Re: ethernet support in 2.2.20-20011202 kernel

Hi Ray,

You certainly hit the nail on the head there! I did some more digging on the net after your email and it 
seems that the standard debian download has a 2.2.10 kernel (well old). I used the 2.2.20 vmlinux... kernel 
file off the Sourceforge site and this works fine. It seems a little quicker overall than the 2.2.10 one and 
the ethernet driver (v0.4...) works just great. I can ping backward and forward between my PC laptop and mac 
with no problem.

On reflection, there are lots of pointer to the old kernel not being what I thought it was. However, as with 
most things when you are new to them, sometimes it is difficult to see the "wood for the trees".

One thing I would like to do now is to install the newer version of everything onto the mac (eg modules, 
etc). Especially since I now get lots of "module dependency" errors popping up during the boot (it can't find 
module.dep file in lib/2.2.20/). There is a patch that came with the other 2.2.20 files, but I don't know how 
to use that. I am also not completely sure which of the other files in the set of 2.2.20 files replaces the 
original debian ones (drivers, sysmap etc).

As usual, any help from anyone would be appreciated.
