@marksouth2000: Thank you, I read this other solution on the forum but here the problem is another, I mean, after a full install on the hd I used remasterpup2c.sh script to remaster Puppy 2.11 base with software I installed on, which are: TuxMath, TuxType2, GCopmris, SuperTux, TigthVNC by rarsa, Translate-Menu by MU.
Now, at boot time I had that error above and don't know why. I'm trying to put again row 54 in rc.sysinit but it seems the same thing. Now, my last attempt is to create again the iso always with the same script without a vnc connection but directly on the pc, but it seems the same thing.
Help me ! ;-)
