I have a customer who wishes to use 2 nics in his G4 (os9.1). The problem is that once the second nic is installed, the computer won't go into low-power mode(sleep) all the way (the power fan keeps spinning), and once the machine has been awoken, there is an error stating that the pci card does not support removal of bus power...or something like that.

Is there a work around? Are there any Mac specific nics that would support full sleep mode? I've used smc and farallon cards with the same results.

All wake on lan features are disabled

Thanks
