This is sad... I've killed two motherboards with this, and some brain child at tech support sent me e-mail this morning inviting me to try again. (Like THAT's a good idea)
Using a bootable CD, it "said" the flash completed correctly, (It lied)
My 1 month old E-521 is now on it's third motherboard, Running Win-XP pro as the 1.0.3 bios seems to cause interesting problems with Vista for me at times. But at least it's usable and the sound actually works.
No floppy drive to use in taking the route y'all seem to be having some success with. And definitely no wish to go out a buy one just to use it once. I already have enough money invested in this system.
