Raw BIOS binary labelled 2230CS, 2.00 MB in size, matching a 16-Mbit flash chip. The name gives only this model designation, without brand, board number, revision or firmware version, and it should not be assumed identical to the 2230S images. Write it to the SPI flash with a programmer to recover a non-booting board. Before doing so, read and preserve the original chip contents, confirm the chip is a 2 MB part, and verify the board is the matching model.
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 @biosfilebins. 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 →
