ATA and APIC IRQ conflict

[David Naylor]

Hi,

I am trying to install FreeBSD on a gigabyte board (based on nForce 650i 
chipset (with MCP51 controller)) however no SATA hard drives are detected.  
However, if APIC is disabled then I have access to the hard drives (and only 
one CPU).  It has been suggested that it is an IRQ conflict (or something 
else related to APIC).  

Could someone please point me in the right direction so that I could try fix 
this problem (i.e. how to change the IRQ of the ATA drivers or where to 
fiddle with APIC to try get it to work?)

Thanks in advance

David
