Ralf Brown Internet: ralf@pobox.com (currently forwards to ralf@telerama.lm.com) FIDO: Ralf Brown 1:129/26.1 or post a message to me in the DR_DEBUG echo (I probably won't see it unless you address it to me) I reply to all e-mail submissions, but some of my replies bounce because of bad return paths. If you don't get a response from me within a reasonable period of time, send it again with a better return path (many mailers are improperly configured and do not produce a valid From: address). --------!---Note----------------------------- See INTERRUP.1ST for the key to system abbreviations and a list of the trademarks mentioned here. --------!---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. --------!---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 - ???

SeeAlso: INT 67/AX=6100h"STB",PORT 00E1h"STB" --------C-03--------------------------------- INT 03 C - CPU-generated - BREAKPOINT Desc: generated by the one-byte breakpoint instruction (opcode CCh) Notes: used by debuggers to implement breakpoints, such as MS-DOS DEBUG's G command also used by Turbo Pascal versions 1,2,3 when {$U+} specified return address points to byte following the breakpoint instruction called by Novell DOS 7 EMM386 after displaying an exception error message (GPF, illegal opcodes, etc.) and before waiting for user input called by QEMM-386 if the user presses 'I' (undocumented) when prompted after an exception error message SeeAlso: INT 01"CPU" --------G-03--------------------------------- INT 03 - Columbia PCs (desktop,VP portables) - ROM DEBUGGER Desc: invokes the ROM Debugger if INT 03 has not been revectored; equivalent to pressing Esc on booting. SeeAlso: INT 00"Zenith",INT 03"Realia" --------G-03--------------------------------- INT 03 - Realia COBOL - DEBUGGER SUPPORT Note: Realia COBOL checks for a signature eight bytes prior to the interrupt handler when it starts up BUG: if the offset of the INT 03 vector is less than 8, the compiler and all executables generated by it will crash the system SeeAlso: INT 03"Columbia" --------G-03--------------------------------- INT 03 U - Watcom WVIDEO, Watcom WD - OUTPUT DEBUGGING MESSAGE STACK: DWORD selector DWORD offset of ASCIZ message to display Notes: the INT 03h instruction which invokes the debugger must be followed by a JMP SHORT and the signature string "WVIDEO" to check whether this interface is available, define a public byte variable named ___WD_Present, which the debugger will set to 01h before running the program SeeAlso: AX=0910h --------U-03--------------------------------- INT 03 - DTown Utilities - POP UP Program: DTown Software Development's DTown Utilities contains various tools which are useful to programmers, such as a memory viewer and disassembler Note: DTU pops up on INT 03 (if not hooked by a debugger) to allow the user to inspect memory or code when the machine crashes; various memory managers will invoke INT 03 when displaying a CPU exception error message (either automatically or when the user presses a particular key) SeeAlso: INT 2D/AL=20h"DTown" --------G-030000----------------------------- INT 03 - Soft-ICE - BACK DOOR COMMANDS - GET Soft-ICE VERSION AX = 0000h SI = magic value 4647h ('FG') DI = magic value 4A4Dh ('JM') Return: SI = BCD version (0280h = v2.80) SeeAlso: INT 03/AX=0910h --------G-0301------------------------------- INT 03 - Soft-ICE - BACK DOOR COMMANDS - ???

Technologies SeeAlso: AX=454Ah,AX=4E57h,INT 17/AH=62h --------C-06--------------------------------- INT 06 C - CPU-generated (80286+) - INVALID OPCODE Desc: this interrupt is generated when the CPU attempts to execute an invalid opcode (most protected-mode instructions are considered invalid in real mode) or a BOUND, LDS, LES, or LIDT instruction which specifies a register rather than a memory address Notes: return address points to beginning of invalid instruction with proper programming, this interrupt may be used to emulate instructions which do not exist; many 386 BIOSes emulate the 80286 undocumented LOADALL instruction which was removed from the 80386+ generated by the 80386+ when the LOCK prefix is used with instructions other than BTS, BTR, BTC, XCHG, XADD (486), CMPXCHG (486), INC, DEC, NOT, NEG, ADD, ADC, SUB, SBB, AND, OR, or XOR, or any instruction not accessing memory. SeeAlso: INT 0C"CPU",INT 0D"CPU" --------b-06--------------------------------- INT 06 C - HP 95LX - SLEEP/WAKEUP Desc: this interrupt is called just before going into light or deep (shutdown) sleep and just after returning from light or deep sleep SeeAlso: INT 0B"HP 95LX",INT 15/AX=4DD4h,INT 15/AH=4Eh --------V-06--------------------------------- INT 06 U - no-name clone - GRAPHICS CHARACTER TABLE (NOT A VECTOR!)

