To install SCSI drivers for the optional, integrated redundant arrays of independent disks (RAID) controller in Windows NT 4.0, perform the following steps:

Table 2. AIC-7899 SCSI Controller Settings

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 mode. Synchronous data transfer is faster than asynchronous data transfer.

The host adapter always responds to synchronous negotiation if the SCSI device initiates it. If neither the host adapter nor the SCSI device initiates synchronous negotiation, data is transferred asynchronously.

Normally, you should leave the Initiate Sync Negotiation setting enabled, because most SCSI devices support synchronous negotiation and because it allows for faster data transfer.

NOTE: Some older SCSI-1 devices do not support synchronous negotiation. This may cause your computer to operate erratically or hang if Initiate Sync Negotiation is set to Yes. Set Initiate Sync Negotiation to No for these devices.

• Maximum Sync Transfer Rate — Sets the maximum synchronous data transfer rate that the host adapter supports. The AHA-7899 host adapter supports rates up to 160 megabytes per second (MB/sec), and the AHA-7880 host adapter supports rates up to 40 MB/sec. The default setting for the AHA-7899 is 160 MB/sec (its maximum). The default setting for the AHA-7880 is 20 MB/sec.

If the host adapter is set to not negotiate for synchronous data transfer, the maximum synchronous transfer rate is the maximum rate that the host adapter accepts from the device during negotiation. (This is standard SCSI protocol.)

• Enable Disconnection (sometimes called disconnect/reconnect) — Determines whether the host adapter allows the SCSI device to disconnect from the SCSI bus. Enabling disconnection allows the host adapter to perform other operations on the SCSI bus while the SCSI device is temporarily disconnected. The default setting is Yes.

Leave Enable Disconnection set to Yes if two or more SCSI devices are connected to the host adapter. This optimizes SCSI bus performance. If only one SCSI device is connected to the host adapter, set Enable Disconnection to No to achieve slightly better performance.

• Initiate Wide Negotiation — Determines whether the host adapter attempts 16-bit data transfer instead of 8-bit data transfer. The default setting is Yes.

NOTE: Some 8-bit SCSI devices may have trouble handling wide negotiation, which may result in erratic behavior or a hang condition. For these devices, set Initiate Wide Negotiation to No.

When this option is set to Yes, the host adapter attempts 16-bit transfer. When this option is set to No, 8-bit data transfer is used unless the SCSI device itself requests wide negotiation. The effective transfer rate is doubled when 16-bit data transfer is used because the data path for wide SCSI is twice the size of normal 8-bit SCSI.

• Send Start Unit Command — Determines whether the start unit command is sent to the SCSI device during the boot routine. The default setting is Yes.

Setting this option to Yes reduces the load on your computer's power supply by allowing the host adapter to start SCSI devices one at a time when you boot your computer. When this option is set to No, the devices are allowed to start at the same time. Most devices require you to set a jumper before they can respond to this command.

NOTE: For many devices, if Send Start Unit Command is set to Yes, the boot routine time will vary depending on how long it takes each drive to start.

• BIOS Multiple LUN Support — Provides support for peripherals that contain multiple SCSI devices, such as autoloading tape drives and CD-ROM changers.
  
  
• Include in BIOS Scan — Enables you to set whether the system BIOS scans this device during system start-up. The default setting is Yes.

Advanced Host Adapter Settings

The advanced host adapter settings should not be changed unless absolutely necessary. These values are set by Dell, and changing them may cause conflicts with the SCSI devices.

• Host Adapter BIOS — Enables or disables the host adapter BIOS. The default setting is Enabled.

NOTE: Several SCSISelect options are not valid unless the host adapter BIOS is enabled.

If you are booting from a SCSI hard-disk drive connected to the host adapter, the BIOS must be enabled. You should disable the host adapter BIOS if the peripherals on the SCSI bus (for example, CD-ROM drives) are all controlled by device drivers and do not need the BIOS.

• Support Removable Disks Under BIOS As Fixed Disks — Controls which removable-media drives are supported by the host adapter BIOS. The default setting is Boot Only. The following choices are available.

NOTICE: If a removable-media SCSI device is controlled by the host adapter BIOS, do not remove the media while the drive is on or you may lose data. If you want to be able to remove media while the drive is on, install your removable-media device driver and set this option to Disabled.

• Boot Only —  Only the removable-media drive designated as the boot device is treated as a hard-disk drive.
  
  
• All Disks — All removable-media drives supported by the BIOS are treated as hard-disk drives.
  
  
• Disabled — No removable-media drives are treated as hard-disk drives. In this situation, software drivers are needed because the drives are not controlled by the BIOS.

• Plug and Play SCAM Support — Provides automatic configuration of SCSI devices in operating systems that support Plug and Play. Dell recommends that you leave this option set to Disabled.
  
  
• Reset SCSI Bus at IC Initialization — Enables the SCSI bus to be reset when the controller is initialized. The default setting is Enabled.
  
  
• Extended BIOS Translation For DOS Drives > 1 GB — Determines whether extended translation is available for SCSI hard-disk drives with capacities greater than 1 gigabyte (GB). The default setting is Enabled.

