Power Edge R710 Bios Update Failure

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?
