I. INTRODUCTION I. INTRODUCTION (Sections/Checklist) How this manual is organized This manual is divided into the following sections: I. II. III. IV-IX. Introduction: Features: Installation: Driver Setup: Manual information and checklist Information and specifications. Instructions on setting up the ASUS PCI-SC875. SCSI driver and utility installation and usage. Item Checklist Please check that your package is complete. If you discover damaged or missing items, please contact your retailer.
II. FEATURES Features of the ASUS SCSI Card The ASUS PCI-SC875 is carefully designed for the demanding PC user who wants a high-end SCSI card for 8-bit and 16-bit SCSI devices. This SCSI card: II.
III. INSTALLATION This section explains how to physically install the SCSI card in your computer and connect SCSI devices to it. You may need to run your computer’s Setup program as part of the installation process. After the host adapter is physically installed, you can change its configuration with the SDMS SCSI utility You can install multiple SCSI cards in your computer if enough PCI bus slots are available. Each SCSI card has two separate SCSI channels.
III. INSTALLATION 5. Position the host adapter directly over the PCI slot and insert the end of the board in the card guide. Carefully press the bus connector on the bottom of the host adapter down into the slot. Be sure the metal contacts on the bottom of the host adapter are securely seated in the slot. III. INSTALLATION (SCSI Cables) 6. Attach the host adapter bracket to the computer chassis with the screw from the slot cover that you removed in step 4.
III. INSTALLATION Maximum Cable Lengths To assure reliable operation, the total length of the SCSI bus, including both internal and external cabling, should not exceed 6meters (19.7 feet) for synchronous or asynchronous data transfer rates, and 3meters (9.8 feet) for UltraSCSI data transfer rates. WARNING: This SCSI controller support only single-ended SCSI devices. Differential SCSI devices may be damaged if you connect them to the SCSI bus.
III. INSTALLATION The following illustrations show the 50pin internal connector used with the ASUS PCI-SC875. 68-pin Wide-SCSI connectors may also be used with Wide-SCSI devices. To connect internal SCSI devices, follow these steps: 1. Plug the SCSI connector at one end of the SCSI ribbon cable into one of the host adapter’s internal SCSI connectors. Line up the colored stripe on the ribbon cable with the number 1 printed below the connector on the host adapter. This is called maintaining pin-1 orientation.
III. INSTALLATION Connecting External SCSI Devices You can daisy-chain up to seven SCSI devices to the internal 50-Pin connector. You can daisy-chain up to fifteen SCSI devices to the internal or external 68-Pin connector. There is a limiation of a total of 15 SCSI devices per ASUS PCI-SC875 card. Daisy-chaining means connecting multiple devices with multiple cables.
III. INSTALLATION Connecting External 8-bit and 16-bit Devices When daisy-chaining external 8-bit and 16-bit devices with standard SCSI-2 connectors to the ASUS PCI-SC875, use an external SCSI-2 male 68-pin to SCSI-2 female 50-pin converter. Follow these steps: 1. Daisy-chain all 16-bit devices together with external SCSI-2 Wide cables. 2. Daisy-chain all 8-bit devices together with external SCSI-2 Narrow cables. 3.
III. INSTALLATION SCSI IDs Each device on the SCSI bus, including the host adapter, must have a unique SCSI ID. The SCSI ID serves two purposes: • • It uniquely defines each SCSI device on the bus. It determines which device controls the bus when two or more devices try to use it at the same time. SCSI IDs on one channel do not interfere with the IDs on another channel. This applies to two SCSI host adapters that implement different buses as well as dual channels on a single host adapter.
III. INSTALLATION SCSI Bus Activity LED Connector Most computers have an LED disk activity light on the front panel. If you disconnect the cable from the motherboard and attach it to the LED connector on the host adapter, the LED will light whenever there is activity on either SCSI channel. Follow these steps to connect the LED cable to the host adapter: 1. Refer to your computer’s documentation to locate the LED cable and unplug it from the connector on the motherboard. 2.
IV. CONFIGURATION Configuring Your Host Adapter In most cases you should not need to change the default configuration of your host adapter. You may decide to alter these default values if there is a conflict between device settings, or if you need to optimize system performance. To perform the configuration described in this chapter you must have SDMS BIOS version 4.xx.xx or higher, and it must include the Symbios Logic SCSI Configuration utility.
