mov     [EventHandle], esi

Schedules a global event, which is an event that does not require a specific virtual machine to process it. Since any virtual machine can process the event, the system does not switch tasks before calling the function. This is an asynchronous service. The order in which events are processed is not defined. In other words, if two global events are scheduled, it is not defined which one is processed first.

Returns the event handle in ESI. The handle can be used in a subsequent call to the Cancel_Global_Event service to cancel the event.

GlobalEventCallback: Address of the callback function. For more information about the callback function, see GlobalEventCallback.
RefData: Reference data to be passed to the event callback function.

The callback function can carry out any actions and use any VMM services, subject to the remarks in GlobalEventCallback.
