Lenovo BIOS dump for board NM-B244, an 8 MB binary image that matches a 64 Mbit SPI flash chip. The name marks it as tested and as having OBRAM disabled, which is generally done to get past memory-related boot problems on boards with soldered RAM; the exact edit is not described. NM-xxxx numbers follow the LCFC pattern used for Lenovo boards. Back up the original chip with a programmer such as a CH341A before writing, and confirm the board number on the PCB matches.
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 @ITHINKHS. Enginerys does not host this file.
