Main system BIOS dump of 2 MB for the PLF PLR CSF CSR board family, UMA build, revision 2.1. Main means it holds the system firmware rather than the keyboard controller code. A separate 4 MB image with the same label also exists, so these boards may use more than one flash chip. Make sure the image size matches the chip you are programming, since a 2 MB file only belongs on a 16 Mbit part. Back up the existing contents first and check that the UMA, integrated-graphics layout matches the board.
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.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
