Subject: Added documentation for new enable_touch support. Also tweaked inclusion
X-Git-Url: https://code.delx.au/refind/commitdiff_plain/433d93ad78d6b1947938be72f248e03833943847?hp=dd910ca40c3ea630983ad18cf1a23e0afe38ffe9

Added documentation for new enable_touch support. Also tweaked inclusion
condition for EfiLib/AbsolutePointer.h, since the latest GNU-EFI seems
to include equivalent definitions.

 -------------------
 
+- An anonymous contributor has provided support for touch screens. This
+  support requires that the "enable_touch" token be used in refind.conf.
+  Note, however, that not all tablet computers have EFIs that provide the
+  necessary support in the firmware.
+
+- Martin Whitaker contributed 64-bit support to the ext4fs driver, which
+  makes it compatible with ext4fs as written by some recent Linux
+  distributions.
+
 - Tweaked refind-install to do a better job of detecting disks other
   than /dev/sd? and /dev/hd? devices.

If you set a resolution that doesn't work on a UEFI-based system, rEFInd displays a message along with a list of valid modes. On an system built around EFI 1.<i>x</i> (such as a Mac), setting an incorrect resolution fails silently; you'll get the system's default resolution. You'll also get the system's default resolution if you set both resolution values to <tt>0</tt> or if you pass anything but two numbers. (Note that passing a resolution with an <tt>x</tt>, as in <tt>1024x768</tt>, will be interpreted as <i>one</i> option and so will cause the default resolution to be used.) If you get a higher resolution than you request, try commenting out or changing the <tt>textmode</tt> value, since it can force the system to use a higher graphics resolution than you specify with <tt>resolution</tt>. Also, be aware that it is possible to set a valid resolution for your video card that's invalid for your monitor. If you do this, your monitor will go blank until you've booted an OS that resets the video mode.</td>
