Firmware archive for the Sony VAIO VPCEH-111T, labelled with Sony board code MBX-249 and the Z50HR version string. Sony identifies its notebook motherboards with MBX numbers, so the MBX label on the PCB is the first thing to check against this file. The dump serves for reprogramming the BIOS flash with a programmer when the machine shows no image or loops on power-up. Read and keep the original chip contents before writing, and make sure the image size matches the capacity of the chip fitted on your board.
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.
