Thread Starter 
Just wanted to point this out to everyone with RDX200CF-DR boards:

RDX200CF-DR Announcement

I think I actually read this and on further examination find it to be so for the cryptic engineering statement above and the RDX200. We are testing to see what if any relationship might exit between battery removal and cmos jumper pin movement to the clear cmos position.

Knowing that the general consensus has been to remove the battery and move the cmos jumper at the same time to clear the cmos on a DFI board; it is suggested during the time while engineering is doing their checking to refrain from removing the battery JUST to clear the cmos. It should not be necessary to remove the battery when trying to JUST clear the cmos on the RDX200 board as has been presented as a step in clearing the cmos on previous versions of boards. Leave the battery in and just move cmos jumper to the clear cmos position with a/c power removed from the power supply should you need or have occasion to clear the cmos.

Even shorter version. If you should find yourself in great need to change out a cmos battery on a board only 2 months old, when batteries usually last for years; change the battery. If your procedure to clear cmos with previous DFI boards has included removing the 'battery' and moving the cmos jumper to clear position> leave the battery in the battery holder and move only the cmos jumper to the clear position with A/c power unhooked from the power supply. Leave cmos jumper in the clear position for a minute or two then jumper the pins back to the normal run position and repower up the power supply and on to the business of computering.

This in my best red-nake english, is what the cryptic engineering statement said. They are doing lab testing. They suggest I leave the battery in and not take it out if I am only clearing cmos. Move the cmos jumper only. If I want to change my battery; to change my battery. They will give me another cryptic statement later.

Now that is what I read and after further checking found I was correct. Later.

If you remove the battery with or without the clear cmos jumper OR have a BRAND NEW board - it both has an impact.
I initially didn't believe in the battery bit since I had the voltage bug with 2 boards without having removed the battery in the first place - one of the boards was a RMA board from DFi - the other one brand new board .

I guess someone @ DFI must have also used the battery removal procedure before the tested RMA board was sent to me

Yeah, thats where it was posted - H_G was told my the engineers in Taiwan.

Just wanted to make sure everyone knew
