Firmware archive for an HCL machine using the Nvidia MCP79MVL-B2 single-chip chipset, packed as a 612 KB RAR. It is a different, smaller file than other MCP79 HCL archives, so compare contents before choosing. No laptop model or board revision is stated. The MCP79 combines northbridge, southbridge and integrated graphics. Extract, inspect, and confirm the binary matches the capacity of the flash chip, then back up the existing chip with a programmer before reflashing.
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.
