I have this patient arrived with a burned pcb, I tried several times to read the rom separately but the external reader I have tells me "empty chip", I have not yet tried to solder the rom on a donor pcb, but if the chip was empty, is there a way to adapt a patient rom on this model, has anyone had similar experiences?

Is this your PCB?

There appears to be a linear 3.3V (?) regulator (Q2 near SATA power). I suspect that it powers the SDRAM and ROM. If so, then the ROM has a good chance of surviving an overvoltage.
Were any of the TVS diodes shorted? Was the motor controller burnt?

I don't think you can write the ROM through a PC3000 utility. I think you can sometimes get lucky and move the NVRAM to a donor baord with the same ROM version or you need to move the chips physically.
