They also stock the data store with operating system images and RSCD agents … The client broadcasts a DHCP packet asking for the address of DHCP servers (servers that can hand out IP addresses). PXE works with Network Interface Card (NIC) of the system by making it function like a boot device. If a DHCP server implementing PXE is found, the server assigns an IP address to the device and sends information about available PXE boot servers.
