Finally had the guts to install all the kext and upgrade my MSI McWindTosh from 10.5.4 to 10.5.6. Actually, the process is not that difficult. The complete tutorial can be read and followed here. To make it simple, first you must have a USB mouse and keyboard available. Connect both the USB mouse and keyboard and make sure it will work with your MSI. Then download the needed files such as OSX86 Tools, Vivarey's 10.5.6 upgrade pack and also the Mac OSX 10.5.6 Combo update pack. After ensuring both the USB mouse and keyboard are working, install the Mac OSX 10.5.6 Combo update pack. After the complete installation, your display will go back to 800 x 600 and both the keyboard and trakcpad will stop functioning. Within the Vivarey's 10.5.6 upgrade pack, there are three folders named Display, Keyboard and Trackpad. Within the Display folder, there are First and Second folder. Install all the 3 kext within the First folder, using OSX86 Tool (the install kexts button). Make sure you reboot the netbook after each kext installation. After finishing installing all 3 kexts, then install the GMA file in the second folder (don't need the OSX86 Tool, just double click). At the end of this, you will get back the 1024 x 600 screen resolution. Then install the kext in the keyboard folder and trackpad folder one by one, with restarting the netbook after each installation. With all these 3 installation, you will get back both the keyboard and mouse again.
Finally, do a software update again, to look for any new updates from Apple. Then with the 10.5.6 already installed in my netbook, I proceed to install ILIFE 09.
However I noted that the headphone jack is not working well, in which the netbook sound is not diverted into the headphone when it was plugged in. Found the driver for this, which is VoodooHA. Please feel free to download it and find the instruction on how to do the installation from here. For a short method, please open the/System/Library/Extensions folder in your OSX. Then find the AppleHDA.kext and remove it (or delete it). Please make a backup before deleting. Then install the new kext, ie Voodoopower.kext in the same folder and do a restart of the netbook. With this new kext, the headphone will work if any headphone plugged into it. However the internal microphone including the external output for the microphone will not work still. The only solution for this, is to buy a USB microphone and do the VOIP calls using this USB phone.
So, that is the final jigsaw for my MSI McWindTosh until someone find a driver for the internal microphone.
