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).

--------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
--------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
--------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
--------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
--------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
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-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

--------C-04---------------------------------
INT 04 C - 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

	  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.
	  Technologies
Note:	sends a ^D to the current printer

	AX = 4E57h ('NW')
	ES:SI -> 11-byte buffer containing new settings
Return: buffer filled

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!)
Desc:	points at graphics data for characters 00h-7Fh of the current font
SeeAlso: INT 43"EGA",INT 44"VIDEO"
--------C-07---------------------------------
INT 07 C - CPU-generated (80286+) - PROCESSOR EXTENSION NOT AVAILABLE
Desc:	this interrupt is automatically called if a coprocessor instruction is
	  encountered when no coprocessor is installed
Note:	can be used to emulate a numeric coprocessor in software
SeeAlso: INT 09"MATH UNIT PROTECTION"
--------H-08---------------------------------
INT 08 C - IRQ0 - SYSTEM TIMER
Desc:	generated 18.2 times per second by channel 0 of the 8254 system timer,
	  this interrupt is used to keep the time-of-day clock updated
Notes:	programs which need to be invoked regularly should use INT 1C unless
	  they need to reprogram the timer while still keeping the time-of-day
	  clock running at the proper rate
	default handler is at F000h:FEA5h in IBM PC and 100%-compatible BIOSes
	may be masked by setting bit 0 on I/O port 21h
SeeAlso: INT 1C,INT 4A,INT 50"DESQview",INT 58"DoubleDOS",INT 70,INT 78"GO32"
SeeAlso: INT D8"Screen Thief"
--------C-08---------------------------------
INT 08 C - CPU-generated (80286+) - DOUBLE EXCEPTION DETECTED
Desc:	called when multiple exceptions occur on one instruction, or an
	  exception occurs in an exception handler
Notes:	called in protected mode if an interrupt above the defined limit of
	  the interrupt vector table occurs
	return address points at beginning of instruction with errors or the
	  beginning of the instruction which was about to execute when the
	  external interrupt caused the exception
	if an exception occurs in the double fault handler, the CPU goes into
	  SHUTDOWN mode (which circuitry in the PC/AT converts to a reset);
	  this "triple fault" is a faster way of returning to real mode on
	  many 80286 machines than the standard keyboard controller reset
--------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 #0005) 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
	DRDOS 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

INT 09 C - CPU-generated (80286,80386) - PROCESSOR EXTENSION PROTECTION ERROR
Desc:	called if the coprocessor attempts to access memory outside a segment
	  boundary; it may occur at an arbitrary time after the coprocessor
	  instruction was issued
Notes:	until the condition is cleared or the coprocessor is reset, the only
	  coprocessor instruction which may be used is FNINIT; WAIT or other
	  coprocessor instructions will cause a deadlock because the
	  coprocessor is still busy waiting for data
	for the 486+, a coprocessor protection error generates an INT 0D

--------*-09---------------------------------
INT 09 P - internal hardware - RESERVED BY Intel (80486)
Note:	this exception has been moved to INT 0D
SeeAlso: INT 09"MATH",INT 0D
--------H-0A---------------------------------
INT 0A C - IRQ2 - LPT2 (PC), VERTICAL RETRACE INTERRUPT (EGA,VGA)
Notes:	the TOPS and PCnet adapters use this interrupt request line by default
	DOS 3.2 revectors IRQ2 to a stack-switching routine
	on ATs and above, the physical data line for IRQ2 is labeled IRQ9 and
	  connects to the slave 8259.  The BIOS redirects the interrupt for
	  IRQ9 back here.
	under DESQview, only the INT 15h vector and BASIC segment address (the
	  word at 0000h:0510h) may be assumed to be valid for the handler's
	  process
	many VGA boards do not implement the vertical retrace interrupt,
	  including the IBM VGA Adapter where the traces are either cut or
	  removed

--------H-0A---------------------------------
INT 0A C - IRQ2 - Tandy 1000-series HARD DISK
Notes:	this interrupt may be masked by setting bit 2 on I/O port 21h
	the Tandy 1000, 1000A, and 1000HD use IRQ2 for the hard disk; the
	  1000EX, HX, RLX, RLX-HD, RLX-B, RLX-HD-B use IRQ5 instead; the
	  1000RL, RL-HD, SL, SL/2, TL, TL/2, and TL/3 are jumper-selectable
	  for either IRQ2 or IRQ5 (default IRQ5); the 1000SX and TX are
	  DIP-switch selectable for IRQ2 or IRQ5 (default IRQ2); the RSX and
	  RSX-HD use IRQ14.  Tandy systems which use IRQ2 for the hard disk
	  interrupt use IRQ5 for vertical retrace.

--------H-0A---------------------------------
INT 0A - IRQ2 - ROLAND MPU MIDI INTERFACE
Note:	newer Roland cards and MIDI interfaces by other manufacturers use
	  a jumper-selectable IRQ, but software and hardware generally defaults
	  to IRQ2

INT 0A CP - CPU-generated (80286+) - INVALID TASK STATE SEGMENT
Desc:	automatically called during a task switch if the new TSS specified by
	  the task gate is invalid for any of the following reasons:
		TSS limit is less than 43 (80286) or 103 (80386/80486)
		LDT selector invalid or segment not present
		null SS selector, or SS selector outside LDT/GDT limit
		stack segment is read-only
		stack segment DPL differs from new CPL, or RPL <> CPL
		CS selector is outside LDT/GDT limit or not code
		non-conforming code segment's DPL differs from CPL
		conforming code segment's DPL > CPL
		DS/ES selectors outside LDT/GDT limit or not readable segments
Note:	the handler must use a task gate in order to have a valid TSS under
	  which to execute; it must also reset the busy bit in the new TSS

INT 0C C - CPU-generated (80286+) - STACK FAULT
Desc:	this interrupt is generated in protected mode on a stack overflow or
	  underflow, or if an inter-level transition or task switch references
	  a stack segment marked "not present"; it is generated in real mode
	  on accessing a word operand at SS:FFFFh
Note:	the 80286 will shut down in real mode if SP=1 before a push.  On the
	  PC AT and compatibles, external circuitry generates a reset on
	  shutdown.

