MSI MS-7295 archive, a zip of 5.22 MB. Nothing besides the board number is given in the name, so revision and contents remain unknown; the size suggests more than a single BIOS image, though that is not confirmed. MS-7xxx is MSI's internal desktop board code. Verify the revision silkscreened on the PCB before using the material to trace signals, check a short or find test points. For firmware, use an SPI programmer and keep a copy of the original chip first.
