Firmware dump for the Acer Aspire 4733Z laptop, marked ok in the name, which suggests the uploader confirmed it working on a real board. The raw .bin is 1.00 MB, the size of an 8 Mbit SPI flash chip. Such images are flashed with a hardware programmer to revive a board with corrupted BIOS, no display or a boot loop. Save a copy of the original chip before writing, and compare the board number on the PCB with any known version for the model, since one model can ship on different mainboards.
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 @ComputerBIOSBinFile. Enginerys does not host this file.
