|

><P
|
|
>During make config, you need to choose whether to
|
|
compile promcon and / or
|
|
fbcon. You can select both, but if
|
|
you do this, you will need to set the kernel
|
|
flags to select the device. fbcon
|
|
always takes precedence if not set. If
|
|
promcon is not selected in, on
|
|
boot up, it defaults to dummycon.
|
|
If promcon is selected, it will
|
|
use this device. Once the buses are booted, and
|
|
fbcon is compiled in, the kernel
|
|
probes for the above framebuffers and will use
|
|
fbcon. If there is no framebuffer
|
|
devices, it will default to
|
|
promcon</P

gives you a nice fast text console with a text

resolution of 96x40, looks similar to a Solaris

console but with colours and virtual terminals
|

just like on the x86 platform.</P

>If you want to use the SUN12x22

|
font, you need to enable it during make config

(disable the fontwidth != 8
|
|
option). The accelerated framebuffers can
|
|
support any font width between one to sixteen
|
|
pixels, whilst dumb frame buffers only supports

|
4, 8, 12 and 16 pixel font widths.</P
