Hi,
Sorry, I was long. I tried to boot my 7025-F40 with this kernel
http://www.solinno.co.uk/7043-140/files/2.6.9-rc2/ (the novga version) but
the I have a kernel panic while booting. Here's what is printed out on my
terminal :

********************************************************************
After that I tried with a stock 2.6.16.19 kernel thinking that perhaps this
machine was integrated, but noting appears on the terminal (not even the
"Linux/PPC load:" statement...) and the server reboots, and reboots again...
Is it from any help ?
Is there something to do to have a working 2.6 kernel on an 7025-F40 ?
Thanks a lot
