Found the jumpers on the mother board. System rest and working again.
For my Power Edge R710, I downloaded the linuxIso.iso (Bootable ISO 2017-07-17_14-51-22 ) and created a boot cd. The update seemed to proceed as expected, but during reboot, the screen is now blank and no longer displays the prompt configuring memory or anything else.I am able to browse to the iDrac Console and do things like reboot the system but I am unable to launch the virtual console.  (running Windows 10 and Java 8)How do I fix this? Is there some onboard jumper I can use to reset the bios or do I need to take another approach?
