The installation check is to a) determine that the handler is an IRET instruction 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. INTRSPY is a script-driven debugger included with the book _Undocumented_DOS_. Call INTRSPY entry point with: AH = function 00h ??? 01h set current directory (for use in reporting) ES:DI -> counted string containing directory name (max 79 char) 02h set name of script file ES:DI -> counted string containing file name (max 79 chars) 03h set script arguments ES:DI -> counted string containing arguments (max 79 chars) 04h get directory set with function 01h ES:DI -> 80-byte buffer for directory name 05h get name of script file ES:DI -> 80-byte buffer for script filename 06h get script arguments ES:DI -> 80-byte buffer for script arguments 07h get ???

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. AH values of 80h to FFh have been reserved for user-defined additions. ----------6000------------------------------- INT 60 - SYS_PROF.EXE - PROFILER STATUS AH = 00h Return: AX = 0000h profiling is off otherwise profiling is on Note: SYS_PROF.EXE is the TSR portion of a profiler from Micro Cornucopia #47 SeeAlso: AH=01h"SYS_PROF",02h"SYS_PROF" ----------6000------------------------------- INT 60 - MDEBUG - GET STATUS AH = 00h DS:SI -> password or a null byte Return: AX = return code FFFEh password is invalid FFFDh display mode is invalid else successful ES = value of the monitor register SE DI = value of the monitor register OF CH = monitor color CL = debugger color BH = monitor start line BL = debugger start line AH = makecode of the hotkey AL = ASCII code of the hotkey DL = status of special keys (only SHIFT, ALT, CTRL) for the hotkey (coded as for the keyboard flag at 0040h:0017h) DH = basic process number for the communication with drivers process number for the display driver, DH+1 = process number for the command driver(s) DS:SI -> MDEBUG identification table Notes: MDEBUG is a shareware memory-resident debugger by Bernd Schemmer 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 SeeAlso: AH=02h"MDEBUG" Format of MDEBUG identification table: Offset Size Description -2 WORD entry offset 00h WORD CS of MDEBUG 02h DWORD old INT 08h vector 06h DWORD old INT 09h vector 0Ah DWORD address INT 16h routine used by MDEBUG 0Eh BYTE length of version string 0Fh N BYTEs version string ----------6001------------------------------- INT 60 - MDEBUG - GET ADDRESS OF THE HELP REGISTERS AH = 01h DS:SI -> password or a null byte Return: AX = return code FFFEh password is invalid FFFDh display mode is invalid else successful ES:DI point to the help registers of MDEBUG ES:DI-02h -> R0 ES:DI -> R1 ES:DI+02h -> R2 ES:DI+04h -> R3 ...
