y*65536+x), for the current implementation is 1 (1.0)
* +36 = +0x24: 7*dword: reserved (0 in the current implementation)
* +64 = +0x40: 32*word: list of supported videomodes (each word
is number of a videomode, after list itself there are zeroes)
* +128 = +0x80: 32*(5*word): list of supported frequences of the
scannings for videomodes: for each videomode listed in the
previous field up to 5 supported frequences are given
(unused positions contain zeroes)
Remarks:
* Function initializes the driver (if it is not initialized yet)
and must be called first, before others (otherwise they will do
nothing and return -1).
* The current implementation supports only one frequency
of the scanning on videomode.
======================================================================
============ Function 21, subfunction 13, subsubfunction 2 ===========
================ Get information on current videomode. ===============
======================================================================
Parameters:
* eax = 21 - function number
* ebx = 13 - subfunction number
* ecx = 2 - number of the driver function
Returned value:
* eax = -1 - driver is not loaded or not initialized;
ebx,ecx are destroyed
* eax = [width]*65536 + [height]
* ebx = frequency of the vertical scanning (in Hz)
* ecx = number of current videomode
Remarks:
* Driver must be initialized by call to
driver function 1.
* If only screen sizes are required, it is more expedient to use
function 14 taking into account that it
returns sizes on 1 less.
======================================================================
=== Function 21, subfunction 13, subsubfunction 3 - set videomode. ===
======================================================================
Parameters:
* eax = 21 - function number
* ebx = 13 - subfunction number
* ecx = 3 - number of the driver function
* edx = [scanning frequency]*65536 + [videomode number]
Returned value:
* eax = -1 - driver is not loaded, not initialized or
an error has occured
* eax = 0 - success
* ebx, ecx destroyed
Remarks:
* Driver must be initialized by driver function 1.
* The videomode number and frequency must be in the table
returned by driver function 1.
======================================================================
============ Function 21, subfunction 13, subsubfunction 4 ===========
================== Return to the initial videomode. ==================
======================================================================
Returns the screen to the videomode set at system boot.
Parameters:
* eax = 21 - function number
* ebx = 13 - subfunction number
* ecx = 4 - number of the driver function
Returned value:
* eax = -1 - driver is not loaded or not initialized
* eax = 0 - success
* ebx, ecx destroyed
Remarks:
* Driver must be initialized by call to driver function 1.
======================================================================
============ Function 21, subfunction 13, subsubfunction 5 ===========
===== Increase/decrease the size of the visible area of monitor. =====
======================================================================
Parameters:
* eax = 21 - function number
* ebx = 13 - subfunction number
* ecx = 5 - number of the driver function
* edx = 0/1 - decrease/increase horizontal size on 1 position
* edx = 2/3 - is not supported in the current implementation;
is planned as decrease/increase vertical size on 1 position
Returned value:
* eax = -1 - driver is not loaded or not initialized
* eax = 0 - success
* ebx, ecx destroyed
Remarks:
* Driver must be initialized by call to driver function 1.
* Function influences only the physical size of the screen image;
the logical size (number of pixels) does not change.
======================================================================
================= Function 22 - set system date/time. ================

if the addition of ebx with the current value of time counter
makes 32-bit overflow.

======== Function 24, subfunction 1 - begin to play CD-audio. ========
======================================================================
Parameters:
* eax = 24 - function number
* ebx = 1 - subfunction number
* ecx = 0x00FRSSMM, where
* MM = starting minute
* SS = starting second
* FR = starting frame
Returned value:
* eax = 0 - success
* eax = 1 - CD base is not defined
Remarks:
* Previously CD base must be defined by the call to
subfunction 3 of function 21.
* One second includes 75 frames, one minute includes 60 seconds.
* The function is asynchronous (returns control, when play begins).
======================================================================
======= Function 24, subfunction 2 - get information on tracks. ======
======================================================================
Parameters:
* eax = 24 - function number
* ebx = 2 - subfunction number
* ecx = pointer to the buffer for the table
(maximum 8*64h+4 bytes=100 tracks)
Returned value:
* eax = 0 - success
* eax = 1 - CD base is not defined
Remarks:
* The format of the table with tracks information is the same as
for ATAPI-CD command 43h (READ TOC), usual table (subcommand 00h).
Function returns addresses in MSF.
* Previously CD base port must be set by call to
subfunction 3 of function 21.
* Function returns information only about no more than 100
first tracks. In most cases it is enough.
======================================================================
========== Function 24, subfunction 3 - stop play CD-audio. ==========
======================================================================
Parameters:
* eax = 24 - function number
* ebx = 1 - subfunction number
Returned value:
* eax = 0 - success
* eax = 1 - CD base is not defined
Remarks:
* Previously CD base port must be defined by call to
subfunction 3 of function 21.

======================================================================
Parameters:
* eax = 26 - function number
* ebx = 3 - subfunction number
Returned value:
* eax = CD base: 1=IDE0, 2=IDE1, 3=IDE2, 4=IDE3
Remarks:
* CD base is used by function 24.
* To set CD base use subfunction 3 of function 21.
