines: Memory parity error: all except Jr, CONV, and some machines without memory parity Breakout switch on hardware debuggers Coprocessor interrupt: all except Jr and CONV Keyboard interrupt: Jr, CONV I/O channel check: CONV, PS50+ Disk-controller power-on request: CONV System suspend: CONV Real-time clock: CONV System watch-dog timer, time-out interrupt: PS50+ DMA timer time-out interrupt: PS50+ Low battery: HP 95LX Module pulled: HP 95LX --------m-02----SI0714----------------------- INT 02 U - STB RAPIDMAP.SYS - ???

An alternate keyboard configuration can be enabled on AT and later systems with enhanced keyboards, in which break codes are the same as make codes, but prefixed with an F0h scan code prefix code E0h indicates that the following make/break code is for a "gray" duplicate to a key which existed on the original PC keyboard; prefix code E1h indicates that the following make code has no corresponding break code (currently only the Pause key generates no break code) the Microsoft Natural Keyboard sends make codes 5Bh, 5Ch, and 5Dh (all with an E0h prefix) for the Left Windows, Right Windows, and Menu keys on the bottom row the European "Cherry G81-3000 SAx/04" keyboard contains contacts for four additional keys, which can be made available by a user modification; the three new keys located directly below the cursor pad's Delete, End, and PgDn keys send make codes 66h-68h (F19-F21); the fourth new key, named , sends make code 73h the SysReq key is often labeled SysRq the "Accord" ergonomic keyboard with optional touchpad (no other identification visible on keyboard or in owner's booklet) has an additional key above the Grey- key marked with a left-pointing triangle and labeled "Fn" in the owner's booklet which returns scan codes E0h 68h on make and E0h E8h on break the "Preh Commander AT" keyboard with additional F11-F22 keys treats F11-F20 as Shift-F1..Shift-F10 and F21/F22 as Ctrl-F1/Ctrl-F2; the Eagle PC-2 keyboard with F11-F24 keys treated those additional keys in the same way [Note1] the "Cherry G80-0777" keyboard has additional F11-F15 keys which generate make codes 55h-59h; some other extended keyboards generate codes 55h and 56h for F11 and F12, which cannot be managed by standard DOS keyboard drivers [Note2] the Schneider/Amstrad PC1512 PC keyboards contain extra keys, a mouse, and a digital joystick, which are handled like extra keys. The joystick's motion scancodes are converted into standard arrow keys by the BIOS, and the joystick and mouse button scan codes are converted to FFFFh codes in the BIOS keyboard buffer (see CMOS 15h"AMSTRAD").

B800 DEC VAXmate AT&T mode Notes: [1] interlaced only [2] for ATI EGA Wonder, mode 08h is only valid if SMS.COM is loaded resident. SMS maps mode 08h to mode 27h if the byte at location 0040:0063 is 0B4h, otherwise to mode 23h, thus selecting the appropriate (monochrome or color) 132x25 character mode. for ATI VGA Wonder, mode 08h is the same, and only valid if VCONFIG loaded resident [3] early XGA boards support 132-column text but do not have this BIOS mode [4] DESQview intercepts calls to change into these two modes (21h is page 0, 22h is page 1) even if there is no Hercules graphics board installed [5] ATI BIOS v4-1.00 has a text-scrolling bug in this mode [6] for AT&T VDC overlay modes, BL contains the DEB mode, which may be 06h, 40h, or 44h [7] BIOS text support is broken in this undocumented mode; scrolling moves only about 1/3 of the screen (and does even that portion incorrectly), while screen clears only clear about 3/4. [8] The Oak OTI-037/067/077 modes are present in the Oak VGA BIOS, which OEMs may choose to use only partially or not at all; thus, not all Oak boards support all "Oak" modes listed here [9] this card uses the full 128K A000h-BFFFh range for the video buffer, precluding the use of a monochrome adapter in the same system [10] mode 17h supported by Tseng ET4000 BIOS 8.01X dated 09/14/90, but not v8.01X dated 02/28/92; mode 21h supported by 02/28/92 version but not 09/14/90 version [11] HERKULES simulates a 90x45 text mode in Hercules graphics mode; the installation check for HERKULES.COM is the signature "Herkules" two bytes beyond the INT 10 handler [12] The Realtek RTVGA BIOS v3.C10 crashes when attempting to switch into modes 21h or 27h; this version of the BIOS also sets the BIOS data area incorrectly for extended text modes, resulting in scrolling after only 24 lines (the VMODE.EXE utility does set the data area correctly) [13] The Tandy 1000SL/TL BIOS does not actually support this mode [14] HERCULES.COM is a graphics-mode BIOS extension for Hercules-compatible graphics cards by Soft Warehouse, Inc. Its installation check is to test whether the word preceding the INT 10 handler is 4137h. [15] The Hercules-graphics video modes for HERCBIOS (shareware by Dave Tutelman) may be changed by a command-line switch; the 90x43 character-cell mode's number is always one higher than the 90x29 mode (whose default is mode 08h) [16] Stealth64 Video 2001-series BIOS v1.03 reports 76 lines for mode 7Ch, resulting in incorrect scrolling for TTY output (scrolling occurs only after the end of the 76th line, which is not displayed) [17] For 43-line text on EGA or 43/50-line text on VGA, you must load an 8x8 font using AX=1102h after switching to mode 3; VGA may also require using INT 10/AH=12h/BL=30h SeeAlso: #00011,#00083,#00191 Index: video modes Index: installation check;HERKULES|installation check;HERCULES.COM --------V-100070----------------------------- INT 10 - VIDEO - Everex Micro Enhancer EGA/Viewpoint VGA - EXTENDED MODE SET AX = 0070h BL = mode (see #00011) Desc: specify a proprietary display mode on the Everex Micro Enhancer or Viewpoint video adapters SeeAlso: AH=00h,AX=6F05h,AX=7000h/BX=0004h,AH=FFh"GO32" (Table 00011) Values for Everex video mode: text/ text pixel pixel colors disply scrn monitor adapter grph resol box resolution pages addr 00h = G . . 640x480 16 . . multisync EGA,VGA 01h = G . . 752x410 16 . . multisync EGA,VGA 02h = G . . 800x600 16 . . multisync EGA,VGA 03h = T 80x34 . . . . . multisync EGA,VGA 04h = T 80x60 . . . . . multisync EGA,VGA 05h = T 94x29 . . . . . multisync EGA only 06h = T 94x51 . . . . . multisync EGA only 07h = T 100x43 8x14 . 16 . . .
