Thanks for your help Donald. I have some answers to your questions...

'modprobe tulip' does not work even if I do 'modprobe pci-scan' first. I have
run 'depmod -a' and the modules.dep file DOES reflect the dependency of tulip.o
on pci-scan.o. So I don't understand why modprobe doesn't work. That's why I
was using 'insmod'.

I have to use dhcp with our LAN. I have compiled and installed the latest
version of dhcp client deamon for Linux 'dhcpcd-1.3.19-pl1'. So with dhcp
running I was told not to assign an IP address.

Actually I tried to specify the irq and the io_addr parameters given in the
/proc/pci file using:

ifconfig eth0 irq 11 io_addr 0xfc00

but I get the IFMAP errors like I did using 'ifup eth0':

SIOCSIFMAP: Operation not supported
SIOCSIFMAP: Operation not supported

I'll try the tulip-diag program and let you know what happens.

Thanks again for your help
