include vmm.inc mov edx, Port ; I/O port number VMMcall Disable_Global_Trapping |
The Disable_Global_Trapping service disables I/O port trapping for the specified I/O port. This applies to every virtual machine.
This service must not be used unless an I/O callback procedure has been installed for the given port using the Install_IO_Handler or Install_Mult_IO_Handlers service during initialization.
Port
Specifies the number of the I/O port for which global trapping is to be disabled.
This service has no return value.
The system applies to current global trapping state for each new virtual machine as it is created. When the system first starts, global trapping is enabled by default.
Flags
Enable_Global_Trapping, Install_IO_Handler, Install_Mult_IO_Handlers
