RAR archive of 1.54 MB containing BIOS files for the Acer Aspire 4333; the name gives no board number, version or chip information. Extract it with WinRAR or 7-Zip and check what is inside, whether a raw SPI dump or an update package, before writing anything. Raw dumps are programmed directly onto the flash chip with an external programmer to revive a board. Check the extracted image size against the chip capacity and save a copy of the original chip before flashing.
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.
