Method of pre-processing for dynamic removal of a graphics display device from a computing apparatus
First Claim
1. A method of pre-processing for dynamic removal of a graphics display device from a computing apparatus, the computing apparatus including a motherboard that has a device interface for coupling with the graphics display device to be removed, said method comprising the steps of:
- a) upon receipt of a command to remove the graphics display device, obtaining an address of the graphics display device to be removed based on the command;
b) notifying a driver module of the graphics display device to be removed to release system resources of the computing apparatus allocated to the graphics display device to be removed; and
c) notifying an operating system of the computing apparatus to inquire the driver module of a current state of the graphics display device to be removed so as to acquire a response from the driver module indicating that the graphics display device is in an unused state, thereby terminating use of the graphics display device to be removed.

Abstract
In a method of pre-processing for dynamic removal of a graphics display device from a computing apparatus, upon receipt of a command to remove the graphics display device, an address of the graphics display device to be removed is obtained based on the command. A driver module of the graphics display device to be removed is then notified to release system resources of the computing apparatus allocated to the graphics display device to be removed. Thereafter, an operating system of the computing apparatus is notified to inquire the driver module of a current state of the graphics display device to be removed so as to acquire a response from the driver module indicating that the graphics display device is in an unused state, thereby terminating use of the graphics display device to be removed.

5. A computer program product for a computing apparatus, the computing apparatus including a motherboard that has a device interface for coupling with a graphics display device to be removed, said computer program product comprising program instructions for causing the computing apparatus to perform consecutive steps of a method of pre-processing for dynamic removal of the graphics display device from the computing apparatus, said method comprising:
-
upon receipt of a command to remove the graphics display device, obtaining an address of the graphics display device to be removed based on the command; notifying a driver module of the graphics display device to be removed to release system resources of the computing apparatus allocated to the graphics display device to be removed; and notifying an operating system of the computing apparatus to inquire the driver module of a current state of the graphics display device to be removed so as to acquire a response from the driver module indicating that the graphics display device is in an unused state, thereby terminating use of the graphics display device to be removed. - View Dependent Claims (6, 7, 8)

9. A computer program product for a computing apparatus, the computing apparatus including a motherboard that has a device interface for coupling with a graphics display device, said computer program product enabling the computing apparatus to perform pre-processing for dynamic removal of the graphics display device from the computing apparatus, said computer program product comprising:
a computer readable storage medium comprising; a first code that directs the computing apparatus to determine whether a command to remove the graphics display device is received thereby; a second code that directs the computing apparatus to obtain an address of the graphics display device to be removed based on the command received thereby; a third code that directs the computing apparatus to notify a driver module of the graphics display device to be removed to release system resources of the computing apparatus allocated to the graphics display device to be removed; a fourth code that directs the computing apparatus to notify an operating system of the computing apparatus to inquire the driver module of a current state of the graphics display device to be removed; and a fifth code that directs the computing apparatus to acquire a response from the driver module indicating that the graphics display device is in an unused state, thereby terminating use of the graphics display device to be removed.
