◆ EFI_VGA_MINI_PORT_SET_MODE

typedef EFI_STATUS(EFIAPI * EFI_VGA_MINI_PORT_SET_MODE) (IN EFI_VGA_MINI_PORT_PROTOCOL *This, IN UINTN ModeNumber)

Sets the text display mode of a VGA controller.

Sets the text display mode of the VGA controller to the mode specified by ModeNumber. A ModeNumber of 0 is a request for an 80x25 text mode. A ModeNumber of 1 is a request for an 80x50 text mode. If ModeNumber is greater than MaxModeNumber, then EFI_UNSUPPORTED is returned. If the VGA controller is not functioning properly, then EFI_DEVICE_ERROR is returned. If the VGA controller is sucessfully set to the mode number specified by ModeNumber, then EFI_SUCCESS is returned.

Parameters

[in]	This	A pointer to the EFI_VGA_MINI_PORT_PROTOCOL instance.
[in]	ModeNumber	The requested mode number. 0 for 80x25. 1 for 80x5.

Return values

EFI_SUCCESS	The mode number was set.
EFI_UNSUPPORTED	The mode number specified by ModeNumber is not supported.
EFI_DEVICE_ERROR	The device is not functioning properly.
