Ok, I installed Snow leopard without any kind of problem. Quite everything works. But now I have 3 issues:
1, I can only boot with mod cd inserted.
2, I don't know how to update (now I'm on 10.6)
3.My graphic cards doesn't work well (It's a Ati Mobility Radeon HD 4330 and I had the ID).
I do not understand the part where the guide says: "Step 1: You will need to find out the PNP ID for your features you want to work, such as Ethernet, Wireless, Graphics, etc. This is one of the most important steps!!! Do NOT skip this step, or you will go through many pains trying to figure your IDs out when things don't work out-of-the-box.
From Windows, download Unknown Devices (linked below; download version 1.2 for XP, and the beta for Vista/7) and open it. Then look for things such as VGA-Compatible Controller, Ethernet Controller, etc. as shown in the linked screen shot. Click the plus box for the controller and for PNP ID and write down the four numbers/letters after VEN_ and DEV_. If Unknown Devices doesn't work, use the [font=inherit !important][font=inherit !important]Device[/font][/font][font=Verdana, Geneva, sans-serif] Manager in Windows; you simply double-click the hardware, choose the Details tab, and either choose Device Instance IDs (XP) or Hardware IDs (Vista/7).[/font]
[font=Verdana, Geneva, sans-serif]From Linux, open the Terminal and type lspci -nn > pciids.txt. This will save a document called pciids.txt in your home folder where you can easily access it."
What is it needed for? I do not find the PNP ID (Now I am on Windows 8 Consumer Preview)[/font]
