Lenovo G510 laptop BIOS dump, second copy, 6.50 MB in .rom form. That size does not match a single standard flash chip, so the file may combine two chips, for example a 4 MB and a 2 MB part, or be a padded image. Inspect it before programming, because an image whose size does not match the flash will not fit. The name states no board number or revision, so check the PCB. Back up both original chips before restoring the firmware to a G510 that fails to start.
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.

A BIOS image as shipped by the vendor (commonly AMI) — often the BIOS region only, without descriptor or ME.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
