atleast you got a KP.
i was happily using 10.6.2 and i have spent weeks fine tuning it and everything, but i fought, i'll give updating ago. (never had luck with updating on tiger and Normal Leopard).
so i spent 3 hours downloading the update (slow Internet times)
and once it finally installed, i rebooted!
then again....then again,,,,then again.
Chameleon doesn't even try to load the partition. i tried to go into Verbose mode, by nothing loads (no code no nothing!). by this time, a through my keyboard out the window (it's half past 4 in the morning. and i start cursing.)

I don't know what the problem is, to not load the first bit of code?
anyway, i have installed the latest Chameleon 2 RC4 version, still no luck.
here my specs if they help:

Gigabyte GA-M61PME-S2 (Nforce 430 (Nvidia 6100))
Nvidia 9800GT
AMD 2.7 GHz athlon Black edition.

i'm using the Legacy kernel by the way. ;D
