 This happens on my P4 system too on an ASUS P4C800 with the PDC20378
 controller.

 More info:
 - If I enable the controller in the BIOS but have no drives attached (either
 S-ATA or P-ATA - I'm using P-ATA only because that's what I've got) the
 system boots fine
 - If I add just one disk, the system still boots fine (ad8 on ata4-master)
 - The problem happens when I add the slave drive
