SCSI hard drive not recognized, or fails to boot - IBM IntelliStation Z Pro (Type 6899)

Troubleshooting


Problem

IBM IntelliStation Z Pro (Type 6899) systems may not recognize a SCSI device when attached to an IBM 16 Bit AT Fast SCSI PCI PnP adapter if there are no devices attached to the system board IDE controller.

Resolving The Problem

IBM IntelliStation Z Pro (Type 6899) systems may not recognize a SCSI device when attached to an IBM 16 Bit AT Fast SCSI PCI PnP adapter if there are no devices attached to the system board IDE controller.

For example, if the boot device (C:) is a SCSI drive attached to the IBM 16 Bit AT Fast SCSI PCI PnP adapter, and an IDE CDROM drive is attached to the system board IDE controller, removing the cable from the IDE CDROM drive will cause the system not to recognize the SCSI boot drive.

This problem does not occur with the Adaptec 2940-UW SCSI adapter.

Customers requiring use of the IBM 16 Bit AT Fast SCSI PCI PnP adapter should be made aware that the use of this adapter requires an IDE device to be installed on the system board IDE controller.
