BIOS for a ThinkPad X260 board at revision 4.0, with the Management Engine region cleaned, supplied in a 5.30 MB ZIP. No board number appears in the name, so match the revision printed on your PCB before use. ME-cleaned images are commonly flashed when a board turns off after a set time, starts slowly or shows ME errors. Dump the original SPI chip first, then write this image with a programmer such as a CH341A and verify the write.
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 @biosfilebins. Enginerys does not host this file.
