BIOS image collection for the Acer Aspire 4820T, labelled with the Quanta-style project code ZQ1. The RAR is about 1.60 MB, so the archive may hold more than a single raw dump. Check the contents and the chip capacity before choosing a file to program. A technician uses such firmware to restore a board whose flash has become corrupted after a failed update or a power fault. Read and store the original chip first, and make sure the project code printed on your motherboard really matches this one.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @bios_laptop. Enginerys does not host this file.
