Ralf Brown Internet: ralf@telerama.lm.com UUCP: {uunet,harvard}!telerama.lm.com!ralf 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) CIS: >INTERNET:ralf@telerama.lm.com I reply to all e-mail submissions and inquiries, 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 (starting at harvard or ucbvax for UUCP, from the Internet for others). --------!------------------------------------ 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. 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 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, y - security, * - reserved (and not otherwise classified) --------C-00--------------------------------- INT 00 - 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 --------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 - 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 --------C-01--------------------------------- INT 01 - 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 --------H-02--------------------------------- INT 02 - 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 --------C-03--------------------------------- INT 03 - 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 SeeAlso: INT 01 --------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-030910----------------------------- INT 03 - Soft-ICE - BACK DOOR COMMANDS - DISPLAY STRING IN Soft-ICE WINDOW AX = 0910h SI = magic value 4647h ('FG') DI = magic value 4A4Dh ('JM') DS:DX -> ASCIZ string to display (max 100 bytes, 0Dh OK) Program: Soft-ICE is a debugger by Nu-Mega Technologies, Inc. --------G-030911----------------------------- INT 03 - Soft-ICE - BACK DOOR COMMANDS - EXECUTE Soft-ICE COMMAND AX = 0911h SI = magic value 4647h ('FG') DI = magic value 4A4Dh ('JM') DS:DX -> ASCIZ command string (max 100 bytes, 0Dh OK) --------G-030912----------------------------- INT 03 - Soft-ICE - BACK DOOR COMMANDS - GET BREAKPOINT INFORMATION AX = 0912h SI = magic value 4647h ('FG') DI = magic value 4A4Dh ('JM') Return: BH = entry number of last breakpoint set BL = type of last breakpoint set 00h BPM (breakpoint register types) 01h I/O 02h INTerrupt 03h BPX (INT 03h-style breakpoint) 04h reserved 05h range DH = entry number of last breakpoint to be triggered DL = type of last triggered breakpoint (see above) Program: Soft-ICE is a debugger by Nu-Mega Technologies, Inc.

SeeAlso: AX=0912h,AX=0913h --------C-04--------------------------------- INT 04 - CPU-generated - INTO DETECTED OVERFLOW Desc: the INTO instruction will generate this interrupt if OF (Overflow Flag) is set; otherwise, INTO is effectively a NOP Note: may be used for convenient overflow testing (to prevent errors from propagating) instead of JO or a JNO/JMP combination SeeAlso: INT 00 --------B-05--------------------------------- INT 05 - PRINT SCREEN Desc: dump the current text screen to the first printer Notes: normally invoked by the INT 09 handler when PrtSc key is pressed, but may be invoked directly by applications byte at 0050h:0000h contains status used by default handler 00h not active 01h PrtSc in progress FFh last PrtSc encountered error default handler is at F000h:FF54h in IBM PC and 100%-compatible BIOSes SeeAlso: INT 10/AH=12h/BL=20h --------C-05--------------------------------- INT 05 - CPU-generated (80186+) - BOUND RANGE EXCEEDED Desc: generated by BOUND instruction when the value to be tested is less than the indicated lower bound or greater than the indicated upper bound. Note: returning from this interrupt re-executes the failing BOUND instruction --------P-05454A----------------------------- INT 05 U - PSPS v2.01 - EJECT PAGE AX = 454Ah ('EJ') Program: PSPS is shareware PostScript PrintScreen utility by A.N.D.
