Multiboot - NetBSD

NetBSD also supports GRUB multiboot specifications. Hence, it's very easy to boot the operating system up. The full specification is available here: https://www.gnu.org/software/grub/manual/grub/html_node/NetBSD.html.

Instructions for Boot

These are the instructions for setting up boot sequences for GNU/Linux. They are multi-boot standard procedures.

#1 - Search and Set Root Partition

You need to seek out your root partition via search command and set command for setting the root partition to it. You also need to load the part_bsd module.

grub> insmod part_bsd

grub> set root=(hd0,netbsd1)

#2 - Load the Kernel

Next is to load the kernel using knetbsd command. You can load it as follows:

# Basic

grub> knetbsd /netbsd

# With kernel arguments

grub> knetbsd /netbsd -s -v

#3 - Load the Kernel Modules

Next is to load the kernel modules using knetbsd_module_elf command:

grub> knetbsd_module_elf /stand/amd64/6.0/modules/ffs/ffs.kmod

#4 - Boot it

Once done, you can proceed to execute boot sequences using the boot command and release the boot sequence to that operating system.

grub> boot

That's all about multibooting netBSD.
