	+Due to size constraints, one may need to set
	+.Va LOADERSIZE
	+larger than the
	+default 500000, although often loader is under the 500k limit even with
	+this option.
	+Setting
	+.Va LOADERSIZE
	+larger than 500000 may cause
	+.Xr pxeboot 8
	+to be too large to work.
	+Careful testing of the loader in the target environment when built with a larger
	+limit to establish safe limits is critical because different BIOS environments
	+reserve differing amounts of the low 640k space, making a precise limit for
	+everybody impossible.
	+.Pp
	+See also
	+.Va WITH_LOADER_PXEBOOT
	+for other considerations.
