<ul>
+ <li>When in Secure Boot mode, rEFInd can launch just one driver that's
+ signed with a shim key or MOK. The second and later drivers
+ generate "access denied" errors. <!-- I think this is because of
+ the fast-and-loose sample code I borrowed from shim, which re-uses
+ rEFInd's own image handle (the <tt>image_handle</tt> variable in
+ <tt>start_image()</tt>) for launching shim/MOK-signed binaries. The
+ result is that when the second driver is loaded, it can't register
+ itself with the firmware because the firmware believes it's already
+ been registered. The solution is likely to involve creating a child
+ image handle rather than re-using rEFInd's own image handle, but
+ this is likely to be tedious to do—see
+ <tt>/usr/local/UDK2010/MyWorkSpace/MdeModulePkg/Core/Dxe/Image/Image.c</tt>
+ for the reference UEFI implementation. --> </li>
+
+ <li>When launching ELILO in Secure Boot mode, ELILO can't find its
+ configuration file. It's possible that a similar problem exists for
+ other boot loaders, too.</li>
+
+ <li>When setting a resolution higher than about 800x600 (or maybe even
+ 640x480) in text mode, the text displayed by rEFInd, and on some
+ systems shells and other programs launched from rEFInd, is
+ restricted to an 80x24-character area in the top-left corner of the
+ screen.</li>
+
<li>The <a href="http://www.rodsbooks.com/gb-hybrid-efi/">Gigabyte
Hybrid EFI</a> has a bug that causes the allegedly case-insensitive
<tt>StriCmp()</tt> function to perform a case-sensitive comparison.
<ul>
+ <li>With the arrival of PCs preloaded with Windows 8 and with Secure
+ Boot enabled, some way to cope is in order. I'm thinking of adding
+ code to limit or prohibit booting of unsigned boot loaders if
+ rEFInd detects that Secure Boot is active, and link with the <a
+ href="http://mjg59.dreamwidth.org/18945.html">Shim</a>
+ pre-bootloader to help handle signing and authentication. I need to
+ research the technical details more, though.</li>
+
<li>EFI supports network boots. rEFInd doesn't, but it would be nice if
it would.</li>
href="http://www.rodsbooks.com/bios2uefi/">DUET</a>). Nonetheless,
I'd like to track down the cause and fix it.</li>
- <li>The driver installation procedure could be improved, perhaps by
- adding support for drivers to the <tt>install.sh</tt> script.</li>
-
<li>The HFS+ driver returns a volume label of "HFS+ volume", no matter
what the volume's real label is.</li>
