+====== Running Multiple Operating Systems ======
+===== Booting MINIX 3 Directly =====
+MINIX 3 can coexist on a hard disk with Windows or Linux. The hard part is figuring out how to choose which OS to boot. Here are a few hints:
+  * [[http://www.woodhull.com/newfaq/faq/bootother.html|Using the MINIX boot monitor to start other operating systems (May be outdated)]]
+===== Using GRUB 2 to boot MINIX 3 =====
+GRUB 2 stores its configuration in a file called //grub.cfg// (usually ///boot/grub/grub.cfg//) but you shouldn't edit it directly as it is generated with the information given in ///etc/default/grub// and the files in ///etc/grub.d//.\\
+To boot MINIX 3 with GRUB 2 there's two alternatives:
+==== add a menu entry for loading the MINIX bootloader ====
+Edit ///etc/grub.d/40_custom// (you will probably have to be root to do so) and add the following code:
+<code>
+menuentry "MINIX 3" {
+        set root=(hdX,Y)
+        chainloader +1
+}
+</code>
+Here are some examples of GRUB's naming convention for the disks and partitions:
+  * (hd0,1) - first primary partition on first hard disk
+  * (hd0,2) - second primary partition on first hard disk
+  * (hd0,3) - third primary partition on first hard disk
+  * (hd0,4) - fourth primary partition on first hard disk
+  * (hd1,1) - first primary partition on second hard disk
+  * (hd1,2) - second primary partition on second hard disk
+  * and so on
+<!> Note: GRUB 1 and GRUB 2 have different naming conventions for partitions.
+Alternatively, if you want to use GRUB to boot MINIX directly:
+==== add a menu entry for MINIX ====
+The entry should have this shape:
+<code>
+menuentry "Minix Latest" {
+        set root=(hd0,3,1)
+        multiboot /boot/minix_latest/kernel rootdevname=c0d0p2s0
+        module /boot/minix_latest/mod01_ds.gz
+        module /boot/minix_latest/mod02_rs.gz
+        module /boot/minix_latest/mod03_pm.gz
+        module /boot/minix_latest/mod04_sched.gz
+        module /boot/minix_latest/mod05_vfs.gz
+        module /boot/minix_latest/mod06_memory.gz
+        module /boot/minix_latest/mod07_log.gz
+        module /boot/minix_latest/mod08_tty.gz
+        module /boot/minix_latest/mod09_mfs.gz
+        module /boot/minix_latest/mod10_vm.gz
+        module /boot/minix_latest/mod11_pfs.gz
+        module /boot/minix_latest/mod12_init.gz
+}
+</code>
+==== [optional] un-hide the boot menu on startup ====
+Edit ///etc/default/grub// and change ''GRUB_HIDDEN_TIMEOUT=0'' to ''# GRUB_HIDDEN_TIMEOUT=0''.\\
+(You can also press //shift// during GRUB's startup to show the boot menu.)
+==== generate new grub.cfg ====
+Run **''grub-mkconfig''** as root to rewiew the new configuration.\\
+Run **''grub-mkconfig -o /boot/grub/grub.cfg''** as root to overwrite your old //grub.cfg// with the new configuration. \\
+(change the path to your //grub.cfg// if it differs from the one given above)
+===== Using GRUB 0.9x (GRUB1) to boot MINIX 3 =====
+To have GRUB1 boot MINIX, you can just add the following lines to your GRUB config file (typically ///boot/grub/menu.lst//):
+<code>
+title Minix
+rootnoverify (hdX,Y) # (hdX,Y) is the disk and partition where you install Minix
+chainloader +1       # tells GRUB to call Minix's boot loader
+</code>
+Here are some examples of GRUB's naming convention for the disks and partitions:
+  * (hd0,0) - first primary partition on first hard disk
+  * (hd0,1) - second primary partition on first hard disk
+  * (hd0,2) - third primary partition on first hard disk
+  * (hd0,3) - fourth primary partition on first hard disk
+  * (hd1,0) - first primary partition on second hard disk
+  * (hd1,1) - second primary partition on second hard disk
+  * and so on
+<!> Note: GRUB 1 and GRUB 2 have different naming conventions for partitions.
+===== Using a Boot Floppy or the CD-ROM =====
+If you don't want to use a multiboot loader, you can use a MINIX 3 boot floppy or the MINIX 3 CD-ROM to boot MINIX.
+Don't forget to change the //Boot Order// in your BIOS if necessary. You want to boot from the floppy/CD before booting from disk.
+<!> The following instructions are relevant to MINIX 3.1.x; the new boot loader uses a different syntax (and there are no boot floppy any more).
+==== Using the MINIX 3 CD-ROM ====
+  * Insert the MINIX 3 CD-ROM and boot
+  * Login as //bin//
+  * Type //shutdown// to get back to the MINIX 3 boot monitor
+  * Now type:
+<code>
+boot c0d0p0
+</code>
+to boot from the operating system image file on controller 0, drive 0, partition 0. Of course, if you put MINIX 3 on drive 1 partition 2, sub-partition 0, use:
+<code>
+boot c0d1p2s0
+</code>
+and so on.
+==== Using a Boot Floppy ====
+If you have a legacy floppy disk drive, you can boot MINIX 3 by inserting your new boot floppy and turning on the power.
+===== Starting MINIX 3 from MS-DOS or Windows. =====
