* One of the following:
* The TianoCore EDK2 package
- (http://sourceforge.net/projects/tianocore/). I've tested using the
- UDK2010.SR1 and UDK2010.SR1.UP1 variants
- (http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=UDK2010),
- which are "frozen," rather than the main EDK2 development branch, which
- is changing as the developers add features, fix bugs, and so on. Using
- TianoCore EDK2 is supported in rEFInd version 0.4.3 and later (0.4.0
- and later for the filesystem drivers only). See below for TianoCore
- setup instructions.
+ (http://sourceforge.net/projects/tianocore/). I initially used the
+ UDK2010 package and others in that series, but beginning with rEFInd

* The GNU-EFI package (http://sourceforge.net/projects/gnu-efi/). You can
install this from a package called "gnu-efi"; however, rEFInd relies on
- features that were added in (I think) 3.0l to provide driver-loading
- capabilities. The versions I've used and that work are 3.0p, 3.0q,
- 3.0r, 3.0s, and 3.0u, with a caveat: The new time-sensitive
- default_selection feature causes rEFInd to hang when using 3.0s and
- earlier. 3.0u works fine for this (tested with compilation on three
- computers). I don't know if 3.0t would work. Through mid-to-late 2012,
- most Linux distributions delivered rather elderly versions of GNU-EFI,
- but many are catching up by late 2012. You should check your GNU-EFI
- version number; you may need to download the latest source code,
- compile it, and install it locally. Between rEFInd version 0.2.7 and
- 0.6.1, the Makefiles assumed a locally-compiled GNU-EFI package, but
- older and more recent versions assume GNU-EFI installation in typical
- locations for distribution-provided packages. The legacy BIOS boot
- support on UEFI-based PCs doesn't work when rEFInd is compiled under
- GNU-EFI, so as of rEFInd 0.4.6, GNU-EFI is no longer the primary build
- environment, although it's easier to set up on a Linux system.

+ recommend using 3.0u (or conceivably later). You should check your

+ GNU-EFI package installed via a package manager. If you install from

Of the two toolkits, I prefer to use TianoCore because it produces binaries

had problems on a 32-bit Mac Mini with the drivers produced by GNU-EFI
hanging the system if I try to load more than one of them. (I haven't
encountered this problem on UEFI-based PCs.) That said, the TianoCore EDK2

It's possible to use a non-Linux platform to compile rEFInd. To the best of
my knowledge, the rEFInd code doesn't rely on anything Linux-specific in
Preparing Your Development Kit
==============================
-If you don't care about booting BIOS-based OSes on UEFI PCs and if you're
-using Linux, GNU-EFI is the easiest way to compile rEFInd. I don't describe
-GNU-EFI's setup here because it's likely to be fairly easy. If your
-distribution provides a recent enough version, you should be able to
-install a package called gnu-efi and be done with it. If not, you'll need
-to download the source code tarball, build it, and install it. This process
-is fairly typical of Linux packages. Read the GNU-EFI documentation if you
-need help. If you're using GNU-EFI, you can skip the rest of this section.

Unfortunately, the TianoCore toolkit is weird by Linux programming
standards. It's also quite large -- it's intended as a means to develop a
complete EFI firmware implementation, so it contains much more code than is
procedure. The installation documentation also omits at least one step and
is a bit unclear about others. Here's how I installed the toolkit:
-1) Download UDK2010.SR1.UP1.P1 from

+1) Download UDK2014.SR1.UP1.P1 from

Makefile for rEFInd's EFI drivers assumes this location. You'll need to
edit the EDK2BASE line in the Make.tiano file if you install somewhere
else.
-3) Type "cd /usr/local/UDK2010".
+3) Type "cd /usr/local/UDK2014".

If you installed in a location other than the one I've specified, you must
edit the EDK2BASE variable in the Make.tiano and filesystems/Make.tiano
default Make.common file includes the following definitions:
EFIINC = /usr/include/efi

-EFICRT0 = /usr/lib64
+GNUEFILIB = /usr/lib
+EFILIB = /usr/lib
+EFICRT0 = /usr/lib
If you've installed GNU-EFI from source code, you may need to add "local"
to those paths, as in "/usr/local/include/efi". You might need to change
-references to "lib64" to "lib32" or "lib" on some systems. Recall that you
+references to "lib" to "lib32" or "lib64" on some systems. Recall that you
need at least GNU-EFI version 3.0l to build rEFInd, and until very
recently, most distributions provided out-of-date versions of this package.
Oracle's VirtualBox project (https://www.virtualbox.org) and the Clover
boot loader project (https://sourceforge.net/projects/cloverefiboot/),

+Adding Support for Network Boot
+===============================
+
+rEFInd provides EXPERIMENTAL support for booting over the network using
+iPXE (http://ipxe.org) as a means to receive the payload. In order to
+enable this feature you'll want to follow these instructions:
+
+* cd net/
+* make source
+* make netboot
+* copy bin/ipxe.efi and bin/ipxe_discover.efi to the EFI volume at EFI/tools/
+
+Note that you may need to install additional development packages, such as
+libiberty-dev and binutils-dev, in addition to those needed to build rEFInd
+itself.
+
+My own tests show this support to work under optimal conditions; however,
+architecture (EFI vs. BIOS) detection may not work, and some computers will
+hang or won't retrieve boot files from the network. For these reasons, this
+support is disabled by default in rEFInd, and I do not provide iPXE
+binaries.