This is normally a scan code (from either a keypress *or* a key release), but may also be an ACK or NAK of a command on AT-class keyboards. Notes: this IRQ may be masked by setting bit 1 on I/O port 21h if the BIOS supports an enhanced (101/102-key) keyboard, it calls INT 15/AH=4Fh after reading the scan code (see #00006) from the keyboard and before further processing; all further processing uses the scan code returned from INT 15/AH=4Fh the default interrupt handler is at F000h:E987h in 100%-compatible BIOSes the interrupt handler performs the following actions for certain special keystrokes: Ctrl-Break clear keyboard buffer, place word 0000h in buffer, invoke INT 1B, and set flag at 0040h:0071h SysReq invoke INT 15/AH=85h (SysReq is often labeled SysRq) Ctrl-Numlock place system in a tight wait loop until next INT 09 Ctrl-Alt-Del jump to BIOS startup code (either F000h:FFF0h or the destination of the jump at that address) Shift-PrtSc invoke INT 05 Ctrl-Alt-Plus (HP Vectra) enable keyclick Ctrl-Alt-Plus (many clones) set clock speed to high Ctrl-Alt-Minus (HP Vectra) reduce keyclick volume Ctrl-Alt-Minus (many clones) set clock speed to low Ctrl-Alt-SysReq (HP Vectra) generate hard reset Ctrl-Alt-S (many clones) run BIOS setup program Ctrl-Alt-Esc (many clones) run BIOS setup program Ctrl-Alt-Ins (many clones) run BIOS setup program Ctrl-Alt-LeftShift-GrayMinus (some clones) turn off system cache Ctrl-Alt-LeftShift-GrayPlus (some clones) turn on system cache DR DOS hooks this interrupt to control the cursor shape (underscore/ half block) for overwrite/insert mode DR Multiuser DOS hooks this interrupt for cursor shape control and to control whether Ctrl-Alt-Del reboots the current session or the entire system SeeAlso: INT 05"PRINT SCREEN",INT 0B"HP 95LX",INT 15/AH=4Fh,INT 15/AH=85h SeeAlso: INT 16/AH=00h,INT 16/AH=10h,INT 1B,INT 2F/AX=A901h,INT 4A/AH=00h"TI" SeeAlso: INT 51"DESQview",INT 59"DoubleDOS",INT 79"GO32" (Table 00006) Values for keyboard make/break (scan) code: 01h Esc 31h N 02h 1 ! 32h M 03h 2 @ 33h , < 63h F16 04h 3 # 34h . > 64h F17 05h 4 $ 35h / ? 65h F18 06h 5 % 36h Right Shift 66h F19 07h 6 ^ 37h Grey* 67h F20 08h 7 & 38h Alt 68h F21 (Fn) [*] 09h 8 * 39h SpaceBar 69h F22 0Ah 9 ( 3Ah CapsLock 6Ah F23 0Bh 0 ) 3Bh F1 6Bh F24 0Ch - _ 3Ch F2 6Ch -- 0Dh = + 3Dh F3 6Dh EraseEOF 0Eh Backspace 3Eh F4 0Fh Tab 3Fh F5 6Fh Copy/Play 10h Q 40h F6 11h W 41h F7 12h E 42h F8 72h CrSel 13h R 43h F9 73h <delta> [*] 14h T 44h F10 74h ExSel 15h Y 45h NumLock 75h -- 16h U 46h ScrollLock 76h Clear 17h I 47h Home 77h [Note2] Joyst But1 18h O 48h UpArrow 78h [Note2] Joyst But2 19h P 49h PgUp 79h [Note2] Joyst Right 1Ah [ { 4Ah Grey- 7Ah [Note2] Joyst Left 1Bh ] } 4Bh LeftArrow 7Bh [Note2] Joyst Up 1Ch Enter 4Ch Keypad 5 7Ch [Note2] Joyst Down 1Dh Ctrl 4Dh RightArrow 7Dh [Note2] right mouse 1Eh A 4Eh Grey+ 7Eh [Note2] left mouse 1Fh S 4Fh End 20h D 50h DownArrow 21h F 51h PgDn 22h G 52h Ins 23h H 53h Del 24h J 54h SysReq ---non-key codes--- 25h K 55h [Note1] F11 00h kbd buffer full 26h L 56h left \| (102-key) 27h ; : 57h F11 AAh self-test complete 28h ' " 58h F12 E0h prefix code 29h ` ~ 59h [Note1] F15 E1h prefix code 2Ah Left Shift 5Ah PA1 EEh ECHO 2Bh \ | 5Bh F13 (LWin) F0h prefix code (key break) 2Ch Z 5Ch F14 (RWin) FAh ACK 2Dh X 5Dh F15 (Menu) FCh diag failure (MF-kbd) 2Eh C FDh diag failure (AT-kbd) 2Fh V FEh RESEND 30h B FFh kbd error/buffer full Notes: scan codes 56h-E1h are only available on the extended (101/102-key) keyboard and Host Connected (122-key) keyboard; scan codes 5Bh-5Dh are only available on the 122-key keyboard and the Microsoft Natural Keyboard; scan codes 5Eh-76h are only available on the 122-key keyboard in the default configuration, break codes are the make scan codes with the high bit set; make codes 60h,61h,70h, etc. are not available because the corresponding break codes conflict with prefix codes (code 2Ah is available because the self-test result code AAh is only sent on keyboard initialization). 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 <delta>, 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 . . .
