ho già postato, speriamo...
@all
nuovo aggiornamento...
in attesa di una prometheus.library 3.x,  sono riuscito a trovare online la versione 1.0b6 del 11.03.2005 della  openpci_8139.device, che necessita della openpci.library 2.0 e quindi adatta per la prometheus.library 2.5.
Con questa ultima situazione se do in pasto al Wizard di GENESIS di OS 3.9 la openpci_8139.device con il suo file di configurazione (imostato 0 per la autonegoziazione), ottengo il seguente requester a video:
"openpci_8139.device No Bus Master Capable"
quindi questo sta a significare che se questa scheda Prometheus non è stata aggiornata per il PCI Bus mastering e DMA da Matay, non posso usare gli OpenPCI driver ???   
 (dovrei ripassarmi il concetto, ho un 30 e lode in Architetture dei Sistemi)
ecco il log (Voodoo3 e scheda di rete RTL8139):
