Fast Data Access MMU Miss

[Eduardo Viruena Silva]

Hello, FreeBSD gurus!

We have a Sun Microsystem Blade 2000 computer.

I tried to install FreeBSD on it,
when I try to boot from my FreeBSD-5.2.1 CD,
the loader seems to start working and
suddenly it issues this message:

        Fast Data Access MMU Miss

and dies.

Do you have any idea of what is happening?
My disc worked ok in an old Sparc 10.

Thanks in advance.

        Eduardo Viruena.
