	Well, Dev give me the hint to fix the problem.

	I already had configured the DMA transfer speed to 5 mb/s

	The thing was a jumper on the host (Ultrastor 14F)

	Jumper Block 13, 3-4 was OUT, wich means Host Adapter initiated 
	sync negotiation. It has to be IN, wich means target initiated 
	sync negotiation .

	And that was all the thing. Thanx to everybody
