Hi DHD,
Thanks for your help.
I've already tried.
If I put # before vender in grub.conf, I get a different mac address at each boot, but I get an IP address from DHCP server.
If I remove it, I get the right mac address without correct IP (169.254.... self attributed).
If I try to install with Synology assistant I get an error message.
I seen, in the excel file, that uppercase and lowercase don't give the same result.
I've tried both results, you must use uppercase.
Do you have any idea?
Thanks.
X.
