Jbonpland, There are multiple ways of updating the BIOS on the R910. One of the easiest is using one of the Dell Update Packages, dependent on the OS used. There are some things to consider when updating the BIOS as well is how far behind it is, if the server is drastically out of date then it isn't recommended to go to the current version. It is best to walk the updates up. Now with updating the Raid Controller and Drac there is 2 answers. First is that with the iDrac you need to update it with the BIOS. If both are out of date then walk both up simultaneously. If you update the BIOS and leave the ESm far back then there can be a lose of communication between the two. So something to keep in mind. The second answer would be that with the Raid controller, if you are already going to bring the server down to update the other two then might take advantage of the maintenance window and update the server fully.  Let me know what OS you are using and I can get you the information needed.
