--------!---FLAGS----------------------------
The use of -> instead of = signifies that the indicated register or re
gister
pair contains a pointer to the specified item, rather than the item it
self.
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 fol
lowing
meanings: U - undocumented function, u - partially documented functio
n,
P - available only in protected mode, R - available only in real or V8
6 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 contai
ns a
classification code (the entry has not been classified if that charact
er 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 ins
truction
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 vect
or to
its original ROM BIOS value in order to invoke the debugger once DO
S
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 in
voked
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 inte
rest
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 80
286+
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-----------------------

SI = 0714h
ES:DI -> ???
Return: ???
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 DEBU
G'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 prompt
ed
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; equi
valent
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 int
errupt
handler when it starts up
BUG: if the offset of the INT 03 vector is less than 8, the compiler a
nd
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 foll
owed 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)
