How to execute ROM Update Utility on ML370 G1?

I have a ML370 g1 with Ultra 3 disks that the SA5300 is calling out for firmware updates. How do I apply the latest firmware updates?

It seems to me that I must use the ROM Update Utility available on Smart Start 6.x but I can't boot this model from that can I? What is the alternative?

Thanks
