A quick update.
I arrived home just now. Go through the wizard quickly and then Leopard logs in. I haven't found the Chinese input method yet. Thus, I have to use English. Fortunately, my pcbeta ID is English.
I have checked System Profiler and found CI/QE is enabled. However, the sound card is not recognized yet.
I know the Mac logo can be replaced. But it is still a headache to a Mac beginner like me. I will be back when I resolved the encountered problems.
Thank you for your consideration so far.
To lijie:
P5B has two BIOS options related to boot sequence.
One is Boot Priority, the other is Hard Disk. From Boot Priority, you can order the boot device and the hard drive is listed as one item. If you have more than one disk. You need to set the Hard Disk option. The 1st Drive you set in the Hard Disk option is the boot disk listed in Boot Priority.
Hope this makes me clear.
