I upgraded the BIOS of my S1200V3RPM (XEON E3 1265L V3) to https://downloadcenter.intel.com/download/26301/Intel-Server-Board-S1200V3RPL-S1200V3RPO-S1200V3RPM-... 3.03.0006
To do this, I insterted a USB stick with the new BIOS, booted to the internal EFI shell and then the BIOS upgrade started by itself. It ran through to the end without any issues.
I then power cycled the machine to reboot and now it does not boot anymore. No beep, so POST screen, nothing.
How can I get back to a working machine?
Here are our recommendations for the issue:
Power cycle the system again by removing cables and pressing the power button for 10 seconds and remove the CMOS battery for 1 minute. Install the battery back and try to POST.
Test the system on a minimal configuration, swap memory modules between. Test the system without processor and memory looking for beep code sequences.
