The Dxx chips are at the back of the PCB under the Ram modules. Anyway, I have checked the complete SCSI chip against the 3x Jpeg files, which are very detailed, and the conclusion is: there are no broken traces or VIA's.
For that board I'm 90% sure the SCSI chip self is faulty. It noticed in FWB toolkit 2.0.6 than eventhough it recognises the hard drive, model and brand: it lists a wrong size. FWB says it's 64MB while it's a 80MB drive.
When I verify that with a good SE/30 board: it's indeed recognised as 80MB: this only adds to my case that the SCSI controller is faulty.
The other SE/30 board with dead SCSI was repaired quickly, I found 2x broken VIA's, repaired them with a wire and it was sorted.
Now I have to replace the SCSI chip: I did found one on Ebay, PLCC version, I hope this fits. But I don't have an SMD rework station to replace IC's.
Has anyone used this solution ? http://www.chipquik.com/
Have a look at the 40 seond youtube video on their website: it's very interesting how fast they can remove an SMD IC.
