Prepares the EMM hardware for a warm boot.
Notes:
* This function assumes that the next operation that the
operating system performs is a warm boot of the system.
* In general, this function will affect the current mapping
context, the alternate register set in use, and any other
expanded memory hardware dependencies which need to be
initialized at boot time.
* If an application decides to map memory below 640K, the
application must trap all possible conditions leading to a
warm boot and invoke this function before performing the
warm boot itself. |
