[tulip] Recognizing the new driver at bootup

[Phil Barone]

Hi All,
  I sure appreciate all the help so far. Talk about confusing. See some
notes about what I have done to get this far at the bottom of this email.

 My question utimately is how to get my RH7.0 box to function correctly with
my cable modem. I am reading the cable modem how-to but am stuck.

  First how do I get my eth0 interface to be recognized at boot time? It
seems that what I am doing with the modprobe eth0 is causing eth0 to be seen
for the moment but as soon as I reboot, eth0 disappears. See below to see
what I've done so far.

What is the standard way of making eth0 available after the reboot?

1.) Do custom install of RH 7.0, using all components(kernel development is
I think the key here).
2.) Get copies of tulip.c, pci-scan.c, pci-scan.h, kern_comapt.h. Put them
in a empty directory, hint: /usr/src/modules
3.) cd /usr/src/modules
4.) Using the compile instructions at the end of pci-scan.c and tulip.c with
the following slight modifications.
  a.) for pci-scan.c do:
kgcc -I/usr/src/linux/include -DMODULE -D__KERNEL__ -DEXPORT_SYMTAB -Wall -W
strict-prototypes -O6 -c pci-scan.c
  b.) for tulip.c do:
kgcc -I/usr/src/linux/include -DMODULE -Wall -Wstrict-prototypes -O6 -c
tulip.c
 NOTE: Both compiles generated some warnings, not sure if the are any real
problem as the .o's were generated, they are as follows:

5.) Copied the .o's to ../net using:
 install -m 644 pci-scan.o tulip.o /lib/modules/`uname -r`/net
6.) Did a depmod -a
7.) Added an entry in /etc/modules.conf: alias eth0 tulip
8.) Did a modprobe eth0
9.) Now what!

Thanks again.
