Hi ther!
I'm getting som warnings at startup of NetBsd , and i'm wondering what causes
it.
The warnings are, warning found rdb->sparespercyl(942) != rdb->nsectors(60) *
                  rdb->nheads(16).
                  warning lp->d_sparespercyl(18) not multiple of lp->d_ntracs
                  (16).

I have also problems when trying to start up X11, the problem then is
        /usr/libexec-ld.so: warning: libc.so.12.5: minor version >=7 expected,
        using it anyway.
and
        /usr/libexec/ld.so: undefine symbol "_poll" in Xinit: /usr/X11R6.1/lib
        /libXt.so.6.0

I'm new to UNIX so please help me.
