Main BIOS dump for the Acer Aspire 4349 built on motherboard DA0ZQRMB6C0, revision C, as stated in the name. The DA0 prefix with MB is the Quanta numbering pattern, so the board was made by Quanta for Acer. The file is 4.00 MB, matching a 32 Mbit SPI flash chip. Technicians flash it with a hardware programmer when the laptop has no display or loops on power-up. Compare the number and revision silkscreened on the PCB with the file, and save a copy of the original chip before writing.
