HOW CAN WE AWAKE ALL THE GIANTS OF THIS FORUM FOR SOLUTION OF OUR ISSUES?

Dear,
I am here for solution of a problem.
Last night I made some changes in BIOS setting of my DM800HD with telnet client.
I have changed DHCP setting to manual as 192.168.10.15 by disabling auto function.
Now the problem is that I can not re-flash my box with power button on starting. Power button is not working while pressing on power on. But it shows the address 192.168.10.15 and boots up.
It can not stops on pressing on power button, neither can not be accessed with telnet client.
But it can connect after full start within web-interface as well as with DCC.
Please guide me how to reset these setting as default so I can access BIOS settings again.
Thanks and waiting for favorable reply.
