Firmware for the Toshiba Tecra C50-C, part number PS571U, with board identifiers FLESSY2 and A4227A in the name. The image is described as having its ME region fixed and is an outimage, meaning a ready-to-write output dump. The RAR is 8.81 MB, which fits an 8 MB SPI flash. Technicians write this kind of file with an external programmer to cure boot loops or ME errors. Back up the original chip first, since it holds machine-specific data such as serial numbers and the MAC address.
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.
