Dell C6220 BIOS & BMC Firmware (how to roll back to previous version)
I successfully updated the BIOS and BMC Firmware for our C6220 server. However now when boot, it keeps sitting at screen "Configuring Memory... Done" for at least 3-5 minutes before moving on to the boots detection, then there's a message states BMC version: FF.FF (instead of displaying the actual version)
I could not able to access the server via IMPI and found BIOS settings menu does not see BMC (message... BMC: Not Found). I suspect the either the BMC version 2.53 or BIOS version 2.5.3 or both on the support site is corrupted.
