Holy computer
I do not own a sager 5680 per se, but I have a laptop that looks identical, but has a different name "Whitebox CL5".
I was annoyed by the video display "bug" with WinDVD playback, so I checked this forum.
Halleluja!
I do not yet know if any thing is screwed ut, but the playback issue seems to be solved in WinDVD.
I used Winphlash and flashed from windows with "568R10s.wph", and I had no problems what-so-ever in the time right after flashing.
I have to get back to this thread if anything has gone wrong somehow, but right now everything seems OK.

(Will go watch the movie Gods&Generals now)
Edit: A few days later, I have had no issues that I am aware of after flashing the bios.
Edit2: Ok, a while later it is fair to suspect that I have one issue. My boot-up often result in a blue screen of death, with varying errors. Not a critical I guess, but somewhat annoying.
Edit3: Ok, the blue screen of death is gone, and I dont know why.
