Yes, I think I can nail it now. One final clarification, do I use a
.config geared more to my machine, or am I supposed to do a "make

I haven't done this in a while and I'm still going thru the xconfig,
stripping out modules for hardware I don't have, but if I just transfer the
old ones in, they should work but will be building about 1400 modules

I just got the 2nd message about marking the subject line, can do, thanks.

Thanks Jason.


Cheers, Gene
