i will try as much as possible, i don't know if it will help but here are some screenshot (made with my camera)
images are 700KB big, so i give only the URL
default boot : http://www.tout57.fr/leo/default.jpg

then i tried with the Extensions.mkext from CD (and removing the Extensions directory)
http://www.tout57.fr/leo/cd_ext_only.jpg => not beter

finaly i tried with the kernel from CD (because i installed the last one)
http://www.tout57.fr/leo/cd_ext_kern.jpg => kernel panic

i will try with extensions directory AND extensions.mkext and do a shot

really hope someone can help me...

edit
i try with Extension.mkext AND Extenstion directory with the installed kenerl (9.2) and here is a kernel panic too
