Using the Default Monitor Mode
DOME configures Md4/PCX boards with a default moni-
tor mode before shipment. When you use an Md4/PCX
board as the boot console, you must connect the board to a
monitor capable of displaying this default monitor mode.
See "Changing the Console" on page 108 for information
about making the Md4/PCX board the console.
The display resolution of the default monitor mode for the
Md4/PCX board is 1280 x 1024 pixels @ 76 Hz.
If you are using a Sun display board as the boot console,
you can use it to check the default mode programmed on
your Md4/PCX board. You can also use the Sun console to
change the default monitor mode on the Md4/PCX board.
Resolutions above 1600 x 1200 pixels require a fansink
on the DAC on the Md4/PCX board. If your board uses
a passive heatsink, the display resolution is limited to
1600 x 1200 pixels or lower.
To check the default mode
After you install the driver software package and reboot
your computer (if necessary), you can use the
program to check and change the default monitor mode.
