BIOS image for the L305D on board 6050A2175001-MB-A02, 1 MB in size with no file extension. The 6050A prefix follows Inventec board numbering, so the motherboard was designed by Inventec for the brand that sold the laptop. The dump should be a raw image for an 8 Mbit SPI flash written with an external programmer. Check that the PCB shows the same number and A02 revision, back up the original chip, and make sure the file size matches its capacity.
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.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
