SCSI Bus Interface Definitions

The basic host adapter settings are the SCSISelect settings most likely to require modification:

Host Adapter SCSI ID

— Sets the host adapter's SCSI ID. The default setting is SCSI ID 7, which allows the host adapter to support narrow

SCSI devices in addition to wide SCSI devices. Dell recommends that you leave the host adapter set to SCSI ID 7.

SCSI Parity Checking

— Determines whether the host adapter verifies the accuracy of data transfer on the SCSI bus. The default setting is

Enabled. You should disable SCSI Parity Checking if any SCSI device connected to the host adapter does not support SCSI parity;
otherwise, leave it enabled. Most SCSI devices support SCSI parity. If you are unsure if a device supports SCSI parity, consult the
documentation for the device.

Host Adapter SCSI Termination

— Sets termination on the host adapter. The default setting for the Adaptec AIC-7880 host adapters is

Enabled; the default setting for the AIC-7899 host adapter is Automatic. Dell recommends that you leave this option set to the default.

Boot Device Options

The boot device options allow you to specify the device from which to boot your computer:

Boot Target ID

— Specifies the SCSI ID of the device from which you want to boot your system. SCSI IDs are set for the hard-disk drive

according to the drive's location on the backplane board. The default setting for Boot Target ID is SCSI ID 0.

Boot LUN Number

— Allows you to specify a particular logical unit number (LUN) from which to boot your boot device if your boot device

has multiple LUNs and Multiple LUN Support is enabled (see "

Advanced Host Adapter Settings

"). The default setting is LUN 0.

SCSI Device/Configuration Settings

The SCSI device/configuration settings allow you to configure certain parameters for each device on the SCSI bus. To configure a specific device,
you must know the SCSI ID assigned to that device. If you are not sure of the SCSI ID, see "

Using the SCSI Disk Utilities

Initiate Sync Negotiation

— Determines whether the host adapter initiates synchronous data transfer negotiation (synchronous

negotiation) between itself and the device. The default setting is Yes.

Synchronous negotiation is a SCSI feature that allows the host adapter and its attached SCSI devices to transfer data in synchronous

SCSI Parity Checking

Enabled

Host Adapter SCSI Termination

Automatic
