IBM PS/2 SCSI-2 Fast/Wide Support Diskette Version 2.0 ------------------------------------------------------ INSTRUCTIONS FOR COPY OPTION To install this option you must boot the diskette and follow the directions of the installation programs. Failure to do so will prevent the proper files from getting updated on your system/diskette. If your system already comes equipped with a SCSI-2 Fast/Wide Controller then the required files came installed with your system unit. --------------------------------------------------------------------------- **************************************************************************** IMPORTANT INFORMATION FOR SYSTEMS WITH ENHANCED SCSI CONFIGURATION SUPPORT **************************************************************************** Some newer PS/2 Systems, such as the enhanced Server 95 models provide greater SCSI device and adapter configuration flexibility than previous systems. Systems with the enhanced SCSI device and adapter support allow up to 15 physical SCSI devices to be attached to an IBM SCSI-2 Fast/Wide adapter and up to 7 physical devices to be attached to the previous IBM PS/2 SCSI adapters. These newer systems also allow up to 8 IBM PS/2 SCSI adapters of any type to be installed in a single system. The maximum number of SCSI devices which many be configured in these newer systems has also been increased from 60 to 120. However, other factors, for example, the type of devices (optical, etc.), cooling requirements, or power consumption of the devices may limit the number for a particular system. Consult the particular system documentation for more information. Operating system support for the enhanced SCSI adapter and device configurations supported by these newer systems may vary depending on which particular operating system is being used. Newer levels of OS/2 and Novell Netware SCSI device drivers are included on this support diskette to take advantage of these new capabilities. SCSI device logical ordering and hard drive letter assignment (e.g. C:, D:) sequence is determined by the SCSI adapter slot numbers, internal or external SCSI bus connection, and SCSI ID of the connected devices. Adapters are scanned for SCSI devices beginning with the SCSI adapter in the lowest numbered slot. Devices connected to the same adapter are logically ordered according to device SCSI IDs in order from 7 to 0 and then from 15 to 8 according to the priority scheme defined by the SCSI standard. Devices connected to a SCSI-2 Fast/Wide adapter's internal bus connector are ordered logically before devices connected to the external bus of the same adapter. Wide SCSI devices support 16 possible SCSI ID values. The SCSI-2 Fast/Wide adapter uses one these values; therefore, the SCSI-2 Fast/Wide adapter can connect up to 15 fast and wide devices internally or externally in any combination using the remaining ID values. Narrow SCSI devices support 8 possible SCSI ID values; therefore, up to 7 narrow SCSI devices can be connected to the internal or external SCSI busses in any combination using the remaining ID values. Wide and narrow devices may be mixed on the same internal/external bus by using the proper combinations of SCSI bus cables, terminators, and/or SCSI connector convertor adapters. Older SCSI adapters supported only a single bus which provided both internal and external SCSI bus connectors for the single bus. For these adapters, devices are logically ordered depending only on adapter slot number and the SCSI IDs of the devices. Bootable CD ROM's are supported. Bootable read/write optical devices are supported if the device is jumpered to be configured as a removable hard disk. The media formatted and written to by this optical device cannot be read by a drive that is not jumpered to be bootable and vice-versa. Refer to the documentation for the device. Some newer systems also provide a FAST POST option which may be selected from the system configuration menu or from the IBM logo screen. When this option is selected, the system will not check for the presence of newly added SCSI devices unless F1 is also pressed while the IBM logo is displayed. Newly added SCSI devices will not be configured nor will an error occur if the fast post option is chosen as the default. To access the system configuration program, press F1 while the IBM logo screen is displayed to configure the new SCSI device(s) initially. The "Change Configuration" menu and the "Set and View SCSI Device Configuration" menus allow several methods of bypassing post error messages under various conditions if the user so