FreeBSD-6.2, 7.0-BETA1 boot on Lenovo X60

[Balgansuren Batsukh]

Hello All,

Last few days I try to boot FreeBSD-6.2, 7.0-BETA1 boot CD using USB CDROM 
drive on Lenovo X60.

It give kind of assembler code non-stop flow over screen.

Can't boot system and some times give BTX halted message after CPU register 
code ES=....,....

Is there any way to boot/install FreeBSD-6.2/7.0-BETA on X60?

Regards,
