Unable to install on Alienware m17x

[BlackSun]

Hi, I try to install Freebsd 8.1 (amd64) on my laptop since a few days now and the only screen message I get from booting the CD is this (I copyed everything in case anyone could see something I missed) :

that is where it get stuck. My current hardware setting :

laptop : Alienware m17x

Thanks for your help!
