+Most tools you want to boot are probably Linux systems. To boot them, you need
+a *kernel* and some (initial) filesystem. One way is to load an *initrd*
+(initial ramdisk) which contains only the basic stuff and mounts the big
+filesystem itself. Or you can mount the "big" filesystem directly and use that
+from the beginning.
+
+You can find my current config [here](https://github.com/mbirth/ipxe-config).
+And below you'll find detailed instructions for those tools.

+
+
+Bootstrap
+=========
+
+For general preparation, I fill some variables with architecture relevant data,
+e.g. if the system is 32bit or 64bit. And to spice things up, I also have a few
+variables with colour codes. This is the code I use:
+
+```
+set esc:hex 1b
+set bold ${esc:string}[1m
+set orange ${esc:string}[33;0m
+set yellow ${esc:string}[33;1m
+set cyan ${esc:string}[36;1m
+set resetfg ${esc:string}[39m
+set resetbg ${esc:string}[49m
+set resetbold ${esc:string}[22m
+set reset ${esc:string}[0m
+
+# Figure out if client is 64-bit capable
+cpuid --ext 29 && set arch x86_64 || set arch x86
+cpuid --ext 29 && set archb 64 || set archb 32
+cpuid --ext 29 && set archl x86_64 || set archl i386
+
+set chotkey ${bold}
+set cname ${orange}
+```
+
+
+AVG Rescue CD
+=============
+
+* [AVG Rescue CD](http://www.avg.com/ww-en/avg-rescue-cd)
+
+```
+echo Booting ${cname}AVG Rescue CD${reset}
+set base-url ${boot-url}avg/
+kernel ${base-url}vmlinuz max_loop=255 init=linuxrc vga=ask reboot=bios
+initrd ${base-url}initrd.lzm
+boot || goto failed
+```
+
+
+BitDefender Rescue CD
+=====================
+
+* [BitDefender Rescue CD](http://www.bitdefender.com/support/how-to-create-a-bitdefender-rescue-cd-627.html)
+
+```
+echo Booting ${cname}BitDefender Rescue CD${reset} (${archl})
+set base-url ${boot-url}bitdefender/
+kernel ${base-url}kernel.${archl} root=/dev/nfs real_root=/dev/nfs nfsroot=172.16.254.1:/volume1/web/ipxe/bitdefender/cd/ ip=${ip} loop=/rescue/livecd.squashfs looptype=squashfs livecd.nfsif=${mac} initrd udev cdroot nosplash lang=en
+initrd ${base-url}initfs.${archl}
+boot || goto failed
+```
+
+
+CloneZilla
+==========
+
+* [CloneZilla](http://clonezilla.org/)
+
+```
+echo Booting ${cname}Clonezilla${reset} (${arch})
+set base-url ${boot-url}clonezilla/${arch}/
+kernel ${base-url}vmlinuz boot=live union=overlay username=user config components noswap edd=on nomodeset nodmraid noeject locales= keyboard-layouts= ocs_live_run="ocs-live-general" ocs_live_extra_param="" ocs_live_batch=no vga=normal net.ifnames=0 nosplash i915.blacklist=yes radeonhd.blacklist=yes nouveau.blacklist=yes vmwgfx.enable_fbdev=1 fetch=${base-url}filesystem.squashfs
+initrd ${base-url}initrd.img
+boot || goto failed
+```
+
+
+DFSee
+=====
+
+For [DFSee](http://www.dfsee.com/) the easiest way is to load the whole ISO
+image into RAM and boot it from there.
+
+```
+echo Booting ${cname}DFSee${reset}
+kernel ${boot-url}memdisk iso raw
+initrd ${boot-url}dfsee/dfsee.iso
+boot || goto failed
+#sanboot --no-describe --drive 0x00 ${sanboot-url}dfsee/dfsee.iso
+```
+
+(The `sanboot` line didn't work for me for some reason. That's why I used
+[memdisk](http://www.syslinux.org/wiki/index.php?title=MEMDISK) instead.)
+
+
+FSecure
+=======
+
+Getting the [F-Secure Rescue CD](https://www.f-secure.com/en/web/labs_global/rescue-cd)
+to boot via the network is a bit more complicated (if you want to avoid using
+`memdisk`).
+
+From the ISO image, you need the following:
+
+* `boot/isolinux/fsecure/linux` --- kernel
+* `boot/isolinux/fsecure/minirt.gz` --- init ramdisk
+* `KNOPPIX/` --- folder with the remaining system files
+
+Then proceed according to [this](http://www.syslinux.org/wiki/index.php?title=WDSLINUX#F-Secure_Antivirus_Rescue_CD):
+
+* Copy the extracted `minirt.gz` file and `KNOPPIX/` folder to a temporary
+  location on a linux machine (e.g. `/root/tmp`)
+* In the `/root/tmp` location create a folder called `fsecure` and change
+  into this directory
+
+    mkdir /root/tmp/fsecure
+    cd /root/tmp/fsecure
+
+* Type the following command and press enter (this extracts all the files from
+  the `minirt.gz` file)
+
+    gunzip -c ../minirt.gz | cpio -idv
+
+* Copy the `KNOPPIX` folder to the `mnt-system` folder (from the now extracted
+  `minirt.gz`)
+
+    cp -r ../KNOPPIX mnt-system
+
+* Make a backup copy of the `init` file
+
+    cp init init.orig
+
+* Edit the `init` file with the following modifications
+
+  * Find the `# findknoppix devices...` section and delete everything from the
+    `findknoppix()` method and replace it by `return 0`
+
+Change
+
+```
+# findknoppix devices...
