That depends. Is the controller for the hard drive a PCI-based controller? On
most x86-based boxes, it is (and I'm not sure it's even possible to build an
x86 kernel that doesn't have PCI as a =y in the config). However, very old
units may still have ISA based disk controllers, and other archs may have other
I/O buses.

Same as above.
