PX-130a+PX716a+Dell 8300



got a new Drive (PX-130A) today the problem is that i forgot how to reset the Bios(I think it was alt e,alt f,alt b or so but it don’t work so it must be wrong!!).DMA setting was DMA Mode 4 for the PX-716a now it’s 1 and only PIO Mode for the PX-130A.

Operating system : Windows XP V5.01.2600 Service Pack 2
