Steps I took to update from 10.6.1 to 10.6.2:Before
updating first backup your kernel. If you forget this, your 1000HE won't start.
cp mach_kernel mach_kernel_1061
chown 0:0 mach_kernel_1061
After the reboot, you have to boot from the backup kernel. When you're in the chameleon bootloader type the name of the kernel you want to start. In this example it's mach_kernel_1061. You'll see what you type in the bottom of the screen.
After your 1000HE is booted, you're running 10.6.2 with the 10.6.1 kernel. Now we're going to install the patched Atom kernel (this kernel tells OSX your Atom is an Intel core solo processor).
Download the kernel from the forum:Patched mach_kernel 10.2.0 for Atom-based netbooks, Dirty bithack
Unzip this download to the desktop.
Unfortunately one of the installed kext can't work together with this new kernel, so you'll need to replace the SleepEnabler.kext too.
Download SleepEnabler 10.6.2 from the forum:SleepEnabler for 10.6.2, (Only for Kernel 10.2.0)
Unzip this download to the desktop too.
Now we're going to install the new kernel. In terminal type the following commands:
mv mach_kernel mach_kernel_orig1062
cp ~/Desktop/mach_kernel /
chown 0:0 mach_kernel
chmod 644 mach_kernel
Now we're going to install the new SleepEnabler.kext.
Open the Finder and go to /Extra/GeneralExtentions.
Copy the SleepEnabler.kext from your desktop to /Extra/GeneralExtentions
Rebuild the kext cache in /Extra with the program UpdateExtra in the folder /Extra.
After a few minutes your system is ready to boot from the new kernel. Reboot your system, in Chameleon type -f to rebuild all the kext and enjoy!
