Firmware dump for the Fujitsu D2990-A31 motherboard, GS 2 according to the name, stored in a RAR of about 2.7 MB. Fujitsu uses the D-number to identify its desktop boards, with the A and GS suffixes marking variant and revision. Technicians write such an image to the SPI flash with an external programmer when the board fails to start or a BIOS update was interrupted. Check the D-number and GS level on the PCB sticker, back up the existing contents, and confirm the file size matches the chip.
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.
