Working BIOS for the Toshiba Tecra C50-C laptop, part number PS565G, with board code FAEPSY4, in a 3.27 MB RAR archive and labelled 100 percent working. Such dumps are written to the motherboard SPI flash with a hardware programmer when the unit shows no video, loops on power, or fails after an interrupted update. Before writing, save a full read of the existing chip, compare the board marking with the name, and make sure the file size matches the flash chip capacity so the image fits.
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.
