Boot Image Negotiation Layer daemon

The Boot Image Negotiation Layer daemon (BINLD) server is the third stage of contact for preboot execution environment (PXE) clients.

After communicating with the DHCP server to obtain an IP address, and after communication with the PXE Proxy DHCP server to obtain the location of the boot server, the boot server is contacted to get the filename and location from which to download the boot image. The PXE client can return to communicate with the boot server multiple times in the course of booting if the client requires multiple files in its boot process.

The final stage in the PXE network boot is to download the boot image given by the boot server. The location of the TFTP server and the filename that is to be downloaded is given by the boot server to the PXE client.
