Flash, just fyi, the plan for SUU 7.0 is to post a single iso on the ftp site (my idea btw), so that customers can use an ftp donwloader like filezilla to download the entire iso in one shot. The location of the ftp file will be listed on the "additional information" section of the SUU dnload. 
I have a Dell 2950 and am trying to update the firmware/BIOS.  I downloaded the Dell Server Update Utility, but noticed there are more than one ISO if I browse other menus.  Do I have to download all the ISO and join them? Or is there another method that is faster? Thanks!
