Expect the GRAPHICS(3) graphics adaptor (which is an EISA card)
there is no expansion card installed in my C180. The 2 PCI slots
are not occupied by expansion cards.

I don't have too much knowledge of the architecture of HP
workstations, but aren't NCR SCSI chips part of the PCI
architecture in ordinary PCs ? Of course there must not be the
same way to implement the SCSI chip in the HP architecture ! But
who knowns ...

On the other hand the C180 had a working HP-UX 10.20 as I bought
it weeks ago. So there must be a software solution for the DINO
problem.

No PCI device to remove (as an expansion card) ...

... but how about a firmware update ? My box has firmware
version 2.7. Is that o.k. so far ? Or is there a newer firmware
available ? The other questions is: Would a firmware upgrade
help to solve my problem ?
