This past week I purchased a lovely Dell C6100 unit on ebay, come to find out it is unable to take any official dell updates for the BIOS or BCM module. As my unit had BIOS version 1.04 (from 2009) I was unable to upgrade my CPU’s to hex-cores. After some research, I found out the reason was because my “C6100” was actually a DCS model. DCS models are re-branded or resold C6100’s that are not registered under dell. You can test for a DCS node by checking the service tag on dell’s website. If it returns not found, chances are you have a DCS model. But, after spending a while on the internet I was able to update both my BIOS and BCM firmwares to the latest dell releases!
First things first, this method for updating is not supported by Dell nor 2nd hand vendors so if you break anything, its your fault. There are some mentions that this method for updating will only work on C6100’s that have the “asset tag” field available in the BIOS, even if it’s empty. If your C6100 BIOS does not show any asset tag field at all, then you may be entering risky territory.
Now lets get on to the fun flashing!
NOTE: I am not responsible for any bricked or damaged units. If you are unsure of doing this process, then do not proceed!
- On your PC, use Rufus to format your Jump Drive and install MS-DOS for FreeDOS. (I Recommend FreeDOS)
- Next, Download and Place the contents of the c6100.zip file on the Jump Drive.
- Plugin your Jump Drive into one of the C6100 nodes, and boot to the Jump Drive. You should be at a DOS command prompt.
- First update the BIOS by going to C6100/BIOS and then running “FLASH.bat”
- Now be patient, flashing can take a minute or two. Once it is done, reboot the node.
- If all goes well your node will reboot with the updated BIOS! Now, boot the Jump Drive again.
- When at the DOS prompt again, now go to C6100/BMC and run “FLASH.bat”
- Again, wait for the update to complete. Once it is done, shutdown the node, then restart it.
- Congrats, you should now have your BIOS on version 1.71, and your BMC on 1.33! You will have to repeat this process on every node if you want to update the entire C6100.
