Acer Aspire E1-570G BIOS for Compal board LA-9535P, project Z5WE1, intended for a Winbond W25Q64FV flash chip, in a 2.85 MB 7z archive. The W25Q64FV is a 64 Mbit (8 MB) SPI device, so the extracted image should be exactly that size. Repairers program it with a CH341A, RT809 or similar tool, using a clip or a desoldered chip, to recover a dead board. Read the original chip first, confirm LA-9535P on the PCB, and verify the write after programming.
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 @biosfiles. Enginerys does not host this file.
