The first and only one:

$ /sbin/fdisk -l /dev/sda

Disk /dev/sda: 2045 MB, 2045247488 bytes
24 heads, 49 sectors/track, 3396 cylinders
Units = cylinders of 1176 * 512 = 602112 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        3396     1996823+   e  W95 FAT16 (LBA)

I did, and then it booted FreeDOS.  Then I installed Syslinux, and now
it boots Syslinux.  Perfect.  But it still has the FRDOS signature in
the boot sector, according to the command quoted above!  How can it be?