NOTICE: Back up your hard-disk drive before you change the translation scheme. All data is erased when you change from one translation scheme to another.

The standard translation scheme for SCSI host adapters provides a maximum accessible capacity of 1 GB. To support hard-disk drives larger than 1 GB, the 78xx series host adapters include an extended translation scheme that supports hard-disk drives as large as 8 GB, with a maximum partition size of 2 GB under the DOS operating system.

It is not necessary to enable the Extended BIOS Translation setting if you are using another operating system, such as Novell NetWare.

When you partition a hard-disk drive larger than 1 GB, use the DOS fdisk utility as you normally would. Because the cylinder size increases to 8 MB under extended translation, the partition size you choose must be a multiple of 8 MB. If you request a size that is not a multiple of 8 MB, fdisk rounds up to the nearest whole multiple of 8 MB.

• Display <Ctrl><a> Message During BIOS Initialization — Determines whether the Press <CTRL><A> for SCSISelect (TM) Utility! message appears on your screen during system start-up. The default setting is Enabled. If this setting is disabled, you can still run the SCSISelect utility by pressing <Ctrl><a> after the host adapter BIOS banner appears.
  
  
• Multiple LUN Support — Determines whether your system supports booting from a SCSI device that has multiple LUNs. The default setting is Disabled. Enable this option if your boot device has multiple LUNs.
  
  
• BIOS Support For Bootable CD-ROM — Determines whether the host adapter BIOS provides support for booting from a CD-ROM drive. The default setting is Enabled.
  
  
• BIOS Support For Int 13 Extensions — Determines whether the host adapter BIOS supports disks with more than 1024 cylinders. The default setting is Enabled.
  
  
• Support For Ultra SCSI Speed — Determines whether the host adapter supports the fast transfer rates (20–40 MB/sec). The default setting is Enabled.

Starting the SCSISelect Utility

You can start the SCSISelect utility by pressing <Ctrl><a> when the following prompt appears briefly during start-up:

Press <CTRL><A> for SCSISelect (TM) Utility!

The first menu displays the Configure/View Host Adapter Settings and SCSI Disk Utilities options.

Using SCSISelect Menus

SCSISelect uses menus to list options that you can select. To select an option, press the up- and down-arrow keys to move the cursor to the option; then press <Enter>.

In some cases, selecting an option displays another menu. You can return to the previous menu at any time by pressing <Esc>. To restore the original SCSISelect default values, press <F6>.

Using the SCSI Disk Utilities

To access the SCSI disk utilities, select SCSI Disk Utilities from the menu that appears when you start SCSISelect. When the option is selected, SCSISelect immediately scans the SCSI bus (to determine the devices installed) and displays a list of all SCSI IDs and the device assigned to each ID.

When you select a specific ID and device, a menu appears, displaying the Format Disk and Verify Disk Media options.

NOTICE: The Format Disk option destroys all data on the hard-disk drive.

• Format Disk — Runs a utility that allows you to perform a low-level format on a hard-disk drive. Most SCSI disk drives are formatted at the factory and do not need to be formatted again. The Adaptec Format Disk utility is compatible with the majority of SCSI disk drives.
  
  
• Verify Disk Media — Runs a utility that allows you to scan the media of a hard-disk drive for defects. If the utility finds bad blocks on the media, it prompts you to reassign them; if you select Yes, those blocks are no longer used. You can press <Esc> at any time to exit the utility.

Exiting SCSISelect

To exit SCSISelect, press <Esc> until a message prompts you to exit. (If you changed any 78xx series host adapter settings, you are prompted to save the changes before you exit.) At the prompt, select Yes to exit, and then press any key to reboot the computer. Any changes that you made in SCSISelect take effect after the computer boots. (You can select No at the prompt if you are not ready to exit SCSISelect.)

1 Valid for both removable and nonremovable SCSI drives. 
² Valid for removable media only.

Verify Status

The Read After Write Verify option is set to Hardware Level by default. This option cannot be specified in the startup.ncf or autoexec.ncf file. However, the default can be set on the command line. Refer to the NetWare User's Guide for information about using the load command-line options.

The available options are defined in Table 4.

Table 4. Read After Write Verify Options

Option Setting	Function
Disabled	All writes to SCSI disk drives are executed with the SCSI Write command (0Ah or 2Ah).
Hardware Level	All writes to SCSI disk drives are executed with the SCSI Write and Verify command (2Eh) or (if this command is not supported by the drive) with the SCSI Write command (0Ah or 2Ah), followed by the SCSI Verify command (2Fh).
Software Level	Not supported.

Mount Status

Mounting causes a drive to come online as a NetWare storage device. Dismounted drives are inactive and cannot be accessed.

Before you eject the current media, dismount it. When the mount status is Dismounted, eject the media. However, NetWare does not allow you to dismount media that are locked.

To insert your new media, wait for the drive to spin up, and then select the Removable Drive Mount Status option.

Lock Status

If your removable-media device supports the lock/unlock feature, you can lock the media. The media must be in the Not Locked state before you can eject it.

