--------D-30---------------------------------
INT 30 - (NOT A VECTOR!) - DOS 1+ - FAR JMP instruction for CP/M-style calls
the CALL 5 entry point does a FAR jump to here
Note: under DOS 2+, the instruction at PSP:0005 points two bytes too low in
memory
SeeAlso: INT 21/AH=26h
--------D-31---------------------------------
INT 31 - overwritten by CP/M jump instruction in INT 30
--------v-31---------------------------------
INT 31 - VIRUS - "Vacsina" series - INSTALLATION CHECK (NOT A VECTOR!)
Note: if one of the Vacsina viruses is resident, the low byte of this
interrupt still contains the last byte of the INT 30 CP/M JMP
instruction, but the remaining three bytes are 7Fh 39h followed
by the Vacsina version number

Notes: up to three handlers can be defined by separate calls to this function,
each with a different combination of shift states in the call mask;
calling this function again with a call mask of 0000h undefines the

Values for subcode:
Subcode Function
DCh load 8086 stack with 8087 registers; overwrites the 10*N bytes at the
top of the stack prior to the INT 3E with the 8087 register contents
DEh load 8087 registers from top of 8086 stack; ST0 is furthest from top
of 8086 stack
E0h round TOS and R1 to single precision, compare, pop twice
returns AX=8087 status word, FLAGS=8087 condition bits
E2h round TOS and R1 to double precision, compare, pop twice
returns AX=8087 status word, FLAGS=8087 condition bits
Note: buggy in TPas5.5, because it sets the 8087 precision control
field to the undocumented value 01h; this results in actually
rounding to single precision
E4h compare TOS/R1 with two POP's
returns FLAGS=8087 condition bits
E6h compare TOS/R1 with POP
returns FLAGS=8087 condition bits
E8h FTST (check TOS value)
returns FLAGS=8087 condition bits
EAh FXAM (check TOS value)
returns AX=8087 status word

Program: MAGic (MAGnification In Color) is a TSR by Microsystems Software, Inc.
providing 2x2 text and graphics magnification on VGA, XGA, and SVGA
Note: INT 49 is the default, but may be overridden on the commandline. The
actual interrupt in use may be found by searching for the signature
"MAGic" or "xMAGic" (for the deluxe version) immediately preceding
the interrupt handler (this is also the installation check). MAGic
uses CodeRunneR, which places the signature "RT" at offset 0000h in
the interrupt handler's segment, followed by MAGic's TSR ID of
"VMAG".

INT 50 - IRQ0 relocated by DESQview
Notes: this is the default location for older versions; DESQview v2.26+
searches for unused ranges of interrupts and uses the lowest
available range in its list for relocating these IRQs and the next
lowest for relocating IRQ8-IRQ15
a range of eight interrupts starting at a multiple of 8 is considered
available if all vectors are identical and it has not been excluded
with an /XB:nn commandline switch
the list of ranges for v2.26 is 50h,58h,68h,78h,F8h (if < two of these
are available, F8h and then 50h are used anyway)
the list of ranges for v2.31+ is 68h,78h,88h-B8h,F8h (if < two of these
are available, F8h and then F0h are used anyway)

b) the signature 0Dh "INTRSPY vN.NN" immediately precedes the handler
If INTRSPY is installed, the DWORD immediately after the IRET stores
its entry point.

Notes: The handler for the interrupt will start with a 3-byte jump
instruction, followed by the ASCIZ string "PKT DRVR" (the

To find the interrupt being used by the driver, an application should
scan through interrupt vectors 60h to 80h (20h through FFh for
v1.10+ of the specification) until it finds one with the "PKT DRVR"
string.

DS:SI -> MDEBUG identification table
Program: MDEBUG is a shareware memory-resident debugging tool by Bernd
Schemmer, including a memory monitor, an interpreter, and a
disassembler
Notes: MDEBUG uses INT 60 by default, but may be directed to any of INT 60
through INT 67; the interrupt handler is preceded by the signature
"USERINT" and is not chained
if DS:SI points at a null byte, MDEBUG will prompt for a password if
passwords are active; enough stack space must be provided for an
INT 10h call (which MDEBUG uses while prompting for the password)
SeeAlso: AH=02h"MDEBUG"
