Resets Memory Manager. Access Key returned at next invocation.
Lets the OS allow other programs or device drivers to use the OS
specific functions. This capability is provided only for an OS
which manages regions of mappable conventional memory and cannot
permit programs to use any of the functions which affect that
memory, but must be able to use these functions itself.
Note: This function is for use by operating systems only. The
operating system can disable this function at any time. |
