You are absolutely right.

I'll look at it ASAP.

They are  working  fine  here  (*)  on  three  boards  (2  x  labeled
"IceCube+", 1 x "LITE5200").

(*) - some PCI cards cause problems, for example a 3C905C  card;  I'm
pretty  sure  it  is  a  hardware  issue,  but so far it has not been
confirmed by Motorola yet;  for  USB,  you  may  have  to  short  L15
("below" the USB connector)

Yes, I know of some cases. But too many things are failing on MGT5100
hardware anyway.

It has been my impression that the  strategy  is  to  get  things  in
quickly, and to fix them later?

The software required `Windows 95 or better', so I installed Linux.
