BIOS dump for the ASUS X441UB laptop, mainboard revision 2.1, intended for an 8 MB flash chip, stored as a 5.75 MB zip. The 8MB marking means the image should match a 64 Mbit SPI device, so check the chip on the board before programming. Technicians use such files to recover units that will not power on or display after a failed update, writing the chip directly with a CH341A or similar programmer. Confirm the X441UB revision silkscreened on the PCB and save a copy of the original firmware before flashing.
