Firmware for the Lenovo ThinkServer TS250 tower server built on the IQ1X0MS motherboard, revision 1.0, packed in an 8.9 MB RAR. It allows recovery of the BIOS SPI chip when the server fails to start after a failed update or firmware corruption. Server boards sometimes carry more than one flash device, so identify which chip the image belongs to before programming. Save a backup of the existing contents with a programmer, confirm the revision on the board, and verify the file length matches the chip.
