The Intel Support article here: Desktop Boards — Troubleshooting BIOS issues
States that it is applicable to the DZ77GA-70K.
But I don't think that the battery can be removed with a screwdriver.
Just wanted to note.

- Unplug the power supply.
- open chassis taking all necessary precautions to avoid electrostatic discharge and personal injury
- locate CMOS jumper **see image below
- move the jumper from 1,2 to 2,3
- plug in the power supply and boot the system
- after post the setup runs automatically
- press F9 to restore defaults
- save and exit
- power down system and move the jumper back to original position.
Yes, that actually worked, so thank you.
Is that why the battery tray is different, to discourage people from actually removing the battery?
If that's the case, I think the support article should be updated.
Glad to hear it worked!
I don't know the answer to your question about the battery tray, though.
Okay, I think its time to better illustrate the issue at hand ;-)
I searched for some pictures (hope the hotlinking works) and made some myself of neweggs flash viewer thing.
So, here are the direct links:
1. Classic mainboard with battery tray I used to know
2. Another one. Please note the metal latch.
3. Latch and tray with battery removed would look similar to this
4. This is a current Z77 based mainboard, which has been released recently
5. Close up of the battery tray. The latch is closed. Also a current generation mainboard.
And now the Intel board:
6. No latch, but a plastic cover on top of the battery
7. Same board, slightly different angle.
The difference is quite easy to see.
I would like to hear from Intel about this design choice ;-)
