Upgrading firmware and BIOS without Windows/Redhat/Floppy

How would folks recommend upgrading the PERC 5/i firmware as well as the
BIOS on a PowerEdge 1950 that is running Ubuntu Linux?

All the downloads I've seen on the Dell site are either for Redhat,
Windows or bootable floppy, none of which I have in this case.

I do have a CDROM in the server as well as a USB floppy drive, but am
unsure if it's possible to boot off a USB floppy on a PE1950?

Unfortunatly the server is pretty far away from where I am physically so
I don't have the ability to test different methods before I go to the

I'm getting the following in dmesg when I boot on a PE1950 I bought in
04/2007 and not on one I bought in 10/2007.  I think the older firmware 
on the 04/2007 PERC 5/i card is potentially the problem:
