BIOS image for an Acer laptop on the Quanta DAOZQAMB6C1 board, the O being a typo for zero, so the code reads DA0ZQAMB6C1. The RAR is small at 775 KB, so check whether it contains a full flash image or only the BIOS region. ZQA is the Quanta project code with revision C. The file serves for reprogramming the SPI chip with a programmer when the board fails to start. Verify the PCB number, read and keep the original chip data, and confirm the binary size matches the installed flash.
