BIOS dump for the Lenovo ThinkPad T460 on the LCFC board NM-A581, revision 3, marked as tested and working. LCFC is the Lenovo design arm that uses the NM-xxxx numbering seen on ThinkPad mainboards. The 7.48 MB RAR is for reflashing the SPI BIOS chip with a programmer when the laptop will not post or is stuck after an update. Even with a tested image, back up your chip, keep the original serial data in mind, and confirm that the board revision and flash size match.
