Yep, you can either use the FrameBufferBase address from EFI_GRAPHICS_OUTPUT_PROTOCOL_MODE and write directly there, or you can use GOP->Blt() to do the drawing for you. You can define for GOP->Blt() the rectangular region you want to draw, so you don't have to copy the entire screen each time. -Varun ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.
