The latest version on NetbookInstaller has been released. There are a couple of new features but mostly just updated kexts from the previous version.

Updated Chameleon. I’ve also included numerous patches which are detailed in the previous post.
(Partial) Support for 64bit cpus. For best results boot in 32bit mode (arch=i386). I’ll try to update the 64bit kexts shortly and post an update.
Updated the bootloader code so that when chameleon is installed, it no longer messes up windows installations.
Added code so that in the event of a system update, NetbookInstaller is automatically run on reboot.
NetbookBootMaker no longer patches the install dvd, instead it installs a kext to patch the dvd at runtime (like NetbookCD). This means you’ll probably want to restore the install dvd (this won’t be required in the future since the dvd isn’t modified anymore).
Added a recovery option for chameleon. Just type “recover” and a known good set of kext will be loaded, while /Extra/Extensions.mkext will be ignored.

How to update to 10.6.3: The only requirement is that you have NetbookInstaller 0.8.4pre (or later) installed. Once you update the system, NBI will be run automatically.

NOTE: If when booting, you see the NBI logo, do *not* restart. This is indicating that NBI is running and updating files (/Extra) due to a system change. There currently is an issue where restarts take a while after NBI is running, just wait it out, eventually it’ll reboot again and start up to your desktop.

NOTE2: There is no Asus 1201n support in this build, I’ll try to get one out shortly (this weekend) for it.

Work in progress for next gen of NetbookBootInstaller by Meklort

In order to simplify the NetbookCD install process, we need some way to patch the dvd *after* it’s been loaded up. There are a few different ways to do this, however the easiest way is to use a feature built directly into the kernel, XNU.

It turns out that if the RAMDisk property exists in the device tree, xnu will automatically setup and mount a memory device that was previously loaded by the bootloader (in our case, Chameleon). Chameleon already supports loading ramdisks, so I’ve modified it to load a second, “Postboot.img” ramdisk form the preboot ramdisk (only way to get it off of the previously removed cd), and then setup the correct properties for the kernel. Now, in the event that apple removes the automount feature in xnu, we can easily write a simple kernel extension that does the equivalent (by using the mdevadd function).

I’ve uploaded an example postboot image as well as the patches to chameleon. They could be a *lot* better, but they work. The uploaded patch includes the following changes:

Notifies xnu of a ramdisk, if it loads one.
Modifies chameleon to look for Extensions/10.x/Extensions.mkext in the ramdisk like it does in the boot drive. (This allows for one boot cd instead of two like the current releases).
Included some of the hibernation patches from netkas / pcefi 10.4.
Modifies the memory layout so that a larger ramdisk can be used (NOTE: this is *not* needed, I only used it so that I could boot PureDarwin Nano from a ramdisk).
The included patch also includes backing up the original dsdt (which has been used for some time with NetbookInstaller).
