At booting stage,kernel need to detect the hard device before mount it, does this work need pci's surport?
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?
Same as above.
