   I don't see anything like that in my Asus M3A78-EM BIOS. There is a    
   selection for Legacy mode, which doesn't make any difference (except    
   when it is off, the computer doesn't attempt to boot from a USB device   
   that doesn't have a boot record on it, which causes it to ask what to    
   do). My hang on USBOHCD.SYS seems to be caused by ACPI running with    
   /APIC. This board is based on an ATI chipset, which seems to be a    
   follow on from the NVIDIA chipset (Apparently, ATI bought NVIDIA), so    
   I expect that it has something to do with multiple (high and low)    
   interrupts being enabled.