IV. CONFIGURATION Main Menu When you start the Symbios Logic Configuration Utility, your computer monitor displays the Main menu. This menu is your entry to the utility. The Main menu displays a list of up to four Symbios Logic PCI to SCSI host adapters in you system, and information about each of them. By using the arrow keys, an adapter is selected to view and/or change current settings for the adapter, and the SCSI devices attached to it. An adapter is selectable only if the current status is “On”.
IV. CONFIGURATION Adapter Utilities Menu When you select a host adapter from the Main menu, you will see new screen. Choose “A-Adapter Setup” to view and change the selected adapter settings. Choose “D-Device Selections” to view and change settings for the devices attached to the selected adapter. You come back to this menu after making changes to the configuration of any host adapter or connected SCSI device. Before you exit this menu, you are prompted to save or cancel the changes.
IV. CONFIGURATION Device Setup Menu When you select a specific device from the Device Selections menu, your computer monitor displays a new menu. The settings in this menu affect individual SCSI devices attached to the selected host adapter. Changes made from this menu do not cause the sytem to reboot upon exit from the SCSI Configuration utility. Sync Rate (Mega Bytes/sec) - The value set with this option defines the maximum transfer rate the host adapter attempts to negotiate.
V. DOS/WINDOWS DRIVERS Introduction In SDMS 4.0, the SCSI BIOS for the Symbios Logic family of PCI SCSI chips is capable of mapping SCSI hard disk drives behind any non-SCSI hard disk drives (IDE, ESDI, etc.) within the same system. A driverless solution will allow connection of up to 24 hard drives (SCSI and non-SCSI) under DOS 5.0 and above. Full Virtual DMA Services (VDS), including features such as scatter-gather, are also supported by the SCSI BIOS.
V. DOS/WINDOWS DRIVERS ASPI8XX.SYS Driver Features • • • • • • • • • • Supports Advanced SCSI Programming Interface (ASPI) applications Supports single-threaded I/O Supports up to four host adapters Releases initialization code for smaller runtime size Performs synchronous negotiation (including Fast-20) Performs Wide SCSI negotiation Full VDS (Virtual DMA Services) support, including scatter-gather Allows Disconnect/Reselect Supports adapter exclusion Allows shared interrupts Description ASPI8XX.
V. DOS/WINDOWS DRIVERS Installing Your ASPI8XX.SYS Driver 1. Use the COPY command to copy the ASPI8XX.SYS driver from the SDMS SCSI Drivers disk to your boot disk. 2. Add this line to your system’s CONFIG.SYS file: DEVICE=C:[path]ASPI8XX.SYS This line must appear before any line loading other ASPI drivers (like SYMCD.SYS, SYMDISK.SYS, or any other ASPI compliant driver/application). Command Line Options The ASPI8XX.
V. DOS/WINDOWS DRIVERS Using the /DISCONNECT (or /DC) Option SCSI devices have the ability to disconnect from the bus during an I/O transfer. This option is used to allow a device to disconnect. If a particular host adapter has parity checking disabled, all devices attached to it must have disconnects disabled, since parity is required during the reselection phase. Valid options are ON (allow disconnects) or OFF (do not allow disconnects). The default for all devices is ON.
V. DOS/WINDOWS DRIVERS For example, to turn off parity checking on the first host adapter (boot order designation = 0), the line in your CONFIG.SYS file that loads ASPI8XX.SYS should look like this: DEVICE=C:[PATH]ASPI8XX.SYS /PARITY=OFF<0> Using the /EXCLUDE (or /X) Option This option allows you to exclude support for an adapter that does not currently have BIOS support. You may not exclude an adapter that is supported (included) by the BIOS when you boot your system.
V. DOS/WINDOWS DRIVERS Using the /SCAM Option This option allows you to disable support for the SCSI Plug and Play protocol called SCAM (SCSI Configured AutoMatically). SCAM support is ON by default. You may change the SCAM setting only if the path (adapter) specified is not controlled by the BIOS. Option Syntax: /SCAM=n[,n]* For example, to turn off SCAM support on the second host adapter (boot order designation = 1), the line in your CONFIG.SYS file that loads ASPI8XX.
