BIOS dump of 2.00 MB labelled y45o with the tag org, which usually marks an original read taken from a working chip. The name does not state a brand, board number or chip, so y45o is the only model hint and should be confirmed against the actual machine. A 2 MB image matches a 16 Mbit SPI flash. Before writing it with a programmer, check the board number on the PCB, save the existing chip contents, and remember that serials or system data in the dump belong to the donor unit.
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 →
