problem with ia64 installation cd

[Mario Beltran]

Hello.

I want to install freebsd 6.0 in my dell poweredge sc430 box

I downloaded  boot only and cd1 iso files from freebsd site.

but when i try to install it the box cant boot, i have a cd from freebsd 
6.0 but for i386 and boot perfect.

Also I downloaded iso files  from other mirros whith the same results :(

Is this a problem of files in the ftp sites?

does anyone have a clue to give me?

I need to install freebsd en this box

thanks in advance

Mario