Notes:	under DESQview, only the INT 15h vector and BASIC segment address (the
	  word at 0000h:0510h) may be assumed to be valid for the handler's
	  process
	the Tandy 1000, 1000A, and 1000HD use IRQ2 for the hard disk; the
	  1000EX, HX, RLX, RLX-HD, RLX-B, RLX-HD-B use IRQ5 instead; the
	  1000RL, RL-HD, SL, SL/2, TL, TL/2, and TL/3 are jumper-selectable
	  for either IRQ2 or IRQ5 (default IRQ5); the 1000SX and TX are
	  DIP-switch selectable for IRQ2 or IRQ5 (default IRQ2); the RSX and
	  RSX-HD use IRQ14.  Tandy systems which use IRQ2 for the hard disk
	  interrupt use IRQ5 for vertical retrace.

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.

Return:	CF set on error

Program: 2M is a TSR developed by Ciriaco Garcia de Celis to support
	  non standard diskettes with 820-902/1476-1558K (5.25 DD/HD)
	  and 984-1066/1804-1886K/3608-3772K (3.5 DD/HD/ED)
Notes:	it is not necessary to call AH=17h/AH=18h first (will be ignored)
	the diskette format must always begin on cylinder 0 head 0
	the boot sector can be obtained from an already-formatted 2M diskette
	  (by calling AH=02h with head number 00h in 2M v1.x and with head
	  number 80h for 2M v2+)
	the installation check for 2M must search for a "CiriSOFT:2M:1.3" or
	  "CiriSOFT:2MX:3.0" or similar (recomended ":2M:" or ":2MX:"
	  substrings) in CiriSOFT TSR interface
	since 2M v2.0, the BOOT sector is emulated using the first physical
	  sector of FAT2; the second-sixth physical sectors of FAT2 in HD or ED
	  diskettes store the SuperBOOT code. To skip the FAT2 emulation (using
	  FAT1) of 2M, in order to read the SuperBOOT code, head number must be
	  80h-81h instead 0-1 (bit 7 active) in standard read/write functions.
	  This lets diskcopy programs format 2M target diskettes copying
	  SuperBOOT code. If the target diskette is already 2MF formatted
	  (containing boot code) this trick it is not necessary.
	when using STV technology (offset 65 of boot sector equal to 1) it is
	  necessary to write the full track before formatting (except track 0
	  side 0) to complete the format and skip future CRC errors on read; in
	  track 0 side 1 the head used must be 81h instead 1. Diskcopy programs
	  may do a format-write-verify sequential phases to improve performance

INT 19 - SYSTEM - BOOTSTRAP LOADER
Desc:	This interrupt reboots the system without clearing memory or restoring
	  interrupt vectors.  Because interrupt vectors are preserved, this
	  interrupt usually causes a system hang if any TSRs have hooked
	  vectors from 00h through 1Ch, particularly INT 08.
Notes:	Usually, the BIOS will try to read sector 1, head 0, track 0 from drive
	  A: to 0000h:7C00h.  If this fails, and a hard disk is installed, the
	  BIOS will read sector 1, head 0, track 0 of the first hard disk.
	  This sector should contain a master bootstrap loader and a partition
	  table (see #0502).  After loading the master boot sector at
	  0000h:7C00h, the master bootstrap loader is given control.  It will
	  scan the partition table for an active partition, and will then load
	  the operating system's bootstrap loader (contained in the first
	  sector of the active partition) and give it control.
	true IBM PCs and most clones issue an INT 18 if neither floppy nor hard
	  disk have a valid boot sector
	to accomplish a warm boot equivalent to Ctrl-Alt-Del, store 1234h in
	  0040h:0072h and jump to FFFFh:0000h.	For a cold boot equivalent to
	  a reset, store 0000h at 0040h:0072h before jumping.
	VDISK.SYS hooks this interrupt to allow applications to find out how
	  much extended memory has been used by VDISKs (see #0501).  DOS 3.3+
	  PRINT hooks INT 19 but does not set up a correct VDISK header block
	  at the beginning of its INT 19 handler segment, thus causing some
	  programs to overwrite extended memory which is already in use.
	the default handler is at F000h:E6F2h for 100% compatible BIOSes
	MS-DOS 3.2+ hangs on booting (even from floppy) if the hard disk
	  contains extended partitions which point at each other in a loop,
	  since it will never find the end of the linked list of extended
	  partitions
	under Windows Real and Enhanced modes, calling INT 19 will hang the
	  system in the same was as under bare DOS; under Windows Standard
	  mode, INT 19 will successfully perform a cold reboot as it appears
	  to have been redirected to a MOV AL,0FEh/OUT 64h,AL sequence

	IBM and many clone BIOSes set the flag for AL rather than incrementing
	  it, leading to loss of a day if two consecutive midnights pass
	  without a request for the time (e.g. if the system is on but idle)
	since the midnight flag is cleared, if an application calls this
	  function after midnight before DOS does, DOS will not receive the
	  midnight flag and will fail to advance the date
