100227228 ROM location?

[LostDataSa]

Hi
Received 3 hp BD03685A24 SCSI, 2 of them with damaged PCB 100227228, looks like from overcurrent. I have a donor PCB, but don't know where the ROM is.

Did you check the fuse and TVS diode?

I think this is an old Seagate Cheetah 10K
Maybe someone else may confirm.

I managed to image all drives, a simple hotswap of pcb did the job.
