BIOS dump for the Acer 4736Z read from a Macronix MX25L8005M2C flash chip, which the name lists explicitly. The 1.00 MB size matches that 8 Mbit part exactly. Technicians write this image back to the chip with an SPI programmer when the laptop shows no picture or loops at power-on due to damaged firmware. Select the correct chip type in the programmer software, back up the original first, and confirm the board version on the PCB matches.
