Ok i thing i did something wrong while posting. I'll post it again:

Since I have an SB600 chipset I injected the kext that can be found on this forum for this chipset and now it detects both my ATA dvdrom and my SATA disk. However i now can't get past the NTFS partition detecting sequence...

@the rest: Does anybody else suffer from this? I have 2 NTFS partitions: 1 Windows RE OEM rescue partition and a large OS/storage partition. The intaller doesnt give any errors, not even in verbose mode. I can't just remove all of those partitions since it's actually my office notebook :-).

I also tryed installing through an USB IDE controller connected to an old harddisk while having the original one disconnected. Except for the poor performance, the OS crashes when it reaches the welcome wizzard. I get a totally crewed up graphical interface with nothing readable on it an stuttering sound... I thought having an ATI 2400 HD was a good thing since it's included in the *real* I Mac we have on the office...

Can anybody help me with this?
