Raw 4 MB BIOS image for mainboard 6050A2454801-MB-A01, an Inventec board number with no laptop brand or model stated in the name. The BIN can be written straight to the SPI flash with a programmer such as a CH341A or an RT809 series tool. Find the model by matching the 6050A number on the PCB silkscreen. Confirm the flash chip on the board is 4 MB, since a mismatched size will not fit, and read and save the original contents first to keep serial and 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 @bioshub. Enginerys does not host this file.
