Firmware archive labelled only with board number 6050A2355301-MB-A05, 819 KB in RAR form, with no device model or version named. The 6050A numbering belongs to Inventec, an ODM supplying several notebook brands, and A05 denotes the board revision. Its contents are presumably a BIOS image meant for SPI programming, but should be inspected after extraction. Match the full number on the PCB, back up the existing flash before writing, and verify the file size equals the chip capacity.
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 @biosarchive. Enginerys does not host this file.