V. DOS/WINDOWS DRIVERS Troubleshooting System Locks up during bootup a. Check for conflicts with other ASPI managers. b. Check for correct loading sequence in the CONFIG.SYS file. c. Boot the system. V. DOS/WINDOWS (Troubleshooting) The device driver does not recognize one of the non-boot SCSI peripherals (system may lock up) a. Make sure the drivers were installed in the correct sequence. b. Make sure the drivers CONFIG.SYS line has the correct path to the drivers. c. Power down all units in the system.
V. DOS/WINDOWS DRIVERS SYMDISK.SYS Driver Features • • • • • • • • Supports removable media devices Supports magneto optical devices Supports non-512-byte sectors (1024, 2048, 4096) Supports multiple logical unit number (LUN) support Supports multiple host adapters (with ASPI8XX.SYS) Can reserve drive letters for installed devices without media present in the device (see /UNITS under Command Line Options) Can add drive letters Supports power management (to spin down drives) Description SYMDISK.
V. DOS/WINDOWS DRIVERS Installing Your SYMDISK.SYS Driver 1. Use the COPY command to copy the appropriate drivers from the SDMS SCSI Drivers disk to your boot disk. 2. Add the lines shown below to your system’s CONFIG.SYS file. The ASPI8XX.SYS driver is also required. List the drivers in this sequence: DEVICE=C:[PATH]ASPI8XX.SYS DEVICE=C:[PATH]SYMDISK.SYS Command Line Options The SYMDISK.SYS device driver has several embedded functions which are accessed via switches on the command line.
V. DOS/WINDOWS DRIVERS For example, if there is a removable media drive at the first host adapter set to SCSI ID 2, and you need to reserve three partitions, the command line should look like this: DEVICE=C:[PATH]SYMDISK.SYS /UNITS=0:2:0:3 When SYMDISK.SYS initializes, it will default to either: a. One drive letter for a removable media device with no media present. b. The number of partitions found on the media in the removable media device.
V. DOS/WINDOWS DRIVERS Using the /SPINDOWN= Option This is a power management feature that can automatically spin down a disk when the disk is not accessed for a specified amount of time. The default spindown time is 15 minutes. You can specify a new spindown time in hours and minutes (hh:mm) with a minimum time of 1 minute. To use this option, the line in CONFIG.SYS that loads SYMDISK.SYS should look like this: DEVICE=C:[PATH]SYMDISK.
V. DOS/WINDOWS DRIVERS Troubleshooting THE COMPUTER LOCKS UP AND WILL NOT COMPLETE BOOTING FROM A NON-SCSI HARD DISK DRIVE a. Refer to the drive manufacturer’s user manual. THE COMPUTER LOCKS UP AND WILL NOT COMPLETE BOOTING FROM A SCSI HARD DISK DRIVE a. Is the SCSI BIOS seen during boot? NOTE: If the SCSI BIOS is seen during boot, a banner similar to the following appears: Symbios Logic SDMS(TM) v4.0 PCI SCSI BIOS, PCI Rev.2.0,2.1 Copyright 1995 Symbios Logic PCI-4.xx.xx YES NO V.
V. DOS/WINDOWS DRIVERS b. Does the SCSI BIOS see the bootable SCSI drive? NOTE: When the computer boots, SDMS scans the SCSI bus. Devices found on the SCSI bus are identified as in the following lines: HBA 0 0 ID LUN 2 0 7 0 VENDOR SEAGATE Symbios PRODUCT ST31230N SYM53C875 REV 0060 0003 .... .... .... YES NO Go to c. Power down all units in the system. Make sure the hard drives have different ID numbers (boot drive should have lowest ID). Make sure both ends of the SCSI bus are terminated.
V. DOS/WINDOWS DRIVERS SYMCD.SYS Driver Features • • • Compatible with Microsoft’s CD-ROM Extension 2.21 and above Multi-session Photo CD support Support for reading CCDA disks Description SYMCD.SYS is needed whenever a CD-ROM device is connected on the SCSI bus. You must load it in conjunction with Microsoft’s CD-ROM Extension 2.21 or above (MSCDEX.EXE). SYMCD.SYS communicates through ASPI8XX.SYS, so you must load ASPI8XX.SYS to use SYMCD.SYS. Installing Your SYMCD.SYS Driver 1.
