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. > At loading stage ,boot loader need to move binaries from hard disk partition > to ram,does this work need pci's surport?
