iATKOSv7 restarts during installation

[sanric]

Hi there, It's the first time I try to install OSX on my PC so please don't flame me
Got this hardware:

• MoBo: Abit LG-95C
• CPU: Intel Core 2 Duo @ 2200 MHz
• Chipset: Intel i945G/GZ
• Video: OnBoard Intel 82945G Express Chipset Family

with a pair of HD (in the first one there is XP in a single NTFS partition and the second one has a single FAT32 partition).
If I try to install iAtkos with the -v option it tells me it can't write the install log to any disk and then suddenly appears something like "System halted. The system should reboot now) followed by a sudden reset.
Have I to format it to hfs+ manually? I've read this motherboard should be simple to install osx.
How can I achieve this?
Thanks to all for the kind replies.
