Did you try with the BIOS recovery? Unplug the hard drives.
Recovery with CD-ROM
Intel® Desktop Board DP35DP
No, there are not. First of all, CMOS is not used for either BIOS or configuration storage (give or take the odd place where the BIOS still clings to CMOS (the result of BIOS bugs, IMHO), witnessed by the fact that removing the CMOS battery can make a difference). The BIOS, Onboard Video OpROM and ME Firmware, as well as the BIOS configuration, are all stored in a flash IC. Secondly, the flash can only be updated using the normal and recovery BIOS update processes; it is secured against all other methods.
I can only suggest that you retry the recovery process. In the absence of any output, wait at least a half hour (killing power after 10 minutes may have been the thing that corrupted your flash).
Sorry I couldn't be more helpful...
