BIOS archive for the ASUS GL502VY gaming laptop, mainboard revision 2.2, containing an 8MB image. ASUS typically names its boards after the model, so the GL502VY code with REV2.2 printed on the PCB is what should match. Technicians use such a dump to reflash a corrupted SPI chip with an external programmer when the laptop gives no display or loops on boot. Back up the existing chip first, because it may hold the serial number and system identifiers, and verify the chip is 8MB.
