Good job. You can sleep a bit more sound. SuperDuper is also a full backup solution I find very easy to use.

I saw your post about distros and kernels.

I only added the Voodoo kernel as you mentioned you already were using it. It offers some features which are a no brainer for AMD users. AMD machines need to applications patched and it does it on the fly. Makes life a lot less troublesome.

I use it on my Aspire one because most of my other machines are AMD and so im failure with it. It does perform some other useful tasks such as "Blacklisting" certain files which give us osx86 users problems. Now I you should have disabler.kext which also performs the blacklisting function. I added it as a precaustion. There is an Alpha version of the more recent Voodoo Kernel that Im starting to use on my aspire one just so that I can provide them with feedback on bugs I might find.

With the disabler.kext file you should be able to run the vanilla kernel from apple. Just remember the kernel requires two other files to be of the proper version. System.kext and Seatbelt.kext must be of the same version in order for the machine to function properly.

If you are interested in trying out the vanilla kernel you will need to round these files up. You could download the 10.5.8 delta "not combo" update and use a program called Pacifist to extract them.

What do I do after having the delta update downloaded and Pacifist is installed on my system?

Make a folder on your desktop and use pacifist to open the Update. You will then be able to navigate through and pull the three files you need.
mach_kernel
system.kext
seatbelt.kext

Make sure your current kexts and kernel is backup up and then you can install the kexts using KextHelper or by the methods explained in my previous posts.

You can install the kernel by typing the following in Terminal (Note the ~ and replace FolderOnYourDesktop with yours)

Code:

sudo su
cp -r ~/FolderOnYourDesktop/mach_kernel /mach_kernel
chown root:wheel /mach_kernel
chmod 644 /mach_kernel

Reboot using the boot-flag cpus=1

If you can't reboot we can restore the previous files as they should be backed up.

Should the cpus=1 flag be entered every time or can I make it do it every time some way?

There is a file called com.apple.boot.plist in /Library/Preferences/SystemConfiguration
Drag it to you desktop and open it up.

You should see something like:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Kernel</key>
    <string>mach_kernel</string>
    <key>Kernel Flags</key>
    <string></string>
    <key>Timeout</key>
    <string>5</string>
</dict>
</plist>

Find:

Code:

<key>Kernel Flags</key>
     <string></string>

and add the boot-flags here so in your case it would be:

Code:

<key>Kernel Flags</key>
<string>cpus=1</string>

Generally while Im setting up a machine I add -v to start up in Verbose Mode that way I can see whats going on. so

Code:

<key>Kernel Flags</key>
<string>cpus=1 -v</string>

Save the file and then drag it back into the folder. It will prompt you to Authenticate and then ask you if you want to overwrite the file. Do this and it should work fine.
