BIOS package for the Lenovo ThinkCentre M9860T desktop built on the IS6XM motherboard, archived as a 1.96 MB RAR. No version or revision appears in the name. Technicians use dumps like this to reprogram the SPI BIOS chip with a clip and programmer when the PC stays on a blank screen or fails after an interrupted update. Verify the board marking reads IS6XM and save the original chip contents first. Check that the image size inside the archive matches the flash device capacity.
