Remarks:
|

* Normal applications must not use this function, it is intended
|

for the case, when for some device it is required to place
|
||||
data to the known physical address. (In effect, this function
|

was developed for AC97WAV.)
|

* The number of blocks of physical memory is limited (by constant
|

24, and this constant includes some blocks for kernel).
|
||||
* To free a memory allocated by such way use
|
||||
subfunction 6, to copy data there and back
|
||||
use subfunctions 7 and 8.
|
||||
* The function call initializes heap, from which one can in future
|
||||
allocate and free memory blocks with subfunctions 12 and 13.
|
||||
Heap size is equal to total amount of free application memory.
|
||||
* The second function call from the same process results in

returning the size of the existing heap.

* The memory must be previously allocated by subfunction 5.

* Before this call one must initialize process heap by call to
