Third IDE controller:

If the hard disk on IDEx is absent, appropriate byte is zero,
otherwise it shows number of the recognized partitions, which
can be not presented (if the drive is not formatted or if
the file system is not supported). Current version of the kernel
supports only FAT16, FAT32 and NTFS for hard disks.
* +6: 4 db: reserved
supports only FAT12/16/32, NTFS, ext2/3/4 and XFS for hard disks.

============== Function 21, subfunction 3 - set CD base. =============
======================================================================
Parameters:
* eax = 21 - function number
* ebx = 3 - subfunction number
* ecx = CD base: 1=IDE0, 2=IDE1, 3=IDE2, 4=IDE3
Returned value:
* eax = 0

======================================================================
========== Function 21, subfunction 5 - set system language. =========
======================================================================
Parameters:
1252,120 → 1263,6
* To get current status use subfunction 12 of function 26.
 
======================================================================
============ Function 21, subfunction 13, subsubfunction 1 ===========
======== Initialize + get information on the driver vmode.mdr. =======
======================================================================
Parameters:
* eax = 21 - function number
* ebx = 13 - subfunction number
* ecx = 1 - number of the driver function
* edx = pointer to 512-bytes buffer
Returned value:
* if driver is not loaded
(never happens in the current implementation):
* eax = -1
* ebx, ecx destroyed
* if driver is loaded:
* eax = 'MDAZ' (in fasm style, that is 'M' - low byte, 'Z' - high)
- signature
* ebx = current frequency of the scanning (in Hz)
* ecx destroyed
* buffer pointed to by edx is filled
Format of the buffer:
* +0: 32*byte: driver name, "Trans VideoDriver"
(without quotes, supplemented by spaces)
* +32 = +0x20: dword: driver version (version x.y is encoded as
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.
 
======================================================================

returned by driver function 1.
