I haven't heard about folks trying it, but BootCamp should certainly work.

Just reporting back that my firmware update via Bootcamp XP on a Mac Pro went fine. Eventually. The first attempt went awry, and it took awhile to get XP to recognize the 990 on USB after that. I ultimately had to rollback XP to a time before the firmware tool was downloaded to get everything nominal. Then it worked like a charm.

Guys I admire you all for the fortitude and perservence you all have for installing the new software...but I am shy to pull the trigger.
I realize that if I do have a problem that the Outlaw service department will stand by there product but although I have not read about that many problems with installing the upgrade I also have not read about that many Outlaws doing the upgrade and having all that noticeable difference.
I intend to sell my 990 in the future months once the new model comes out...hopefully in the next month or two. The person I am selling it to realizes that the new software will not be installed. He is happy with the product as is and knows that he can do the upgrading at a later date himself.

Notfamou did the Outlaws charge you anything for the installation and or correction to your 990?

Rubbersoul,

I did the firmware updating myself at home, so the Outlaws never actively figured into my situation.

Cheers,
Tim

One thing I haven't seen in this thread (unless I missed something) - what does the upgrade sound like? In which modes? better? no big difference? astounding improvement? etc?

I think the consensus was that there was improvement for 2 channel sound with some detractors.
