Linux on sam640LE

[musa]

Hi all
I just set up my new sam640LE with Os4.1fe and Morphos and everything works perfectly except the sound card.
I have a question about Linux that I hope someone can help me with.

Can anyone tell me if the text in my menu.lst file is correct

delay 3
default 0

title VOID for Sam460LE
root idea 0:1
kernel /boot/uImage-460 root=/dev/sda3 console=ttyS0,115200 console=tty0
dtb /boot/sam460ex.dtb

I have an ext3 partition on the first hard drive partition 3. I have used rsync to transfer the contents of a mounted void.img to this partition.
In (root) / I have my menu.lst and parthenope reads it and forms a menu item.
I am using the 4.5.0sam460ex kernel to boot
in /boot I have
canyonlands.dtb
sam4g0ex.dtb
syatem.map
uimage-460
I press enter in the menu item but void does not start.
Someone who can figure out what I'm doing wrong
Thanks in advance
Musa
