Hi [NAME],   As suggested by Martin earlier, the only option now left is to replace the motherboard.
I have an R740 PowerEdge server that is bringing up the following errors on every boot. UEFI0036: Unable to initialize the iDRAC Shared Memory Architecture (SMA) interface. UEFI0285: Unable to send Secure Boot policy data to iDRAC because of an issue in the iDRAC Shared Memory Architecture (SMA) Intelligent Platform Management Interface (IPMI). I have followed the suggested actions to remove power for 30 seconds and restart. I have also run the iDRAC firmware update executable and the BIOS update executable, both of which completed successfully, but the error remains. What could be causing this error and what can I do to resolve it?[IMAGE]
