PS2 Keyboard on laptop...not working even though worked during install dvd

[malayzn]

So I have a few questions using ideneb 10.5.5 and when I boot the DVD for install....
So many features work like brightness hot keys and my keyboard (ps2 integrated laptop) but after the install brightness doesnt work and same with my keyboard there ws suppose to be a ps2 fix but I dont see it in the fix menu when customizing install
gonna try 10.5.4 ideneb and see how that goes

but any tips?

Also whats the difference in the kernel versions?
9.5 vs 9.4 any difference?
9.4 I can get battery status
