BIOS package for the Dell Vostro 3546, supplied as a RAR archive of about 4.54 MB. The name gives only the model, with no board number, revision or flash size, so open the archive and inspect its contents before use. Dell laptops of this kind are built on ODM boards whose number is printed on the PCB, and that number should be noted to confirm compatibility. Back up the existing SPI chip with a programmer, verify the read, and only then write the new image, making sure its size matches the chip.
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 @biosarchive. Enginerys does not host this file.
