The first part

BIOS: Hardware detection, read CMOS boot sequence.

PXE: Self-booting, sending IP Request packets with a PXE identity , requesting IP addresses

DHCP: Provide network IP,tftp host address and boot file

Computer startup, self-test, self-booting,PXE get IP and FTP shared boot file and kernel.

Part II

FTP: Shared kernel boot file

pxelinux.0: is a machine boot file that instructs the client to download the default in the pxelinux.cfg directory to FTP file
