Panel TypeInitialization
The VGA BIOS will issue INT 15h function call during POST. This function call allows the system BIOS to specify the panel type to the VGA BIOS. The system BIOS should get the panel type from GPIO pins before the VGA chip initialized, and pass this information to VGA BIOS through INT 15 Function 5F01h.
