Notes
- The minimum operating system is X Terminal Software Version 2.1.
- The PLCC Boot PROM is not a FRU and is not field replaceable.
- The serial ports are not supported.
- OBP settings for the tcx framebuffer use the Pixel frequency instead
of the Vertical frequency.
- Use the OBP setenv command to change the frame buffer resolution:
- ok setenv fcode-debug? true
- ok reset
- ok setenv output-device screen:r1152x900x94
- ok setenv output-device screen:r1024x768x84
