This is indeed 5 partitions.  The swap partition is used as a runtime
memory extension; the other partitions separate out parts of the directory
tree to limit the extent of damage in case of any disaster.  If one
filesystem gets corrupted, the others should still be OK.

When you install Debian, you can get dual booting by using LILO.  This is
my config file (/etc/lilo.conf):

boot=/dev/hda3
root=/dev/hda3
compact
install=/boot/boot.b
map=/boot/map
vga=normal
delay=50
# Linux - 2.0.32
image=/boot/vmlinuz-2.0.32
  label=linux
  append="mem=96m aic7xxx=ultra"
  read-only
# Linux - 2.0.33
image=/boot/vmlinuz-2.0.33
  label=linux2033
  append="mem=96m aic7xxx=ultra"
  read-only
# Win 95
other=/dev/hda1
  label=w95

This particular configuration allows me to boot Linux with either of two
kernel versions; it also allows for Windows95.

Important! 

  1  After changing /etc/lilo.conf, and especially after changing the
     kernel, you must run /sbin/lilo to update the boot map.

  2  Install any Microsoft product first; Microsoft has no respect for the
     presence of any other OS and is liable to overwrite the boot sector.

  3  Make sure you have a rescue floppy or a bootable CD.

If you don't want to risk using LILO you can boot Linux from inside DOS
with LOADLIN.EXE.
