 Success is defined as reaching the busybox shell prompt.
+=== Detailed test procedure ===
+== Prerequisites ==
+  * x86 uClibc toolchain (configured with RPC and large-file support)
+  * wrapper script for uClibc compiler named ''uclibc''
+  * git
+  * x86 Linux kernel (TODO: this should be built from source as well)
+  * HTTP and DHCP servers
+== Source checkout ==
+  git clone git://git.etherboot.org/scm/people/mcb30/mkbootfs.git
+  cd mkbootfs
+  git-submodule init
+  git-submodule update
+== mkbootfs build ==
+In the ''mkbootfs'' directory, ensuring the ''uclibc'' wrapper is in the $PATH, simply ''make''.
+== Server configuration ==
+Copy all .bp files from the mkbootfs directory to the HTTP server.
+Copy the x86 Linux kernel bzImage to the HTTP server.
+Write a gPXE script on the HTTP server to boot Linux with the .bp files as initrds:
+  #!gpxe
+  kernel http://server/dir/bzImage
+  initrd http://server/dir/skeleton.bp
+  initrd http://server/dir/busybox.bp
+  initrd http://server/dir/policy.bp
+  initrd http://server/dir/iscsi.bp
+  boot
+Configure the DHCP server to instruct the device under test to boot from this gPXE script:
+  filename "http://server/dir/script.gpxe";
+== Boot ==
+Start the test machine; it should boot to a busybox shell prompt with a "gPXE Universal Boot" banner.
