Firmware read taken from a Sony VAIO MBX-189 motherboard, with M763 rev 1.0 given as the board designation, stored as a 2 MB raw binary. The read prefix indicates it was dumped from a working chip with a programmer rather than extracted from an update file. Sony MBX boards came in several M-series variants, so match both MBX-189 and M763 on the PCB. Flash it to a 2 MB SPI chip, and back up the current chip before writing.
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.
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 →
