+<li><b>ReiserFS</b>—This driver originated with rEFIt. It's useful
+ for reading Linux kernels from a separate <tt>/boot</tt> partition, or
+ even from a root (<tt>/</tt>) filesystem, if you use ReiserFS on it.
+ <b>Caution:</b> If you use this driver, you should use the
+ <tt>notail</tt> option in Linux's <tt>/etc/fstab</tt> file for the
+ partition(s) you want the EFI to read. This is because the driver
+ doesn't properly handle ReiserFS's "tail-packing" feature, so files can
+ seem to be corrupted in EFI if you use this feature, which is disabled
+ by <tt>notail</tt>.</li>
+
+<li><b>Ext2fs</b>—This driver also originated with rEFIt. It can be
+ used in the same way as the ReiserFS driver. Although it's called an
+ "ext2fs" driver, it also works with ext3fs.</li>
+
+<li><b>Ext4fs</b>—Stefan Agner <a
+ href="https://github.com/falstaff84/rEFInd">modified the rEFIt/rEFInd
+ ext2fs driver</a> so that it could handle ext4fs. I'm including this as
+ a separate driver from the ext2fs driver, although the ext4fs version
+ can handle ext2fs and ext3fs, too. (I may eventually retire the
+ original ext2fs driver, but I want to be conservative about this in
+ case there's an undiscovered problem with the new driver.) This driver
+ has some limitations. Most notably, for various reasons it maxes out at
+ 16TiB and won't mount any ext4 filesystem that's larger than this. As
+ of version 0.6.1, this driver supports the <tt>meta_bg</tt> feature,
+ which can also be used on ext2fs and ext3fs. Thus, it can handle some
+ ext2fs and ext3fs partitions that the ext2fs driver can't handle. You
+ can learn about your ext2/3/4 filesystem features by typing <tt
+ class="userinput">dumpe2fs <i>/dev/sda2</i> | grep features</tt>,
+ changing <tt class="userinput"><i>/dev/sda2</i></tt> to your
+ filesystem's device.</li>
+
+<li><b>ISO-9660</b>—This driver originated with rEFIt's author, but
+ he never released a final version. Its code was improved by Oracle for
+ use in its VirtualBox product, and then further modified by the authors
+ of the <a
+ href="https://sourceforge.net/projects/cloverefiboot/">Clover</a> boot
+ loader. If your firmware doesn't provide its own ISO-9660 driver, this
+ one can be helpful; however, you may need to install it on your hard
+ disk before you can read an optical disc.</li>
+
+<li><b>HFS+</b>—Oracle seems to have written this driver, apparently
+ with some code taken from open source Apple examples. It was then
+ further modified by the Clover authors. I expect this driver to have
+ limited appeal to most rEFInd users. Macs don't need it, since Apple's EFI
+ implementation provides its own HFS+ driver, and HFS+ isn't normally
+ used on UEFI-based PCs. Some CDs are mastered with both ISO-9660 and
+ HFS+, or even with HFS+ alone, and it's conceivable that an HFS+ driver
+ would be useful when accessing such discs. I'm providing the driver
+ mainly because it compiled cleanly with no extra work, aside from
+ providing a Makefile entry for it.</li>
