There is the option to use the PROM to output characters to the display or to a serial console.
Also, have a look at the Sparc Frame Buffer FAQ at http://c3-a.snvl1.sfba.home.com/Framebuffer.html
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
Here are the kernel options
video=sbus:options
where options is a comma separated list:
nomargins
-
sets
margins
to
0,
0
margins=12x24
-
sets
margins
to
12,
24
(default
is
computed
from
resolution)
off
-
don't
probe
for
any
SBus
/
UPA
framebuffers
font=SUN12x22
-
use
a
specific
font
So for example, booting with
video=sbus:nomargins,font=SUN12x22
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.
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.
It is recommended that you grab a recent consoletools packages.
