help
If you have a LCD controlled by one or more KS0108

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)

To compile this as a module, choose M here:
the module will be called ks0108.

help
The address of the parallel port where the LCD is connected.
The first standard parallel port address is 0x378.
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.
If you compile this as a module, you can still override this
using the module parameters.

The LCD framebuffer driver can be attached to a console.
It will work fine. However, you can't attach it to the fbdev driver

config CFAG12864B_RATE
int "Refresh rate (hertz)"
depends on CFAG12864B
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.
If you don't know what I'm talking about, ignore it.
If you compile this as a module, you can still override this
value using the module parameters.
