Firmware package for a board labelled X133K revision 2.0, a 4.69 MB RAR archive. The name indicates an 8MB BIOS image together with an ITE embedded controller firmware, so both the main SPI flash and the EC can be restored. No brand is stated. Before writing, read and keep a backup of the original chips with a programmer, check the BIOS chip really is 8MB, and verify that the board marking and revision correspond to X133K Rev 2.0.
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.
