Raw BIOS image for a C850 series board, tagged with the number 10028 and the word sabz, and marked okok by whoever tested it. The name gives no CPU or chip detail beyond that, so treat 10028 as the board identifier to match against your PCB. At 4.00 MB it fits a 32 Mbit SPI flash and is loaded with a hardware programmer such as a CH341A. Always read and store the existing chip contents before writing, and check the board revision, since dumps for related boards differ.
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 @biosbigarchives. 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 →
