 	---help---
 	  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 implement the linux framebuffer device and
-	  an fbcon color text console using calls to the STI BIOS routines.
-	  The HP framebuffer device is usually planar, uses a strange memory
-	  layout, and changing the plane mask to create colored pixels
-	  requires a call to the STI routines, so do not expect /dev/fb to
-	  actually be useful.  However, it is the best we have as far as
-	  graphics on the HP chipsets due to lack of hardware level
-	  documentation for the various on-board HP chipsets used in these
-	  systems.  It is sufficient for basic text console functions,
-	  including fonts.
-
-	  You should probably enable this option, unless you are having
-	  trouble getting video when booting the kernel (make sure it isn't
-	  just that you are running the console on the serial port, though).
-	  Really old HP boxes may not have STI, and must use the PDC BIOS
-	  console or the IODC BIOS.
+	  Enabling this option will implement the linux framebuffer device
+	  using calls to the STI BIOS routines for initialisation.
+	
+	  If you enable this option, you will get a planar framebuffer device
+	  /dev/fb which will work on the most common HP graphic cards of the
+	  NGLE family, including the artist chips (in the 7xx and Bxxx series),
+	  HCRX, HCRX24, CRX, CRX24 and VisEG series.
+
+	  It is safe to enable this option, so you should probably say "Y".
