Notes

  1. The minimum operating system is X Terminal Software Version 2.1.
  2. The PLCC Boot PROM is not a FRU and is not field replaceable.
  3. The serial ports are not supported.
  4. OBP settings for the tcx framebuffer use the Pixel frequency instead of the Vertical frequency.
  5. 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
