Intel EK-KZPCM-UG manual Problems With Ultra Devices Using Ultra Protocol

KZPCM PCI–to–Dual Channel Ultra SCSI and 10/100MB Ethernet Host Adapter

4.Be certain that your system’s console supports the 53C875 (Alpha firmware upgrade CD 5.0).

4.3.2Disk Drive is Recognized as Seven Different Devices When Only One is Physically Connected to the SCSI Bus.

1.This error is usually caused by older SCSI devices incorrectly indicating to Windows NT that they support multiple LUNs; contact the device manufacturer for a possible firmware upgrade.

2.This error can also occur if a disk is at the same SCSI ID as the controller. If you have not changed the SCSI ID of the Host Adapter from default (7), make sure there is no other SCSI device at ID 7.

4.3.3 Problems With Ultra Devices Using Ultra Protocol

1.If the system is configured with a SCSI host adapter that supports Ultra SCSI, an Ultra device is on the SCSI bus, and Fast 20/Ultra support by the SYMC8XX.SYS driver is enabled, intermittent problems and possible system crashes can occur if the SCSI bus cable and terminators do not conform to the Fast 20/Ultra specification.

2.If the system is bootable, disable Fast 20/Ultra support using Control C BIOS accessible from your Alpha BIOS console.

3.If the system operates properly without Fast 20/Ultra enabled, it is highly likely that the SCSI bus cable and terminators are not configured correctly for Fast 20/Ultra.
