It is possible to boot MINIX 3 over the network. This makes use of the PXE protocol supported in some network cards. The network card loads its boot files over network and boot the PC from these files.
PXE booting involves two machines :
This document will explain how to populate the TFTP root directory for booting MINIX 3.
Setting up a PXE server
Setting up a DHCP/TFTP server is outside the scope of this document. Check your operating system's documentation to learn how to set up a PXE server.
The boot-to-ramdisk image is suitable for booting over PXE. To generate the image, run
releasetools/x86_ramdisk.sh. The kernel and modules will be placed into
../obj.i386/work, move them to the TFTP root directory.
As with a hard drive installation, a boot loader is required to bootstrap the system.

Download the latest release of SYSLINUX at https://www.kernel.org/pub/linux/utils/boot/syslinux/. Extract the following files and put them in the TFTP root directory :
Create a directory named
pxelinux.cfg/ in the TFTP root directory. Inside it, create a file named
default with the following contents :
DEFAULT menu.c32 TIMEOUT 100 LABEL x86 MENU LABEL MINIX 3 KERNEL mboot.c32 APPEND kernel bootramdisk=1 --- mod01_ds --- mod02_rs --- mod03_pm --- mod04_sched --- mod05_vfs --- mod06_memory --- mod07_tty --- mod08_mib --- mod09_vm --- mod10_pfs --- mod11_mfs --- mod12_init
You can test the TFTP root directory with QEMU without setting up a DHCP/TFTP server first. To boot with QEMU,
cd to the TFTP root directory and use the following command :
qemu-system-i386 --enable-kvm -m 1G -tftp . -bootp pxelinux.0 -boot n
