'Known good', means that it works on another Sun[TM] system and is listed on Sun's HCL (if not a Sun manufactured device) :http://www.sun.com/bigadmin/hcl/data/sol/)

The device path for the onboard graphics port (ATi Rage XL) will look similar to:

# ls -la /dev/fb*
lrwxrwxrwx   1 root     root          46 Jan 16 17:10 /dev/fb -> /devices/pci@0,0/pci10de,5c@9/display@5:text-0

lrwxrwxrwx   1 root     root          10 Jan 12 17:09 /dev/fb0 -> fbs/text-0

/dev/fbs:
total 12
drwxr-xr-x   2 root     root         512 Jan 12 17:09 .
drwxr-xr-x  16 root     sys         3584 Jan 16 17:10 ..
lrwxrwxrwx   1 root     root          51 Jan 12 17:09 text-0
-> ../../devices/pci@0,0/pci10de,5c@9/display@5:text-0

The device pointing to 'text-0'  could be seen as an invalid link but this is correct.

The first to take is to ensure the 'bootenv.rc' file contains the correct entries for the input and output device.  This is achieved via the 'eeprom' command in Solaris[TM]:

# man eeprom

<--start extract-->

x86
EEPROM storage is simulated using a  file  residing  in  the
platform-specific   boot   area.   The   /platform/platform-
name/boot/solaris/bootenv.rc file simulates EEPROM storage.

<--end extract-->

Complete as follows:

# eeprom input-device=keyboard
# eeprom output-device=screen

Check the settings with the 'eeprom' command with no options.

Try rebooting, assuming that 'Xsun' or 'Xorg' (display managers) are configured correctly (only use one or the other).

If you get display output all the way through boot, dtlogin should then appear.

If the display still goes blank early in boot the process, check the '/var/dt/Xerrors' file for errors (and the '/var/log/Xorg.0.log' if running Xorg).

An example of the errors you could see in Xerrors is:

In the above example you can see the 'Xorg' configuration is incorrect as the Xserver is unable to find the keyboard device (required to start the Xserver).

To correct this or any misconfiguration of the display managers,  you will need to run 'kdmconfig', select your display manager (Xsun or Xorg) and following the on-screen instructions.

To choose which driver you need for the display device you can run 'prtpicl -v' to get the make and model of the graphics card/port(s) e.g:

:video-adapter-type   svga
:vesa-oem-vendor     ATI Technologies Inc
:vesa-oem-string     ATI MACH64
:vesa-oem-revision   01.00
:vesa-oem-product    MACH64GM

You may also need to run 'devfsadm' first to ensure t newly attached keyboard and mouse are correctly linked

Once the Xserver via 'kdmconfig'  has been configured, test the configuration via the same command by selecting to continue through the fist couple of screen and then when displayed select 'F2' to test the current configuration. If a screen with multicoloured bubbles is displayed, the configuration is correct and after a reboot all output should be sent to the locally attached monitor
