I connect my tower reset cable to J18 on board but reset function does not work
Maybe a faulty reset button or cable?
when I try to reset from keyboard ctrl+alt+alt screen turns black and wait
Not sure what could cause this. Try replacing the battery on the motherboard.
I installed wapos to my os4, I try to play wipeout demo, but it crash
In the documentation for the OS4 WarpOS wrapper, you'll see that it says only well-written, system-friendly stuff will work. Wipeout isn't. It's hard-coded for some sort of hardware banging. There's a workaround for MorphOS, but not OS4.
and whats the config of cpu power jumper (J17) for 750cxe cpu
I have no idea. What AmigaONEs shipped with that CPU? Is it an SE model? It sounds like the system is working, however, so I'd suggest not messing with it.
