BIOS archive for the MSI CR500X notebook, motherboard MS-16831 version 1.2, a small ZIP of about 547 KB. MS-xxxxx is MSI's own board numbering, printed on the PCB with the revision. At this size the archive likely contains a compressed image or an update file, so check what is inside before programming. Repair use is reflashing the SPI BIOS chip with a programmer when the laptop stays dead or shows no display. Match the MS-16831 number and ver 1.2, keep a backup of the existing chip, and confirm the image size equals the flash capacity.
