Dell Server PowerEdge BIOS R730/R730-xd Version 1.3.6
23 Jun 2015

It includes several updates; among them:

_ Removed unused setup options.
_ Fixed an issue where Mellanox network card would not commit PXE boot in UEFI mode 
on Port 2.


I am not saying updating this firmware (still being call "BIOS" by Dell) will solve 
any particular problem. It is just intended to show, once again, that checking for 
firmware updates might be relevant when regards to booting.
