Last updated on FEBRUARY 15, 2018

Applies to:

Sun Fire V440 Server - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.


An XVR-100 Card installed in PCI#2 no longer outputs to external display after updating from OBP 4.16.1 to 4.30.4.a with Patch 142707-01.

Server configuration and part numbers:

XVR-100 Frame Buffer card: 375-3181 pci slot 2
Ultra3 SCSI HBA: 375-3057 pci slot 4
motherboard 540-633
obp 4.16.1

375-3057 [F] PCI Dual Ultra3 SCSI Host Adapter (LVD)
QLogic QLA10162/66-SUN
3.3/5V 32/64Bit 33/66MHz


1.  When the server starts and probes devices, it detects the keyboard, then gives the message:

screen not found

2.  With a laptop connected to ALOM:

When the server boots, keyboard does nothing.  After the obp settings are applied, the keyboard connected to the server inputs to the laptop connected to the ALOM.  

3.  From the OBP, after motherboard replacement:

{0} ok cd /pci@1c,600000
{0} ok ls
f00eeec4 network@2
f00e1930 NOT NAMED <<<<<where the XVR frame buffer entry should be

4.  show-displays outputs nothing

      {1} ok show-displays
      {1} ok (No output here)

5.  show-devs indicates the card is found during the probe

      {0} ok show-devs
      @ /pci@0/pci@0/pci@9/SUNW,XVR-100@2   [NOTE: I have not cd'd into the device tree to check .properties yet]

6.  prtdiag -v shows the card too


7.  fbconfig -list shows:

      /dev/fbs/pfb0        Not Configurable
      /dev/fbs/pfb0a        Not Configurable
      /dev/fbs/pfb0b        Not Configurable
      /dev/fbs/pfb1        Not Configurable
      /dev/fbs/pfb1a        Not Configurable
      /dev/fbs/pfb1b        Not Configurable


8.  Checking the device link:

      /dev/fb -> pci@1d,700000/SUNW,XVR-100@2:pfb1
