[sNapie]

Hello,

i've downloaded the FreeBSD 6.0 release, and tried to install it on my 
sony vaio notebook, but the installation freezed on 38% of the importing 
of "doc" to "/".then i tried to install it on my normal PC, but it still 
freezed during the installation. even worse, is that i've downloaded the 
5.4 release and the same problem happened.
could you help me on that ?
Thank you very much,
