Toshiba BIOS dump labelled with the board code FLESSY2 and the identifier A4227A, delivered in a 4.63 MB RAR archive. The name does not give the laptop model, so matching the FLESSY2 marking on the PCB is the main way to confirm compatibility. Such an image is written to the SPI flash with an external programmer to revive a board with corrupted firmware. Before flashing, back up the existing chip, compare the extracted file size with the flash capacity, and expect that serial or system data may need restoring.
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.
