ML310 with FastTrak SX4000 not working

[Oliver_28]

Hi,

I just got a new HP Proliant ML310 with internal Ultra ATA-100 IDE storage adapter and I put a FastTrak SX4000 raid controller in it (supports raid 5). The problem I have is that for some reason I cannot run both controller at the same time. If both are activated I get the following error message when I try to boot: PCI parity error on slot 00
I have allready tried to swap the fasttrak card and also changed the IRQ, but the only way to boot is to deactivate the internal ATA controller.
Any idea why I cannot run both?

Thanks
Oliver
