OK! i had have to:
-set the auto_action HALT
-set bootdef_dev dka0
-Initialize the sound with:
isacfg -init
add_sound
init
-add DE200-LE network interface with isacfg command:
isacfg -slot 1 -dev 0 -mk -handle DE200-LE -irq0 5 -
iobase0 300 -membase0 d0000 -memlen0 10000 -etyp 1 -enadev 1

-set boot_osflags as Multi User with "a" parameter

Now it's ok

Now the system seem to be OK, BUT after many time (40mins) the S.O. crash down and show the follow error:

halted CPU 0

halt code = 7
machine check while in PAL mode
PC = 19370
>>>

Any ideas about?

Not sure about this, but you might consider a firmware update.
This often has to be done when part of the hardware has been replaced.

now it seems to be ok.
the pc is on two days without falls
