BIOS set for the Lenovo ThinkPad T530 on Wistron board 11222-3, supplied as separate SPI1 and SPI2 images. This board splits its firmware across two flash chips, so each file must go to its matching chip and not be swapped. The 5.17 MB RAR is used for programmer recovery when the laptop will not start or the firmware is corrupt. Read both chips before writing, keep those backups, and confirm that the image sizes equal the chip capacities and that the board label shows 11222-3.
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.
