I just took a peek at the bf24 "config" file to check and here is what I
found. The code for the 8139 chipset (the 8139too code) is compiled
into the kernel so there is no need to insert a module for most 8139
based NICs. There is also a "8139cp" support compiled as a module. If
your install is NOT recognizing your existing 8139 chipset, you might
try inserting this other module and see if it recognizes it. As I
understand it, there are a few "mfg mods" to the 8139 that require
this... All of my 8139 based NICs (on cards on PCI bus) have been
automatically picked up during install of the bf24 kernel. I didn't
have to install any modules at all to get it going for a "network" install.
The same is NOT true of the "tulip" driver. It is only compiled as a
module in the bf24 kernel. You will have to install the "drivers" from
either the driver floppies or from the CD, whichever you use, and
install the "tulip" module before you can bring up the LNE100TX.
Finally, you can always upgrade to the 2.4.18 kernel via "apt-get" and
install the kernel-image package for that version. You would do this
from a "working" 2.2.XX kernel. It is entirely modular, so you will
have to insert ALL the modules you will need for your NIC(s) as well as
for getting ext3 support. This is how I made my initial transition to
the 2.4.18 kernel. There are a few "gotchas" in doing that... like
using initrd and inserting the modules etc. It DOES work, but it might
take a few tries, so keep your 2.2.XX kernel available as a back-up boot
route... <grin>.
