I've been a fan of the arranger board for a while. A lot of great info and discussions. Never had a need to post till now. Here goes . . . I own a PSR 9000 and think it's a great board. Well, the OS I bought the board with was 1.01. I went to Yamaha's PSR page . . . http://www.yamaha.co.jp/english/product/pk/pk2000/products/psr9000/psr9000.htm

I decided to upgrade to the 2.11 OS. I followed the instructions and copied the info to 5 floppies & followed the installation directions on my PSR 9000. After loading is completed, the LCD shows "Completed". Then I press [EXIT] twice and my PSR-9000 is supposed to restart with the new OS version. Well, what happens at this point is it hangs and all I get is a blue screen . . . a new form of the blue screen of death :-(

Can anyone tell me how I can get my OS back. Or maybe a link somewhere at Yamaha where I can get help?

I can be such an idiot sometimes.

BTW It's a the PSR 9000 is great board. I've owned several over the years. This is the best so far. I'm hooked.
