Well, it seems before your new BIOS flash, you would hear two beeps when you started your PC. Now you do not hear any, right?
All motherboards I have worked with beep once or not at all when the PC starts and everything is fine. If you had two beeps, maybe something was not quite right, or the BIOS had a problem. If everything is fine with the new BIOS except the beeps are gone, I think that there is no problem.
The latest BIOS 0014 does remove the beep. I've confirmed this with over 10 DG41WV boards.
You may also want to check your memory speed. I bet it's at 800MHz and when you try to change it to 1066MHz, you'll run into POST problems.
This board is a poor design. I'm still trying to get the board to operate at 1066MHz. I've tried 7-7-7-18 to 24 and 8-8-8-18 to 24 and all will give memory error on POST. It will only take 800MHz.

always so nice when folks give the details!
Your processor has a FSB of 800MHZ.
The FSB can't run faster than the processor (but most faster memory will clock down)