V. DOS/WINDOWS DRIVERS Command Line Options The SYMCD.SYS device driver has several embedded functions available, which are accessed via switches on the command line. An explanation of these options follows. IMPORTANT: No spaces are allowed in specifying these command line options. Spaces are required between different command line options. Using the /ASK Option This option prompts the user at initialization time whether to load SYMCD.SYS or not. For example, the line in CONFIG.SYS that loads SYMCD.
V. DOS/WINDOWS DRIVERS WIN8XX.386 Driver Features • • • Supports Windows Advanced SCSI Programming Interface (ASPI) applications Supports 32-bit Disk Access in Windows 3.1 and Windows for Workgroups 3.11 via the FastDisk interface Processes all I/O requests, including ASPI requests, using 32-bit protectedmode code for the highest possible performance Description WIN8XX.386 is both a Windows FastDisk driver and an ASPI Manager for Windows which provides an interface to popular ASPI applications.
V. DOS/WINDOWS DRIVERS This entry may or may not already exist in your SYSTEM.INI file, depending on the hardware present when you installed Windows. This entry controls the loading of the standard FastDisk driver that ships with Windows for the purpose of providing 32-bit Disk Access to an IDE drive. This driver is not compatible with vendor-supplied FastDisk drivers, such as WIN8XX.386. 6. Use the COPY command to copy the WIN8XX.DLL driver from the SDMS SCSI Drivers disk to your boot disk.
V. DOS/WINDOWS DRIVERS Using the SYNCHRONOUS Option Synchronous=ON or OFF (Default = ON) This option allows you to turn off SCSI synchronous transfers. By default they are on, which is faster. However, if you are having problems with your system you might want to try turning synchronous off. Using the WIDE Option Wide=ON or OFF (Default = ON) This option allows you to turn off SCSI wide transfers. By default they are on, which is faster if you have a wide disk drive.
V. DOS/WINDOWS DRIVERS This option allows you to turn off the FASTDISK portion of this driver. The FASTDISK portion allows 32-Bit Disk Access on a SCSI drive at C: or D:. Since Windows only allows 32-Bit Disk Access on one kind of drive at a time, you may want to disable it for your SCSI drive so you can use it on an IDE drive you have in your system. This allows the ASPI portion of the driver to continue to function, while the FASTDISK (32-Bit Disk Access) portion is disabled.
V. DOS/WINDOWS DRIVERS Troubleshooting WINDOWS DISPLAYS THE FOLLOWING MESSAGE WHILE BOOTING: The Microsoft Windows 32-bit disk driver (WDCTRL) cannot be loaded. There is unrecognizable disk software installed on this computer. a. Make sure the line controlling WDCTRL in your SYSTEM.INI is either removed or commented out, as explained in the driver installation instructions. b. Re-boot the system. THE DRIVER DOES NOT RECOGNIZE ONE OF THE NON-BOOT SCSI PERIPHERALS (system may lock up) a.
V. DOS/WINDOWS DRIVERS Important Additional Information For Windows Enabling 32-bit Disk and File Access in Windows Only Windows for Workgroups 3.11 offers both 32-bit Disk and File access. To enable these features, make sure your system is backed up, then do the following: 1. 2. 3. 4. 5. Select the Control Panel applet in the Main program group. Select the 386 Enhanced icon. Select the Virtual Memory settings. Select the Change button.

VIII. NETWARE DRIVERS Introduction The Symbios Logic SDMS drivers for the Novell Netware operating system allow you to utilize a Symbios Logic SCSI controller or processor, controlled by a Symbios Logic SCSI BIOS, with NetWare. The SDMS software, coupled with a Symbios Logic SCSI controller or processor, provides a SCSI solution within the NetWare environment. Separate drivers are provided for Novell NetWare v3.12, and Novell NetWare v4.xx.
VIII. NETWARE DRIVERS Description There is a separate SDMS device driver and ASPI manager for each of two major releases of NetWare. For NetWare v3.12, the SDMS device driver is SDMSNET3.DSK, and the file NETASPI3.NLM is loaded if support for the ASPI interface is desired (this is required for devices such as tape drives). For NetWare v4.xx, the SDMS device driver is SDMSNET4.DSK, and the file NETASPI4.NLM is loaded if support for the ASPI interface is desired.
