6. Reset the OpenBoot PROM:
The system now uses the Sun XVR-100 graphics accelerator as the new console

11.5.4.5 Avoiding Colormap Flash
Your Sun Blade 1500 workstation might ship with a Sun XVR-100 graphics
accelerator configured to 8-bit color depth.
If you experience colormap flashing (incorrect colors or color changes), your
graphics accelerator might be incorrectly configured. Perform one of the following
procedures to set 24-bit or 8+24-bit color depth.
Setting 24-bit Color Depth
1. Using the fbconfig command, set the Sun XVR-100 to 24-bit color depth.
2. Log out, then log back in for the change to take effect.
Note – 24-bit color depth performance might be slower than 8-bit color depth
performance.
Setting 8+24-bit Color Depth
Note – Do not invoke 8+24-bit color depth when two monitors are connected to one
XVR-100 graphics accelerator.
