QLogic Fast!SCSI PCI Basic ADD Driver for OS/2 Version 1.02 January 9, 1995 * This release has been tested with OS/2 Version 2.1 and OS/2 Warp Version 3 * The following files are on this disk for supporting OS/2: \OS2\QL510.DDP Device driver profile script required for the OS/2 Device Driver Install utility \OS2\QL510.ADD OS/2 ADD driver for QLogic Fast!SCSI PCI Basic host adapter \OS2\README.TXT This file * To initially install OS/2 on a SCSI disk attached to the Fast!SCSI PCI Basic adapter or to install OS/2 from a CD-ROM player attached to the Fast!SCSI PCI Basic adapter: Installing OS/2 Version 2.1: 1. Make a copy of the IBM OS/2 Diskette 1 (use diskcopy command) 2. Copy the QL510.ADD file from the \OS2 directory on the QLogic driver diskette onto the root directory on the copy of the OS/2 Diskette 1 3. Edit the CONFIG.SYS file located on the copy of OS/2 Diskette 1, add the following statement to the end of the file: BASEDEV=QL510.ADD 4. Start the installation by inserting the IBM OS/2 Installation Diskette into drive A and restarting the system, use the modified copy of Diskette 1 when prompted to insert Diskette 1 Installing OS/2 Warp Version 3 from CD-ROM: 1. Make a copy of the IBM OS/2 Warp Diskette 1 (use diskcopy command) 2. To make room for the QLogic driver, delete the following files from the copy of Diskette 1: For an ISA/EISA (non-Micro Channel) computer, delete: IBM2*.* For a Micro Channel computer, delete: IBM1*.* 3. Copy the QL510.ADD file from the \OS2 directory on the QLogic driver diskette onto the root directory on the copy of the OS/2 Diskette 1 4. Edit the CONFIG.SYS file located on the copy of OS/2 Diskette 1: a. Insert the letters REM before any lines in the CONFIG.SYS that refer to the files deleted in step 2 above b. Add the following statement to the end of the file: BASEDEV=QL510.ADD 5. Start the installation by inserting the IBM OS/2 Installation Diskette into drive A and restarting the system, use the modified copy of Diskette 1 when prompted to insert Diskette 1 Installing OS/2 Warp Version 3 from diskettes: 1. Start the installation by inserting the IBM OS/2 Installation Diskette into drive A and restarting the system, insert other diskettes as requested 2. During the installation from diskette, select "Advanced Installation" 3. When the System Configuration window is displayed, select the CD-ROM Device Support icon and then select the type of CD-ROM device to be supported 4. After completing the OS/2 installation from diskettes, follow the procedure below to install the QLogic ADD driver using the Device Driver Install utility * To install the QLogic Fast!SCSI PCI Basic ADD driver on previously installed OS/2 system: 1. Boot up OS/2 system 2. Insert QLogic SCSI driver diskette into drive A (or B) 3. Select "System Setup" from OS/2 System program group 4. Select "Device Driver Install" from the System Setup group 5. Change source directory to A:\OS2 (or B:\OS2) 6. Select "Install" 7. Select the "QLogic Fast!SCSI PCI Basic ADD Driver" followed by "OK". The driver will be copied to your boot disk and your CONFIG.SYS file will be updated 8. You must reboot your system after installing the driver * OS/2 currently does not support removable SCSI disk devices. The QLogic ADD driver provides limited support for these devices by treating them like a fixed disk device. The disk media must be inserted when booting OS/2, and the system must be rebooted when changing the disk media. To enable removable disk support, add the /!R parameter to the BASEDEV= command in your CONFIG.SYS file as follows: BASEDEV=QL510.ADD /!R * The QLogic Fast!SCSI PCI Basic ADD driver uses the following default SCSI parameters: Maximum logical units per ID 8 (all 8 LUNs are scanned at each ID) Initiator ID 7 Synchronous negotiation ENABLED Disconnects ENABLED Parity checking ENABLED SCSI bus reset at boot ENABLED * The following command line parameters are supported by the QLogic Fast!SCSI PCI Basic ADD driver: (add to end of BASEDEV=QL510.ADD line in config.sys file) /A:d Specifies which adapter (0-2) that following command line parameters apply to. /I Ignore the specified adapter (must follow "/A:d" parameter). /DM /!DM Enable/disable DASD manager support for specified adapter and/or devices (add ":d,d,d" to specify list of SCSI IDs or ":(d,d),(d,d),(d,d)" to specify ID,LUN pairs). Default is enabled. /SM /!SM Enable/disable SCSI manager support for specified adapter and/or devices (add ":d,d,d" to specify list of SCSI IDs or ":(d,d),(d,d),(d,d)" to specify ID,LUN pairs). Default is enabled. /!R Report removable disk devices to OS/2 as fixed disks. By default removable disks will be reported as removable. /SI:d Specify SCSI initiator ID to use on specified adapter. Default is SCSI ID 7. /SR /!SR Enable/disable SCSI bus reset during boot on specified adapter. Default is enabled. /ET /!ET Enable/disable embedded target support for specified adapter. Default is enabled (all 8 LUNs supported). Specify /!ET for supporting LUN 0 only. /PAR /!PAR Enable/disable SCSI bus parity checking on specified adapter. Default is parity enabled. /SN /!SN Enable/disable synchronous negotiations for specified adapter and/or devices (add ":d,d,d" to specify list of SCSI IDs or ":(d,d),(d,d),(d,d)" to specify ID,LUN pairs). Default is enabled. /SD /!SD Enable/disable SCSI disconnects for specified adapter and/or devices (add ":d,d,d" to specify list of SCSI IDs or ":(d,d),(d,d),(d,d)" to specify ID,LUN pairs). Default is enabled. /V Enable verbose mode (display configuration data during boot). Default is disabled. /RA Reorder adapters. This parameter is used to reverse the order in which the Fast!SCSI PCI Basic adapters are configured. This parameter is required on some systems with AMI BIOS and more than one Fast!SCSI PCI Basic adapters.