VIII. NETWARE DRIVERS For NetWare v3.12 New Installations NOTE: The SDMSNET3.DSK driver should work on a NetWare 3.11 server. However, this compatibility is neither tested nor supported. VIII. NETWARE (Installation) 1. Create a directory in which to install the NetWare file server. Change to that directory and copy all the files from the NetWare system disks into that directory. 2. Copy the file SDMSNET3.DSK from the Symbios Logic device drivers diskette into this directory.
VIII. NETWARE DRIVERS For NetWare v4.xx New Installations VIII. NETWARE (Installation) 1. Begin the file server installation as per the instructions in the file server installation chapter in the Novell NetWare Installation Manual. 2. When the NetWare installation procedure prompts you for a disk driver, insert the Symbios Logic device drivers diskette into drive a: or b:. Then use the INS key to select an unlisted driver. A dialog box appears.
VIII. NETWARE DRIVERS For NetWare v4.1x NWOS2 Installations This is not a supported configuration. Command Line Options The SDMSNET3.DSK and SDMSNET4.DSK drivers have many tuning parameters. Following is a list of tuning parameters available, including the default option and a list of valid options. Following each parameter is a description of when to use a parameter, and any impact its use/disuse might incur. If an option is specified but the assignment is not valid, then the default value is used.
VIII. NETWARE DRIVERS Enabling this option results in the driver issuing tagged IO requests to the devices that support tagged queuing. Devices that do not support tagged queuing are not issued tagged requests. Depending on the drive controller, throughput of the device is increased by the use of queue tags. However, the optimal number of queue tags is based on the specific device type. VIII.
VIII. NETWARE DRIVERS Using the Base Time-Out Option Command line option: timeout=
VIII. NETWARE DRIVERS This option allows the user to disable support of wide SCSI when using a wide SCSI controller. Set this option to “disable” if a wide SCSI device is present on the system, but a narrow SCSI cable is connected somewhere on the bus between the wide SCSI host adapter and the wide device, thus prohibiting the transfer of wide data. If this option is set to “disable”, the wide device still works, but all data transferred to/ from the device is narrow (8 bit).
VIII. NETWARE DRIVERS VIII. NETWARE (Command Lines) Using the Exclusion of Devices Option Command line option: xcl=[:device ...] Default value: All devices recognized by the driver, i.e. no devices are excluded. Valid options: p,i,l (You may specify multiple devices with a colon separator) where p is the Path designator, and is in the range 0 -7, i is the SCSI ID designator, and is in the range 0 -31, l is the LUN designator, and in the range 0 -7. The LUN parameter is optional.
VIII. NETWARE DRIVERS NOTE: The following three options affect the amount of memory used by the driver. For information on how memory is allocated by the driver, and to get an approximate feel for the amount of memory which is saved by invoking these parameters, refer to Memory Allocation under Important Additional Information at the end of this section. If the product of max_hbas * max_id * max_lun is small (less than 100), system performance may suffer.
VIII. NETWARE DRIVERS Using the Maximum LUNs Option Command line option: max_lun=
VIII. NETWARE DRIVERS Using the PMMAKE.NLM Utility The PMMAKE.NLM utility is used to compile a power management schedule file from a standard text file, which you can create using the NetWare EDIT utility, or some other editor. Place the text file in the SYS:\PM directory on the server. The format for this text file is given below.
VIII. NETWARE DRIVERS For example: B00I01L01, I02, I03, I04, B01I00, I01,I02 specifies Devices ID 01 LUN 01, ID 2, ID 3, ID 4 on Bus 0 Devices ID 0, ID1, ID 2 on Bus 1 Here is a PMMAKE sample input file: VIII.
VIII. NETWARE DRIVERS Using the PMSCHED.NLM Utility You must load the PMSCHED.NLM utility to activate power management for devices controlled by the SDMSNETx.DSK driver. The syntax for the line that loads the PMMAKE utility is: load PMSCHED [] where is the name of the power management configuration file to use. If no file is specified, PMSCHED looks for SYS:\PM\PM.CFG. If PM.CFG is not found, PMSCHED loads for manual operation of power management.
VIII. NETWARE DRIVERS Device Statistics Device statistics are gathered on all devices registered by SDMSNETx.DSK with the NetWare operating system. These statistics record the number of reads and writes performed on a device and, if the device is power manageable by the SDMS driver, the number of times the device is spun up and spun down. Statistics are viewed, toggled on and off, or reset from the power management utility PMSCHED.NLM.
