Booting from DHCP and TFTP
If you want to utilize netboot.xyz from your home or office network, it's relatively easy to set up. It will allow all of your devices on your network to have netboot.xyz available whenever you need it by just changing the boot order on your device, selecting network boot, or manually selecting the device to boot.
DHCP Server Setup
You will have to tell your DHCP server to provide a "next-server", the address of a TFTP server on your network, and a "filename", the netboot.xyz boot file. When your clients boot up, if they are set to network boot, they'll automatically get a valid DHCP address, pull down the netboot.xyz iPXE bootloader and load up the Operating System menu.
next-server "126.96.36.199" filename "netboot.xyz.kpxe"
TFTP Server Setup
You will need to set up a tftp server to host the iPXE files. There are various types of TFTP servers out there and they all usually work pretty well. You can also use dnsmasq to host the files as well.
If you use dnsmasq you can add this configuration to /etc/dnsmasq.conf:
enable-tftp tftp-root=/var/lib/tftp dhcp-boot=netboot.xyz.kpxe
Regular and Undionly Boot Files
If you experiencing issues with the regular netboot.xyz.kpxe bootloader, you can try and use the netboot.xyz-undionly.kpxe bootloader. The regular bootloader includes common NIC drivers in the iPXE image, while the undionly loader will piggyback off the NIC boot firmware.
