BIOS dump for the Lenovo ThinkPad T490, machine type 20N2, with BIOS version N2IET87W given in the name. Packed as a 7.49 MB RAR, it is useful when a T490 board will not POST, loops at power-on or needs its SPI contents replaced after a failed update. Open the archive and identify which file goes to which flash chip by size before writing anything. Then read and save the original chip with your programmer so the serial number and board-specific data can be restored if needed.
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 @biosfilebins. Enginerys does not host this file.
