No need to be sorry NoJuan999, I understand the risk involved when flashing. Thanks for the recovery information. However, I do not have a floppy drive or diskette to try it. I did try to use a bootable flash drive to see if it work and no luck. The system just simply refuse to do anything other than showing the power led when I press the power button. I already got the RMA # for it, hopefully they'll fix it without asking much. But I am too afraid to try it again, though. Can anyone else confirm the success flash?
I just hate to hear about anyone bricking a MB, especially if I did the Mod. They wshouldn't hassle you if you RMA it. Just tell them you were flashing their Original Bios Update when it happened. These MSI boards usually work well but sometimes they can be a bit finicky. Yours was the first PR400 MB I have done so no one else has tested it. You might just want to play it safe and use the Loader by Daz.
Thanks again for the response. I would have to say that you did a fantastic job here with so many successful mods. I've successfully flashed 4 different systems with the bios I got here. I am no way complaining. The only reason I post my result is to caution other this might be an issue. BTW, do you mind elaborate a little about the Loader by Daz. I actually don't know what it is.
