Int 2F Fn 8220  - Modres - Play Module                                     [s]

   AX = 8220h
   DX:CX -> MODPARM structure (see #2646)

Return: AX = status
       5722h succesful
       2000h parameters out of range
       other MODRES not installed

Format of MODPARM Structure:
Offset Size    Description (Table 2646)
 00h   WORD    signature 504Dh ("MP" = Modparm)
 02h   BYTE    output device (see #2648 at INT 2F/AX=8221h)
 03h   WORD    segment of start of main module (pattern) data
 05h 31    WORDs   segment of start of sample numbers 1-31
 43h   BYTE    pattern at which to start playing (00h to 7Fh)
 44h   BYTE    function
       00h play from pattern [offset 43h] until end of the song
       01h play indicated pattern [offset 43h] only
 45h   BYTE    Machine speed
       00h 10-12Mhz
       01h 12-25Mhz (default)
       02h 25Mhz+
       03h mix speed 10kHz (fast 8Mhz machines)
       04h mix speed 12kHz (10Mhz machines)
       05h mix speed 13kHz
       06h mix speed 8kHz (test for 8Mhz machines)
 46h   BYTE    allow >64k sample playing
       80h MOD has samples >64k in it
       else all samples in MOD are <64k

Notes: Main module data and all samples must start on segment boundaries.
   In version 2.00 (ONLY) this function carries on playing (works in
     the background)
