[9fans] problems booting a new install

["Ezequiel Reyes" <ezequiel.reyes@newhotel.co.cu>]

I just installed a plan 9 system on sdC0, configured the plan9.ini on 9fat
and the system boots well to the point of showing:

user[none]:

I guess there is no user defined after install so I go on with none and this
is the output:

kfs ... File system main inconsistent
Would you like to ream (y/n)? bad nvram key
bad authentication id
bad authentication domain
    tag : Tnone; expected Tdir; addr = 2
kfs init7 : FID1 attach to root
kfs 7: suicide: sys: trap: fault read addr=0x0 pc=0x0001cae4
version ... panic: boot process died: sys: write on closed pipe
pc=0x00007858
dumpstack disabled
cpu: exiting

these are the main variables in my ini file:

bootfile=sdC0!9fat!9pcdisk
bootargs=local!#S/sdC0/fossil

there was a nobootprompt as well in the .ini file I took has a reference for
modification with value: local!boot/bzboot
But I saw no reference to it on the plan9.ini man page. So I tried comenting
and uncomenting it, no results.
Is it a problem with my root not defined in the ini? Need I use rootdir or
something? which would be the path?
