I'd like to experiment with this, since having MacOS initialize the SONIC
would be a reasonable interim solution for the Quadra users until the PROM
problem has been solved. Under System 7.1, the ethernet driver appears to
be loaded even when booting with extensions off (the transceiver LEDs flash
a couple of times).
The kernel mentioned above unfortunately is too PB550-specific to work on
my Quadra, so I will need to build my own kernel. I have the March 30
sources available and would appreciate if someone could send me the original
SONIC sources.

Thanks in advance. Best wishes,

           Nico
