The syslinux program installs a linux bootloader on a FAT-formatted

filesystem or disk image. 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. WWW: http://syslinux.zytor.com/

+.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.
