Firmware package covering the ASUS K550J and X550JD that disables soldered memory, allowing boot with a module in the RAM slot only. Repair shops apply such a modified BIOS when onboard DRAM fails tests or causes no-POST symptoms. No revision is listed in the name, so check the motherboard label and compare against the stock image. The 1009 KB ZIP must be unpacked and the image written with an SPI programmer. Back up the original chip and verify the flash size matches before programming.
