BIOS dump archive for the Lenovo ThinkPad T460p, LCFC board NM-A611, with BT463 also given in the name, packed as a 15.4 MB RAR. Contents are not itemised, so extract and check the image size against the SPI flash fitted to the board, since a mismatched image will not fit. Use a programmer such as CH341A or similar to write it, and always read and save the original chip contents first, as serial number and other system data are stored there. Confirm the NM-A611 marking on your PCB 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 @laptopbios21. Enginerys does not host this file.
