Are you able to verify that the bios has the correct contents with a read back ?

That is, often, if the bios chip is soldered in the reverse direction, the bios chip will be damaged. It should then be replaced. If it verifies then it should be ok to use / test.

You have some voltages on the board but check the voltage to ground at each large coil / inductor. If the voltage is not present, remove all power -> check the resistance to ground of that coil. It may be shorted.

Bios chip can be written and verified, I backup WD the chip before programming.
