BIOS image for the Lenovo ThinkPad T400 with board marking MLB31-9, packed as a 2.91 MB RAR. The name states an 8MB flash size and the tag NEW, which likely marks a newer or updated dump, though no version is given. Use it to restore a corrupted BIOS chip with an SPI programmer and clip. ThinkPad dumps can hold machine-specific data, so read and save the original first, confirm the chip really is 8 MB, and check that the board marking matches before writing.
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.
