************************************************ * >>>> Unisys SCSI Disk Driver READ.ME <<<< * ************************************************ ____________________________________________________________________ Unisys SCSI Disk Driver (UNIDRIV.DSK version 1.03) for NetWare 386 Version 3.1 October 3, 1990 ____________________________________________________________________ 1.0 CONTENTS It is intended that the information contained in this document be used in conjunction with the manuals provided by Novell, Inc. for NetWare 386. Information which is specific to the Unisys U6000 and PW2 SCSI/VGA combination card is provided. This documentation applies to the Unisys SCSI Disk Driver, "UNIDRIV.DSK". This driver is designed to work with: o Unisys U6000/55 system internal SCSI adapter o Unisys U6000/60 system internal SCSI adapter o PW2 systems with (PW2-MCC) SCSI/VGA multi-function board The following files are supplied with this release to support the hardware noted above: File Name Size in Bytes Date Stamp Time Stamp ------------ --------------- ---------- ---------- UNIDRIV DSK 12782 10-03-90 1:23p SSTBIO SYS 18544 6-12-90 4:30a Application and utility software supplied by Novell or other vendors which are designed to run in the NetWare environment should be installable and executable when the Unisys SCSI driver is in use. 1.1 HARDWARE LIMITATIONS The U6000 will support upto 12 MB of memory when used with this driver. More than 12 MB may be installed on this machine. Any amount above 12 MB will not be used. Up to 10 MB of memory can be supported on PW2 500 systems. This release of the SCSI disk driver does not support SCSI tape for any of the Unisys systems. Only one SCSI adapter is supported by this driver. Up to 7 disks are supported on the SCSI bus. 2.0 NETWARE SETUP STEPS The procedure used for installation of NetWare 386 is documented in the NetWare 386 Installation Manual. For a new installation, make sure the disks are properly addressed and connected to the SCSI bus. Run diagnostics to ensure that all disks are recognized properly. All drives should be formatted if not formatted previously. Drive C should have DOS installed on a small (2 MB) partition. For systems using the VGA/SCSI Combo card, SSTBIO.SYS should be loaded via the CONFIG.SYS file. Copy the SSTBIO.SYS from the Supplemental Driver Diskette to the drive C DOS partition and update the CONFIG.SYS file to include the following line: DEVICE=SSTBIO.SYS If SSTBIO.SYS is not used, files will not be loadable from the DOS partition and COMMAND.COM will not be accessible when the server exits NetWare to return to DOS. 2.1 CONFIGURING THE CONTROLLER CARD U6000 systems do not require jumper settings for use with the NetWare 386 driver. The SCSI adapter does not utilize AT interrupt vectors in the IRQ range. The following I/O port addresses are used by the SCSI adapter: 0CC0, 0CC4. The SCSI/VGA adapter provided in the PW2-MCC configurations of the PW2-500 systems removes the need for a separate video adapter. No special hardware setup is required. The VGA adapter is always the primary video adapter and uses the default VGA I/O address range, it also uses 46E8h and 0102h for reset. A serial port is included in the VGA/SCSI card. For NetWare installations, this port should be disabled to prevent it from conflicting with other serial ports in the system. The SCSI portion of the adapter uses a default of IRQ 14, DMA channel 3, I/O ports 340-348 and BIOS address of DC000h. Jumpers should be installed according to the following table: Jumpers ON Jumpers OFF ---------- ----------------------- P3, P8 P4, P5, P6, P10, P12 P11 (lower pins) P9 (disable Serial Port) 2.2 DRIVER INSTALLATION Initial installation of this driver requires the use of a Supplemental Driver Diskette for NetWare 386 version 3.1. This diskette contains the driver file executable file named "UNIDRIV.DSK". This file should be copied to the same directory where the NetWare server.exe file is installed. Follow the instructions in the installation manual for NetWare 386. After starting the server by running "SERVER" from the DOS prompt (page 188, section 1) use the procedure for server setup. Next, refer to page 190, section 1a. and enter "LOAD UNIDRIV" to load the driver. The driver does not display prompts for options such as I/O port addresses and interrupt settings. All hardware specific parameters built into the driver itself. A message will be displayed which identifies the Unisys SCSI Disk Driver during its initialization phase. All other instructions for the installation process should be taken directly from the NetWare 386 Installation Manual. It supplies detailed information on the installation and setup procedure for the NetWare 386 operating system. For references to the disk driver file, use the name "UNIDRIV.DSK". 2.3 ERROR MESSAGES "SCSI Adapter operation failure" The adapter hardware is not functioning properly. Contact service personnel for assistance. "SCSI Driver configuration conflict" I/O ports, DMA utilization setup interferes with other system resources. Some other driver is using settings required for the Unisys driver. "SCSI Driver disk interrupt error" IRQ setting interferes with other system resources. Some other driver is using an interrupt level required by the Unisys driver. "SCSI Driver initialization error" NetWare is unable to initialize the driver. A system or memory problem may be indicated. NetWare files may be corrupted. 3.0 CUSTOMER SUPPORT Technical support for the installation and operation of this driver software is available by calling the Unisys Support Center in Lavonia, Michigan (telephone # 800/521-9550). 4.0 DRIVER UPDATES Information on the distribution of new drivers is available by calling the Software Integration Group at Unisys in San Jose, California (telephone # 408/434-2600). 5.0 INSTALLATION MANUALS Contact your Unisys salesperson to get installation manuals and updated information on driver supplements. ____________________________________________________________________
