For CD-drives due to hardware limitations only subfunctions
0,1,5 and 7 are available, other subfunctions return error
with code 2.
At the first call subfunctions 0,1,5,7 to devices ATAPI (CD and DVD) the locking
of handle mechanism of a tray is made. It is connected to algorithm of caching
given obtained from a drive. Deblocking is made by call subfunction 10
to the appropriate device.

Parameters:
* eax = 70 - function number
* ebx = pointer to the information structure
Format of the information structure:

* +21 = +0x15: dd pointer to ASCIIZ-string with folder name
Returned value:
* Nothing comes back.
Remarks:
* The function is supported only for ATAPI devices (CD and DVD).
* At extract of a tray is made deblocking of handle mechanism of a tray.
* At extract of a tray the code makes clearing the cache of the appropriate device.
* The path is standard for 70 functions. For serviceability it is possible to be limited to paths:
