Raw 1 MB BIOS binary for the Compaq Presario CQ50 with Wistron motherboard 07241-2. Wistron boards are identified by five-digit codes with a revision suffix, printed on the PCB. Because the file is a plain .bin, you can load it straight into a programmer such as a CH341A or RT809. Make sure the flash chip is 8 Mbit, that is 1 MB, so the image fits, and that the board number matches. Save the existing contents before writing in case they contain unique system 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 @Datalvela_servicios. Enginerys does not host this file.
