BIOS dump for the UMA (integrated graphics only) version of LCFC board NM-A272, revision 1.0, used by Lenovo on the ACLU1 and ACLU2 platforms. Because a UMA board lacks a discrete GPU, firmware from the discrete variant should not be assumed compatible. NM- numbers follow the LCFC scheme. Flash the image to the SPI chip with a hardware programmer when the board will not boot. Back up the existing chip, verify board number and revision, and match image size to chip capacity.
