-	  The STI console is the builtin display/keyboard on HP-PARISC
-	  machines.  Say Y here to build support for it into your kernel.
+	  STI refers to the HP "Standard Text Interface" which is a set of
+	  BIOS routines contained in a ROM chip in HP PA-RISC based machines.
+	  Enabling this option will give you an 8 color text console on
+	  most of the PA-RISC systems.
+	  Really old HP boxes may not have STI, in which case you must use the
+	  PDC console or your primary serial port as a console.
+	
+	  The text console uses a strange memory layout, and changing the 
+	  plane mask to create colored characters requires calls to the STI 
+	  routines. Because of that do not expect it to be actually very fast,
+	  but it is sufficient for basic text console functions, including fonts.
+	
 	  The alternative is to use your primary serial port as a console.
+	
+	  It is safe to enable this option, so you should probably say "Y".
