In FreeBSD, the boot loader file is [.filename]#/boot/pxeboot#.
After [.filename]#/boot/pxeboot# executes, the FreeBSD kernel is loaded and the rest of the FreeBSD bootup sequence proceeds, as described in crossref:boot[boot,The FreeBSD Booting Process].
+[NOTE]
+====
+For UEFI PXE based boot, the actual boot loader file to use is [.filename]#/boot/loader.efi#.
+See the below section crossref:advanced-networking[_debugging_pxe_problems,Debugging PXE Problems] on how to use [.filename]#/boot/loader.efi#.

This section describes how to configure these services on a FreeBSD system so that other systems can PXE boot into FreeBSD.
Refer to man:diskless[8] for more information.
