Firmware archive for the Dell Inspiron 7577, marked with BIOS version 1.9.3 and sized 4.59 MB in 7z format. The board number is not listed, so identify the motherboard and its flash chip before use. A known version helps when a unit is stuck after a failed update or when matching firmware for a replacement board. Flashing is normally done with an SPI programmer such as a CH341A or RT809. Read and archive the existing chip first, and check that the extracted image is the same size as the flash device before programming it.
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.
