Password/RTCRST jumper location on Optiplex 790 SFF?

Hello all!

I have a recertified Optiplex 790 Small Form Factor that came with a CMOS setup password that I don't have. The system is operable; I just need access to setup. I'm having trouble locating the jumper(s) to open on the motherboard - they're not listed in the user's manual. Removing the CMOS battery didn't clear the password. Any ideas? TIA!

Try removing the CMOS battery for 5 minutes to let the it forget everything.

The password is stored in Non volatile I2C EEPROM.  Removing battery has no effect on this whatsoever.!
