Unlocked BIOS image for the Sony VAIO VGN-TX56C built on the MBX-153 motherboard, provided in a 1.33 MB RAR. The password protection has been removed so a locked notebook can be returned to normal use. Flash it to the BIOS chip with an SPI programmer, reading and saving the original contents first in case something goes wrong. Confirm the MBX-153 board number and that the image size matches the flash chip capacity, since a mismatched file will not fit.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
