fail to 'see' ethercard

[Yves Picard]

i own (among others) a ps/2 (model 8580-311)
i used aix 1.1 (freshly installed)
i've slot an ethercard (in slot #7 if that matter)
i used the reference diskette to have the board recognized,
i compile some kernel (newkernel in /usr/sys)
i even RTFM thouh it doesn't help very much, 
when invoking ifconfig net0 192.XX.XX.XX i get
IOCTL: no such interface.
does anyone out there use networking on thick ethernet, mount NFS directory ?

any help will be apreciatte.

email is picard at ilog.ilog.fr thanks.
