BIOS firmware package for the NEC PC-LZ750MSS, built on MSI board MS-13911 at version 1.1, supplied as a 2.57 MB RAR archive. The MS-1xxx numbering identifies MSI as the original board maker even though the machine carries the NEC label. Technicians use such a dump to restore a corrupted SPI flash with a programmer such as a CH341A. Unpack the archive, confirm the board number and revision printed on the PCB, compare image size with the chip capacity, and read and save the original contents before writing anything.
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 @biosarchive. Enginerys does not host this file.
