Um...nevermind...It looks like A47 still supports the .iso creation, you just have to unzip everything first and run the dddp.exe file.  This launches a media creation utility, from which you can just pick ".iso"
I have a copy of version A43 of the Dell SAS/SATA Hard Disk firmware update utility, which was new in March of 2013, i see that A47 has just been released, but it doesn't seem to have any .iso included with it, and says that only windows operating systems are supported.  What happened to having a .iso included, and just booting to the CD, running all the updates, and THEN worrying about which OS you're on? i'm running CentOS, based on Red Hat Linux, and i can't get to the latest and greatest firmware.  Updating disks attached to an MD1000, direct-attached to a PERC6/E. I get that burning CD's is very 2004, but some of us still definitely prefer it to needing to install a windows OS in order to accomplish such a simple task as updating disk firmware. Anyone with info, please spill it here!
SAS/SATA disk firmware: where's the .iso?