Using Drives Tested and Approved for NetWare

To be fully certified as NetWare "Yes, Tested and Approved," a drive and host adapter must both pass a qualification process that takes place before you see the product. The goals of NetWare testing are to simplify installation and provide the highest quality disk subsystem.

Adaptec 78xx series host adapters and their drivers are fully tested and approved for NetWare. This means that you can purchase a NetWare drive (certified as "Yes, Tested and Approved") from a vendor, connect it to your computer system or host adapter, partition it, and create a volume without any compatibility concerns.

NOTE: Dell recommends using only Dell-tested drives.

Adaptec's adpu160.ham driver module is flexible enough to allow you to connect SCSI drives that are tested and approved for NetWare as well as standard SCSI drives to a single host adapter. The driver registers each hard-disk drive accordingly.

Drive registration is a user-transparent process; no user interaction is required. You can tell that the drive has been detected as NetWare-tested and NetWare-approved if the message NetWare Yes Tested and Approved is included in the drive description string that appears when you run monitor.nlm (disk options).

Using the NetWare Tape Backup Utility

Included with NetWare is a server-based tape backup utility called sbackup.nlm. This allows backup of server disk drives to a server tape drive. The sbackup.nlm utility supports Adaptec host adapters. To load the backup utility, perform the following steps:

1. Load the SCSI adapter driver by entering:
   load [pathname]\adpu160.ham [options] slot=x
   The ASPI layer (aspitran.dsk) is automatically loaded.
   
   
2. Refer to the Novell NetWare documentation for additional instructions on loading the server backup software. Refer to the NetWare Server Backup User's Guide to load the tsa and sbackup modules.

Setting Up a CD-ROM Drive With NetWare 4.2

To use a CD-ROM drive with NetWare 4.2, perform the following steps:

1. Ensure that the CD-ROM driver for NetWare 4.2 (aha2940.ham) is loaded. If necessary, load the driver by entering the following command line:
   load [pathname]\aha2940.ham slot=x
   
   
2. Load cdrom.nlm by entering the following command line:
   load [pathname]\cdrom.nlm
   
   
3. Enter the following line at the prompt and then note the number and name of the CD that appears:
   cd device list
   
   
4. Enter the number or volume name of the CD at the command line:
   cd mount [number]
   or
   cd mount [name]

The CD-ROM drive is now ready to be accessed as a volume.

Troubleshooting for Windows NT

The boot manager for Windows NT contains recovery logic to allow you to return to the last known good configuration. If you have changed your host adapter configuration and Windows NT no longer boots, perform the following steps to recover it:

1. Undo any hardware changes that you have made to the computer since it was last operational.
   
   
2. Reboot the computer. Watch the display carefully during start-up. If the following message appears, press the spacebar, type <l> at the next screen, and then follow the instructions on the screen to continue booting with the last known good configuration:
   
   Press spacebar NOW to invoke the Last Known Good menu
   
   
3. When your computer is operational again, check all of the hardware and software configuration changes that you want to make. Look specifically for conflicts with parts of the existing system configuration that are not being changed.
   
   If you cannot determine the source of the error, contact Dell for assistance. See "Getting Help" in the Installation and Troubleshooting Guide for instructions on contacting Dell for technical assistance.

Troubleshooting for NetWare

Any error that occurs while the driver is initializing prevents it from loading. If an error does occur, the driver causes the computer to beep and then display the following numbered error message:

xxx message

The xxx indicates the error code, and message is a descriptive line describing the error. The error codes are divided into three categories:

• 000-099 — Non-host-adapter specific
  
  
• 100-299 — Host-adapter specific
  
  
• 300-999 — Reserved

Specific error codes, such as those in the following subsections, appear only if you have installed the host adapters and drivers that generate them.

Non-Host-Adapter Specific Error Codes

The following error codes alert you to error conditions caused by factors not related to the host adapter:

000 Failed ParseDriverParameters call

A call to NetWare's ParseDriverParameters routine has failed for some unknown reason. The command line contains errors, or you pressed <Esc> at the port or slot prompt.

001 Unable to reserve hardware, possible conflict

The driver failed in its attempt to reserve the host adapter's hardware settings (that is, direct memory access [DMA] and interrupt request [IRQ] settings). Another card in your system may be causing a conflict with the host adapter.

002 NetWare rejected card Failed AddDiskSystem call

The driver failed in its attempt to register the host adapter with NetWare. The file server may not have enough memory.

003 Invalid command line option entered > option

An invalid option was entered on the command line. The invalid option that was entered is also displayed.

004 Invalid command line, please enter correctly

The driver was unable to understand the command line options that you entered. Be sure that you have entered these options correctly.

Host-Adapter Specific Error Codes

The following error codes alert you to error conditions caused by factors related to the host adapter:

200 No host adapter found for this driver to register

No Adaptec 78xx host adapter was found in your computer for the driver to register. Be sure that the host adapter is properly configured and properly seated in the slot.

203 Invalid 'device' setting

You have entered an invalid slot setting on the command line. You can only enter slot numbers for valid host adapters. If you load without the slot option, you will be prompted to enter a valid value.
