Success update to 10.6.4 with these spec:
phenom 9850 be
770 chipset
gtx 260
lan and sound working
i installed SL on external usb hdd so i can use it at home n office.
i'm using blacknight 10.2.0 darwin kernel(10.6.4).
on intel cpu -force64 still got the error(10.6.3).

before update, i can boot on intel cpu at my office, even after i delete sleepEnabler, still KP on intel. but using -force64 no KP, it just restart by itself after loading nvidia detection. at office i had gt 8500.

why on 10.6.3 i can boot my hdd on intel and amd machine using blacknight 10.2.0 kernel but when update to 10.6.4 i only can boot in amd?
