BIOS image for the SW3-013 device on the P0KCC board, revision 2.1, an Acer Aspire Switch model judging by the numbering although the name gives no brand. The RAR is about 2.7 MB and should contain a flash image for direct SPI programming. Because dumps for revisions 2.0 and 2.1 exist for this board, read the revision printed on the PCB and pick the matching file. Back up the current chip before writing and verify the dump size corresponds to the flash capacity.
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.
