BIOS firmware archive for a board carrying Inventec / Foxconn style number 6050A2638901, labelled 15SBUK with MB revision A01. The name gives no laptop brand or model, so confirm the board number silkscreened on the PCB before use. The 3.73 MB RAR should hold a flash image meant for writing to the SPI chip with a programmer such as CH341A. Read and save the original chip contents first, and make sure the image size matches the chip capacity, otherwise it will not fit or boot correctly.
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.
