 +====== 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. =====
