Notes

1. The minimum OS is Solaris 1.1.2 or Solaris 2.4 Hardware: 11/94.
2. The PLCC Boot PROM is not a FRU and is not field replaceable.
3. Serial Port B supports asynchronous operation only.
4. Sync on green produces a higher than normal green output level when the tcx frame buffer is connected to the 16-inch Sony Mid-Range and 17-inch Nokia Entry-Level Color Monitors. Refer to BugID 14902389 [SUNBT1218690].
5. OBP settings for the SS4 tcx framebuffer use the Pixel frequency instead of the Vertical frequency.
6. 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
