BIOS dump for the Lenovo ThinkPad E450 on AIVE1 motherboard NM-A211, an LCFC design, for the SR23Y processor variant without a discrete GPU, as the name states BEZ GPU, meaning without graphics. Use it only on integrated-graphics boards, since discrete versions need different firmware. LCFC is Lenovo's in-house ODM with NM-xxxx numbering. Match the PCB number and CPU marking, back up the existing SPI chip with a programmer, and confirm the image size fits the flash before writing.
