-The first step here is to compile and install this hack which allows
-us to use arrow keys (yes, arrow keys) to navigate the F11 boot menu:
+ 1. From the iDRAC home page, click Launch under Virtual Console
+    Preview
+
+ 2. In the console window menu, click Virtual Media then Launch
+    Virtual Media
+
+ 3. Click Add Image and select an .ISO or .IMG file
+
+ 4. Click the checkbox under Mapped for the new image file
+
+ 5. Leaving that window open, bring the console back into focus
+
+ 6. (Re)boot the machine, pressing F11 to bring up the boot menu
+
+ 7. Choose Virtual CD if you mapped an .ISO image, or Virtual Floppy
+    in the case of a 1.44MB floppy image
+
+Now, it's possible that an annoying bug will manifest itself at this
+stage: because the Java applet was conceived to work with an old X11
+version, the keycodes for the arrow keys may not work. Without these
+keys, choosing an alternative boot option cannot be done.
+
+To fix this we can use a custom library designed to fix this exact
+problem with iDRAC web console:
