x86 only: 3Com EtherLink 3C509B Does Not Generate Interrupts (4153488)

3Com EtherLink III 3C905B cards in a Compaq ProLiant 6500 can fail to generate interrupts. The card sends packets but does not receive them.

Workaround: There is no known workaround for this problem. However, because some slots appear to have this problem occur more frequently than other slots, moving the card to another PCI slot might help. Also, successive reboots of the system have succeeded in getting the card out of this state.

x86 only: iprb: dma Overrun While Receiving Frame (4156622)

Some PCI motherboards contain DMA chipsets that are unable to support 100-Mbps Fast Ethernet.

Workaround: See "100-Mbps Ethernet Performance" in the Solaris 7 (Intel Platform Edition) Device Configuration Guide for additional information and recommended solution.

x86 only: ncrs: Mismatch of Narrow and Wide SCSI Operations on Intel N440BX Motherboard (4165916)

If there are Wide Small Computer System Interface (SCSI) targets attached to the Symbios adapter but your boot device is not one of these targets, then the Solaris driver does not successfully negotiate Wide SCSI data transfer and the devices do not operate correctly.

Workaround: Set the adapter firmware to 8-bit/narrow mode using the Symbios BIOS Configuration Utility:

• Enter the Symbios Configuration Utility by typing CTRL-C when prompted on boot.

• From the Main Menu, select the adapter with wide targets attached.

• From the Utilities Menu, choose Device Selection. Select the device and set the Width (bits) to 8.

  The Solaris driver still renegotiates to the highest shared data-transfer mode, resulting in no performance loss.

x86 only: kdmconfig: JumpStart Installation Fails With pnp Monitor (4166376)

JumpStart installations configured to use a Plug-and-Play monitor cannot be properly installed. The monitor information on the installed system is incomplete.

Workaround: Configure the JumpsStart installation to use a comparable multi-frequency monitor.