+findknoppix(){
+ local dev
+ for dev in "$@"; do
+  [ -b "$dev" ] || continue
+  echo -n -e "\r${CRE}${BLUE}${SEARCHINGFOR} $DISTRO in: ${MAGENTA}$dev${NORMAL}   "
+  trymount "$dev" /mnt-system >/dev/null 2>&1 || continue
+  if [ -r /mnt-system/"$knoppix_dir"/KNOPPIX ] ; then
+      # We must have also fsecure structure present else we might try to mount something wrong.
+      if [ -d /mnt-system/fsecure/rescuecd ] || [ -d /mnt-system/boot/isolinux/fsecure ] ; then
+         echo -e "\r${CRE}${GREEN}$DISTRO ${FOUNDAT}: ${MAGENTA}$dev${NORMAL}       "
+         return 0
+      fi
+  fi
+  umount /mnt-system
+ done
+ return 1
+}
+```
+
+into
+
+```
+# findknoppix devices...
+findknoppix(){
+ return 0
+}
+```
+
+* Compress everything back into a file again by typing the following and
+  press enter
+
+    find . -print | cpio -o -H newc |gzip -9 -c - > ../minirt.gz.new
+
+* Copy the new `minirt.gz.new` to the `fsecure` directory on the web server
+  and name it `minirt.gz`
+
+* Copy the `linux` kernel to the same directory
+
+This is the iPXE boot code:
+
+```
+echo Booting ${cname}F-Secure Rescue CD${reset}
+set base-url ${boot-url}fsecure/
+kernel ${base-url}linux ramdisk_size=100000 lang=en vt.default_utf8=0 apm=power-off vga=normal nomce loglevel=1 nolapic_timer nosound console=tty10 video=noblank
+initrd ${base-url}minirt.gz
+boot || goto failed
+```
+
+
+G4L - Ghost for Linux
+=====================
+
+* [G4L - Ghost for Linux](https://sourceforge.net/projects/g4l/)
+
+```
+echo Booting ${cname}G4L - Ghost for Linux${reset}
+set base-url ${boot-url}g4l/
+kernel ${base-url}bz4x2.8
+initrd ${base-url}ramdisk.lzma
+boot || goto failed
+```
+
+
+g4u - ghost for unix
+====================
+
+* [g4u - ghost for unix](http://www.feyrer.de/g4u/)
+
+```
+echo Booting ${cname}g4u - ghosting for unix${reset}
+set base-url ${boot-url}g4u/
+#kernel ${base-url}netbsd
+#initrd ${base-url}miniroot.kmod
+kernel ${boot-url}memdisk iso raw
+initrd ${base-url}g4u-2.5.iso
+boot || goto failed
+```
+
+
+GParted Live
+============
+
+* [GParted Live](http://gparted.org/livecd.php)
+
+```
+echo Booting ${cname}GParted Live${reset} (${arch})
+set base-url ${boot-url}gparted/${arch}/
+kernel ${base-url}vmlinuz boot=live union=overlay username=user config components noswap noeject ip= net.ifnames=0 nosplash fetch=${base-url}f
+ilesystem.squashfs
+initrd ${base-url}initrd.img
+boot || goto failed
+```
+
+
+HDT - Hardware Detection Tool
+=============================
+
+[HDT](http://www.hdt-project.org/) comes as a small floppy image and can be
+booted using the `sanboot` command.
+
+```
+echo Booting ${cname}Hardware Detection Tool${reset}
+sanboot --no-describe --drive 0x00 ${sanboot-url}hdt/hdt.img || goto failed
+```
+
+
+Memtest86 V6
+============
+
+[Memtest86](http://www.memtest86.com/) comes as a usb flash drive image which
+you can boot using [memdisk](http://www.syslinux.org/wiki/index.php?title=MEMDISK).
+
+```
+echo Booting ${cname}Memtest86 V6${reset}
+kernel ${boot-url}memdisk
+initrd ${boot-url}memtest86-6/memtest86-usb.img
+boot || goto failed
+#sanboot --no-describe --drive 0x00 ${sanboot-url}memtest86-6/memtest86-usb.img
+```
+
+(Again, `sanboot` didn't work for me.)
+
+
+Memtest86+ V5
+=============
+
+[Memtest86+](http://www.memtest.org/) is the free and open-source alternative
+to Memtest86. This is distributed as a ready-to-boot binary.
+
+```
+echo Booting ${cname}Memtest86+ V5${reset}
+boot ${boot-url}memtest86+/memtest86+.bin || goto failed
+```
+
+
+SystemRescueCD
+==============
+
+For the [SysRescCD](https://www.system-rescue-cd.org/), you need the
+following files from the ISO image:
+
+* `sysrcd.dat` --- "big" filesystem
+* `sysrcd.md5` --- checksum to validate the sysrcd.dat
+* `isolinux/rescue32` --- kernel for 32bit systems
+* `isolinux/rescue64` --- kernel for 64bit systems
+* `isolinux/initram.igz` --- initial ramdisk
+
+Copy those to a directory `sysresccd` on your web server (where the `boot.ipxe`
+is).
+
+SysRescCD looks for the "big" filesystem for itself. You just have to point it
+into the right direction with the `netboot` parameter.
+
+```
+echo Booting ${cname}SystemRescueCD${reset} (${archb})
+set base-url http://diskstation:80/ipxe/sysresccd/
+kernel ${base-url}isolinux/rescue${archb}
+initrd ${base-url}isolinux/initram.igz
+imgargs rescue${archb} setkmap=de dodhcp netboot=${base-url}sysrcd.dat
+boot || goto failed
+```
+