VIII. NETWARE DRIVERS Optimal Use of Command Line Options Peripheral Device Dependent Optimizations Some devices support SCSI tagged queue commands very efficiently, while others show a significant loss of performance when the number of queued requests exceed a certain value. (qtags, qdepth, qtag_type) Most disk drives have an onboard read cache that is used by the drive controller to read ahead data.
VIII. NETWARE DRIVERS VIII.
VIII. NETWARE DRIVERS DOS Drivers Not Supported The following SDMS DOS drivers are not supported in the NetWare Environment. • ASPICAM.SYS • SYMDISK.SYS • MINICAM.SYS • SCSIDISK.SYS • DOSCAM.SYS • CDROM.SYS When Using An SDMS 4.XX BIOS The SDMS 4.XX BIOS supports two different configurations - default Boot configuration and NVRAM configuration. Both configurations are supported. Default Configuration VIII. NETWARE (Additional Information) In default boot configuration, the 4.

SCO UNIX DRIVERS Procedure 1 Existing System Installation If you plan to attach SCSI devices to a Symbios Logic host adapter while using a non-SCSI hard drive (IDE, ESDI, ST506) as the boot hard drive already containing a SCO UNIX system, execution of procedure 1 is all that is necessary. This installs the Symbios Logic driver on the non-SCSI boot drive. Some of the SCSI devices supported include tape drives, CD-ROM drives, and SCSI hard disk drives used as secondary storage.
IX. SCO UNIX DRIVERS Installing Your SCO UNIX Driver Existing System Installation This procedure assumes SCO UNIX is already installed on a hard disk drive. This installation is necessary to build a new UNIX kernel which includes the proper Symbios Logic host adapter driver. The basic steps for accomplishing this are outlined below. For more details on UNIX installation, refer to the SCO UNIX System Administrator’s Reference manual. ASUS PCI-SC875 User’s Manual IX.

Unless this is desired, type n and press Enter. A prompt appears to add a high-sierra file system. Type y and press Enter. The system displays the High Sierra/ISO9600 file system Configuration Program menu. Select option 1 to add high-sierra and press Enter.
IX. SCO UNIX DRIVERS New System Installation This procedure installs SCO UNIX onto a hard disk drive. This installation is necessary to build a new UNIX kernel that includes your Symbios Logic driver. For more details on UNIX installation refer to the SCO UNIX System Administrator’s Reference manual. IX. SCO UNIX (Installation) 1 Link the Symbios Logic BTLD into the UNIX kernel during installation. a. Insert the SCO UNIX installation diskette and reboot the system. For SCO 3.
IX. SCO UNIX DRIVERS Troubleshooting The following conditions should exist after a successful installation: 1. The directory etc/conf/sdevice.d should contain a file named bhba or slha, depending on your SCO UNIX version. This file contains the sdevice entries. 2. The directory etc/conf/cf.d contains files sdevice, mdevice, and mscsi. Files sdev.hdr and mdev.hdr describe the values of the possible field entries in the files sdevice and mdevice, respectively. a.

X. UNIXWARE DRIVERS 3. Insert the SDMS PCI UnixWare driver diskette when prompted to insert the Host Adapter diskette and press Enter. When the driver is loaded, a message “C8xx driver isloaded” appears on the screen. If you want to install other host adapter drivers, then insert the IHV HBA diskette provided with the UnixWare distribution package and press Enter. 4. Follow instructions on the screen or refer to the UnixWare Installation Handbook to complete installation.
X. UNIXWARE DRIVERS Loading the Package Before you install the C8xx driver, make a backup copy of the existing kernel by: 1. Log on as root. 2. At the shell prompt type cp /stand/unix /stand/unix.good Use this copy of the old kernel to reboot the system if the driver installation fails. Refer to the later section titled Troubleshooting for more information. 3. Once the old kernel is saved, insert the SDMS PCI UnixWare driver diskette. 4.
X. UNIXWARE DRIVERS Loading Loadable Module 1. Once the loadable driver is configured into the system, your driver is ready to load into the running system using the modadmin command as follows: modadmin -l c8xx NOTE: When the driver is loaded, it scans the SCSI bus and displays the devices found on it. An integer module-id used to identify the C8xx driver is displayed on the screen when loading completes. 2.
