+	  The LCD is accessible through the /dev/lcd char device (10, 156).
+	  This code can either be compiled as a module, or linked into the

+	  driver for your LCD.
+
+	  Depends on Parallel Port support. If you say Y at
+	  parport, you will be able to compile this as a module (M)
+	  and built-in as well (Y).
+

+	  The second standard parallel port address is 0x278.
+	  The third  standard parallel port address is 0x3BC.
+
+	  You can specify a different address if you need.
+
+	  If you don't know what I'm talking about, load the parport module,
+	  and execute "dmesg" or "cat /proc/ioports". You can see there how
+	  many parallel ports are present and which address each one has.
+
+	  Usually you only need to use 0x378.
+

+
+	  For help about how to wire your LCD to the parallel port,

+
+	  Depends on the x86 arch and the framebuffer support.
+
+	  The LCD framebuffer driver can be attached to a console.
+	  It will work fine. However, you can't attach it to the fbdev driver
+	  of the xorg server.
+
+	  To compile this as a module, choose M here:

+	int "Refresh rate (hertz)"

+	default "20"
+	help
+	  Refresh rate of the LCD.
+
+	  As the LCD is not memory mapped, the driver has to make the work by
+	  software. This means you should be careful setting this value higher.
+	  If your CPUs are really slow or you feel the system is slowed down,
+	  decrease the value.
+
+	  Be careful modifying this value to a very high value:
+	  You can freeze the computer, or the LCD maybe can't draw as fast as you
+	  are requesting.
+

+	  This is a driver that lets you use the lcd2s 20x4 character display

+	  This is a driver for the character LCD found on the ARM Ltd.
+	  Versatile and RealView Platform Baseboards. It doesn't do
+	  very much more than display the text "ARM Linux" on the first
+	  line and the Linux version on the second line, but that's

+	help
+	  Say Y here if you have an HD44780 or KS-0074 LCD connected to your

+	  is accessible through the /dev/lcd char device (10, 156), and the
+	  keypad through /dev/keypad (10, 185). This code can either be
+	  compiled as a module, or linked into the kernel and started at boot.

+
+if PARPORT_PANEL
+
+config PANEL_PARPORT
+	int "Default parallel port number (0=LPT1)"
+	range 0 255
+	default "0"
+	help
+	  This is the index of the parallel port the panel is connected to. One
+	  driver instance only supports one parallel port, so if your keypad
+	  and LCD are connected to two separate ports, you have to start two
+	  modules with different arguments. Numbering starts with '0' for LPT1,
+	  and so on.
+
+config PANEL_PROFILE
+	int "Default panel profile (0-5, 0=custom)"
+	range 0 5
+	default "5"
+	help
+	  To ease configuration, the driver supports different configuration
+	  profiles for past and recent wirings. These profiles can also be
+	  used to define an approximative configuration, completed by a few
+	  other options. Here are the profiles :
+
+	    0 = custom (see further)
+	    1 = 2x16 parallel LCD, old keypad
+	    2 = 2x16 serial LCD (KS-0074), new keypad

+	    4 = 2x16 parallel LCD (Nexcom NSA1045) with Nexcom's keypad
+	    5 = 2x40 parallel LCD (old one), with old keypad
+
+	  Custom configurations allow you to define how your display is
+	  wired to the parallel port, and how it works. This is only intended
+	  for experts.

+	help
+	  This enables and configures a keypad connected to the parallel port.
+	  The keys will be read from character device 10,185. Valid values are :
+

+	    1 : old 6 keys keypad
+	    2 : new 6 keys keypad, as used on the server at www.ant-computing.com
+	    3 : Nexcom NSA1045's 4 keys keypad
+
+	  New profiles can be described in the driver source. The driver also

+	range 0 5
+	default 0
+	help
+	   This enables and configures an LCD connected to the parallel port.
+	   The driver includes an interpreter for escape codes starting with
+	   '\e[L' which are specific to the LCD, and a few ANSI codes. The
+	   driver will be registered as character device 10,156, usually
+	   under the name '/dev/lcd'. There are a total of 6 supported types :
+
+	     0 : do not enable the driver
+	     1 : custom configuration and wiring (see further)
+	     2 : 2x16 & 2x40 parallel LCD (old wiring)

+	     4 : 2x16 parallel LCD (Hantronix wiring)
+	     5 : 2x16 parallel LCD (Nexcom wiring)
+
+	   When type '1' is specified, other options will appear to configure
+	   more precise aspects (wiring, dimensions, protocol, ...). Please note
+	   that those values changed from the 2.4 driver for better consistency.

+	depends on PANEL_PROFILE="0" && PANEL_LCD="1"
+	int "Internal LCD line width (1-40, 40 by default)"
+	range 1 40
+	default 40
+	help
+	  Most LCDs use a standard controller which supports hardware lines of 40
+	  characters, although sometimes only 16, 20 or 24 of them are really wired
+	  to the terminal. This results in some non-visible but addressable characters,
+	  and is the case for most parallel LCDs. Other LCDs, and some serial ones,
+	  however, use the same line width internally as what is visible. The KS0074
+	  for example, uses 16 characters per line for 16 visible characters per line.
+
+	  This option lets you configure the value used by your LCD in 'custom' profile.
+	  If you don't know, put '40' here.
+
+config PANEL_LCD_HWIDTH
+	depends on PANEL_PROFILE="0" && PANEL_LCD="1"
+	int "Hardware LCD line width (1-64, 64 by default)"
+	range 1 64
+	default 64
+	help
+	  Most LCDs use a single address bit to differentiate line 0 and line 1. Since
+	  some of them need to be able to address 40 chars with the lower bits, they
+	  often use the immediately superior power of 2, which is 64, to address the
+	  next line.
+
+	  If you don't know what your LCD uses, in doubt let 16 here for a 2x16, and
+	  64 here for a 2x40.
+
+config PANEL_LCD_CHARSET
+	depends on PANEL_PROFILE="0" && PANEL_LCD="1"
+	int "LCD character set (0=normal, 1=KS0074)"
+	range 0 1
+	default 0
+	help
+	  Some controllers such as the KS0074 use a somewhat strange character set
+	  where many symbols are at unusual places. The driver knows how to map
+	  'standard' ASCII characters to the character sets used by these controllers.
+	  Valid values are :
+
+	     0 : normal (untranslated) character set
+	     1 : KS0074 character set
+
+	  If you don't know, use the normal one (0).
+
+config PANEL_LCD_PROTO
+	depends on PANEL_PROFILE="0" && PANEL_LCD="1"
+	int "LCD communication mode (0=parallel 8 bits, 1=serial)"
+	range 0 1
+	default 0
+	help
+	  This driver now supports any serial or parallel LCD wired to a parallel
+	  port. But before assigning signals, the driver needs to know if it will
+	  be driving a serial LCD or a parallel one. Serial LCDs only use 2 wires
+	  (SDA/SCL), while parallel ones use 2 or 3 wires for the control signals
+	  (E, RS, sometimes RW), and 4 or 8 for the data. Use 0 here for a 8 bits
+	  parallel LCD, and 1 for a serial LCD.
