I have 2 systems using the same MOBO with multiple drives connected 
to ATA100 and have had no problem with installation since 8.0 when the 
driver for onboard ATA100 was added to the kernel.

You may need to update the system BIOS but my guess would be that you
have a component installed in the PCI Slot 2.
That slot shares an IRQ with the Promise Controler.
Move that component to another slot and  you should be OK.
