MSI CR42 2M MS-1492 8MB BIOS&EC

BIOS .rar 3.10 MB Shared

Firmware archive for the MSI CR42 2M notebook on MSI board MS-1492, containing an 8 MB BIOS image together with EC (embedded controller) firmware. MSI uses the MS-xxxx pattern for its in-house motherboards, and a suffix digit often marks the exact variant. The BIOS goes onto the SPI flash with a programmer, while the EC file restores keyboard, power-button and charging control. Back up both original chips before writing, and confirm your flash chip is 8 MB so the image fits without truncation.

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.
