thanks techy for reply me but my pcb3bx was modified to 4.5 but my real problem is how to modify the pcb in order to programm spi flash devices like atmel 26df161 and others spi flashs
because i'haven't the id of the chips i mean spi flashs . the reading erasing and programming.
thanks.

You have to decrease voltage on SPI socket 25xxxx Vcc down to 3.6V.
Here are different methods to do on basic pcb3b - apply 2 diods after Vcc transistor, reduce programmer voltage after 5v regulator.

thanks ezo for reply me if you have a diagram or schema it would be gratful.
thanks.
