BIOS image for the S300CA motherboard, revision 2.0, supplied as an 8 MB .bin file. Matching the revision matters, so confirm that the PCB silkscreen reads REV 2.0 before flashing; a dump from another revision may not boot. The image size corresponds to a 64 Mbit SPI flash chip, and it is written with a hardware programmer when a board shows no POST or after a failed update. Keep a backup of the original chip so serial and other system data can be restored afterwards.
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.
How to open a .bin 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 →
