 +===== Tiny Core Linux over HTTP =====
 +This application note describes how [[http://​tinycorelinux.com/​|Tiny Core Linux]] can be HTTP-booted using the gPXE network bootloader.
 +==== Overview ====
 +Although Tiny Core Linux comes with PXE netboot support, HTTP booting is attractive because it is more flexible. ​ Only a HTTP server is required (rather than a full DHCP + TFTP setup). ​ HTTP also works well over the internet.
 +Tiny Core Linux is "the core needed to boot into a very minimal X desktop typically with wired internet access"​. ​ From there you can load applications on-demand from the internet. ​ It's a great starting point for a custom thin-client or for one-off Linux sessions without big downloads upfront.
 +==== Preparing to HTTP boot ====
 +Download the latest Tiny Core Linux ISO image:
 +  wget http://​distro.ibiblio.org/​pub/​linux/​distributions/​tinycorelinux/​release/​tinycore_1.2.iso
 +Mount the ISO:
 +  mount -o loop tinycore_1.2.iso /mnt
 +Copy kernel and initramfs to a web-accessible directory:
 +  cp /​mnt/​boot/​{bzImage,​tinycore.gz} /var/www
 +Create a gPXE script for easy booting:
 +  cat >/​var/​www/​tinycore.gpxe
 +  #!gpxe
 +  kernel http://​example.org/​bzImage
 +  initrd http://​example.org/​tinycore.gz
 +  boot
 +  ^D
 +==== Booting a client machine ====
 +Boot gPXE and enter the following command at the shell (Ctrl+B):
 +  dhcp net0
 +  chain http://​example.org/​tinycore.gpxe
 +Tiny Core Linux should download via HTTP and boot.
 +==== Going further... ====
 +You may want to add kernel command-line arguments like this in ''​tinycore.gpxe'':​
 +  kernel http://​example.org/​bzImage lang=en kmap=us
