Lenovo BIOS image for the DP510 board, LCFC number NM-B041 revision 1.0, intended for a 16 MB flash chip and packed in a 17.5 MB ZIP. NM-xxxx numbers belong to LCFC, the Lenovo-owned design and manufacturing unit. Technicians write such files with a hardware programmer when the BIOS is corrupted or a board will not power on correctly. Verify the board marking and revision on the PCB, back up the existing chip contents, and confirm the chip on the board is 16 MB, otherwise the image will not fit.
