Original BIOS read from a Sony VAIO MBX-219 motherboard, a 1.00 MB binary corresponding to an 8 Mbit SPI flash; org typically means an unmodified dump from a working unit. No revision or version is given. Sony identifies VAIO boards by MBX codes printed on the PCB, so confirm the match before use. Use the file to recover a board with corrupted firmware via an external programmer, backing up the chip first and verifying the written data.
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 @bios_laptop. Enginerys does not host this file.
