ESXi bios update on host without OS installed.

If I have a new Dell R310 host that is going to be used for hosting a P2V virtual system, what would be the easiest way to update the bios on the host system for the motherboard and perc controller?  There is no OS pre-installed on the system so my guess is that I will need to boot it from CD and install the bios from this boot disk.

Always seems to be a headache to do it this way though.  Suggestions?

Thanks.

This is the only way to update the BIOS from a bootable source, I'm afraid, which means you would need to shutdown the ESXi server, and update the BIOS. There is no support in ESXi to update the BIOS, unlike ESX.
