Solution found! I was able to get the BIOS updated! Since you confirmed it was a "standard" c1100 and, I thought I would to ignore the error and push the BIOS upgrade without the "file ID" check. I downloaded the DOS image BIOS image, unzipped it and copied the files to a FreeDOS bootable USB, then edited the F.bat file to ignore the file ID by adding /X to the end of the line: #F.bat Original Afudos S99C3B25.ROM /P /B /K #Add /X to ignore File ID mismatch error Afudos S99C3B25.ROM /P /B /K /X It successfully pushed the new BIOS and successfully rebooted after with the updated BIOS.  Thanks for pointing me to the DOS "floppy" patch method! -Didj
Have several Dell c1100 PowerEdge 1U servers that need to have the latest BIOS installed to patch Metldown Specter vulnerability.  I used the service tag number to find the correct BIOS and used the Linux .bin file.  It runs, identifies the server as a c1100, then says that it's not compatible with a c1100.  Screenshot below: [IMAGE]c1100 bios not compatible with c1100 Anyone have ideas?   Thank You! didj9k    
c1100 bios upgrade is incompatible with c1100
