This FreeBSD port can additionally operate on plain files containing
a FAT image, thus requiring no special privilege. The program relies
on mtools to perform the manipulation of the FAT filesystem.

\fBSyslinux\fP supports the loading of initial ramdisks (initrd) and the
bzImage kernel format.
+.SH NOTES
+The boot sector and LDLINUX.SYS rely heavily on the operation of
+the \fBsyslinux\fP program to run correctly. In particular,
+\fBsyslinux\fP patches the boot sector with the exact location on
+the disk of the first sector of LDLINUX.SYS, and also it patches
+the file LDLINUX.SYS with the exact location on the disk of each
+additional sector of LDLINUX.SYS itself.
+.PP
+This means that if you want to prepare a new bootable disk, it is
+not enough to duplicate the boot sector and LDLINUX.SYS, but you
+really need to run \fBsyslinux\fP to update the sectors addresses.

+The version of \fBsyslinux\fP used on FreeBSD makes use of the
