+--------!---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,

+--------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 - ???
+ 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 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"

+ 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
+ since the BOUND instruction also calls INT 05h, but returns control
+ to the BOUND instruction, a failed BOUND check will cause an infinite
+ loop of PrtScreens unless the INT 05 handler is aware of the problem
+ and checks whether the interrupt was invoked by a BOUND instruction

+--------H-09---------------------------------
+INT 09 C - IRQ1 - KEYBOARD DATA READY
+Desc: this interrupt is generated when data is received from the keyboard.
+ 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/

+ are only available on the 122-key keyboard and the Microsoft Natural

+ keyboard
+ in the default configuration, break codes are the make scan codes with

+ 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").
+ In addition to the keys listed in the table above, there are

+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 1990/09/14, but not
+ v8.01X dated 1992/02/28; mode 21h supported by 1992/02/28 version but not
+ 1990/09/14 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
