Re: [Nubus-pmac-users] SMC9194 support on PB1400?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

OK, so I compiled the smc9194 support as a module and I checked=20
/etc/modules.conf to find out that the object file is at
/lib/modules/2.4.31/kernel/drivers/net/smc9194.o

Then I tried to insert it into the kernel using

# insmod /lib/modules/2.4.31/kernel/drivers/net/smc9194.o
SMC9194: You shouldn't use auto-probing with insmod!
mac9194: PowerBook 1400 identified - probing for SMC919x in slot D address=
=20
space
/lib/modules/2.4.31/kernel/drivers/net/smc9194.o: init_module:=20
Input/output error
Hint: insmod error can be caused by incorrect module parameters, including=
=20
invalid IO or IRQ parameters. You may find more information in syslog or=20
the output from dmesg

Any ideas? I don't really know where to go from here...
