Is there a way to gather information as to when a BIOS on a particular server has been updated?

I'm not looking for the BIOS release date, I'm looking for the date in which the bios was actually updated.

I suspect some people updating BIOSes in our environment but since we don't keep a maintained list of incoming/existing BIOSes its hard to tell if someone has changed it recently.

afaik, you could only determine this by checking the filesystem for the existence of update tools or images, and see when they were executed or accessed - unless cd or usb were used, then no. bios doesn't store a modified-date, only revision info – pete May 9 '14 at 17:26

Should be in the DRAC system logs on the Dell. Have you checked there?

Look for iDRAC log entries similar to the following: Updating firmware for Server BIOS 12G to version 2.2.2. - Successfully updated the Server BIOS 12G firmware to version 2.2.2. - Version change detected for BIOS firmware. Previous version:2.1.3, Current version:2.2.2 – joeqwerty May 9 '14 at 22:21
You realize, of course, that it is fairly easy to clear the log out. Thus this method is not necessarily foolproof. – mdpc May 10 '14 at 5:10
Sure it isn't. But you'll see the date it was cleared. – mfinni May 10 '14 at 16:39
