Function 68, subfunction 8 - read data from physical memory.
Parameters:
- eax = 68 - function number
- ebx = 8 - subfunction number
- ecx = physical address
- edx = pointer to buffer for data (in application)
- esi = size of data (in bytes)
Returned value:
- function does not return value
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 range of physical addresses should lie inside of previously
allocated by subfunction 5 block of physical memory.
- There is no check for correctness.
