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.
