RAR archive of 4.95 MB holding a BIOS for a 450 G4 machine that, according to the name, has its password removed, meaning the dump was modified to clear a supervisor or power-on password lock. No brand or board number is stated in the name. Extract the archive and check the image size against the flash chip before flashing. Such unlocked images are written with an SPI programmer; save the original chip contents first, since serial and configuration data may be stored there.
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 @biosfilebins. Enginerys does not host this file.
