Working BIOS for Quanta board DA0Y0AMB6C0, revision C, made for a Winbond W25Q64F flash chip. The W25Q64F is a 64 Mbit (8 MB) SPI chip, so the extracted image should be exactly 8 MB. Program it with a CH341A or similar tool using a clip or after removing the chip, and select the correct chip in the software. Read and save the existing contents first, and check that the board code and revision C match the PCB.