desires. --------------------------------------------------------------------------- INSTRUCTIONS FOR DEVICE DRIVER INSTALLATION The following instructions are for installing the IBM* PS/2* SCSI-2 device drivers for OS/2* 2.0 or later and Novell** NetWare** Versions 3.11 and 4.0 or later. It is recommended that you print this README file prior to installing the files. ****************************************************** IMPORTANT INFORMATION FOR USERS OF OS/2 2.0 OR LATER ****************************************************** If you plan to use the SCSI-2 Fast/Wide adapter in a system which supports the enhanced SCSI configuration support as described above, you MUST use the version of the OS/2 2.X device driver (IBM2SCSI.ADD) on this diskette or a newer version. Before upgrading an older system to support the enhanced SCSI configuration support, the IBM2SCSI.ADD device driver from this diskette or a newer version must be copied to the OS2 subdirectory on the system hard disk containing OS/2. This may be done by using the DDINSTAL program from the OS/2 command prompt along with this diskette, or by manually copying the file. If an older version of the IBM2SCSI.ADD device driver is used with systems which support the enhanced SCSI configuration support, an OS/2 TRAP error may occur while the OS/2 operating system is loading. The DELIVERY.SYS device driver may also be added to the system's CONFIG.SYS file to enable the SCSI-2 tagged command queuing feature which provides improved SCSI subsystem performance in many cases. This driver will automatically be installed if the DDINSTAL program is used to install the device drivers. The OS/2 installation diskette 1 should also be updated with the latest IBM2SCSI.ADD so that OS/2 may be reinstalled at a later time. Copy the file to a copy of OS/2 installation diskette 1. ______________________________________________________ Installing SCSI-2 Device Drivers for OS/2 2.0 or Later ------------------------------------------------------ Use the instructions in this section if you have OS/2 2.0 or later already installed. Turn on the display and server. Put the support diskette in drive A. From any OS/2 full-screen session, type: DDINSTAL and press Enter. Select "IBM PS/2 SCSI-2 Fast/Wide Adapter Support Installation" from the menu and press Enter. This copies the SCSI-2 device drivers to your hard disk and adds these BASEDEV statements to your CONFIG.SYS file if the following statements are not there: BASEDEV=IBM2SCSI.ADD /LED BASEDEV=DELIVERY.SYS If your server had IBM SCSI-2 device drivers previously installed, and you added extra parameters to the above statement, you need to check your CONFIG.SYS file and ensure that it has only one BASEDEV statement for the IBM2SCSI.ADD. If you find two similar statements, you need to delete the extraneous statement from the CONFIG.SYS file, as follows: REM BASEDEV=IBM2SCSI.ADD /LED In addition, you should check for the presence of a BASEDEV statement for the IBM2M57.ADD device driver in the CONFIG.SYS file. If this statement is present, it should also be deleted or removed as follows: REM BASEDEV=IBM2M57.ADD _____________________________________________________________ Adding SCSI-2 Device Driver to the installation diskettes _____________________________________________________________ Make a copy of OS/2 Diskette 1. Copy the new IBM2SCSI.ADD from this support Diskette to the backup copy of OS/2 Diskette 1 . Edit the CONFIG.SYS file on the backup copy of OS/2 Diskette 1 and check for the presence of a BASEDEV statement for the IBM2M57.ADD device driver in the CONFIG.SYS file. If this statement is present, it should also be deleted or removed as follows: REM BASEDEV=IBM2M57.ADD The OS/2 installation diskette can now be used to boot and install OS/2 normally. After installation, use DDINSTAL to install the DELIVERY.SYS BASEDEV, or manually update the CONFIG.SYS file. ____________________________________________________________________ SCSI-2 Device Drivers during CD ROM installation ____________________________________________________________________ Make a copy of the OS/2 Diskette 1. Copy the new IBM2SCSI.ADD from this support diskette to the backup copy of OS/2 Diskette 1. Edit the CONFIG.SYS file on the backup copy of OS/2 Diskette 1 and check for the presence of a BASEDEV statement for the IBM2M57.ADD device driver in the CONFIG.SYS file. If this statement is present, it should also be deleted or removed as follows: REM BASEDEV=IBM2M57.ADD Install OS/2 using the CD-ROM installation procedure. When prompted to reboot the system, remove the OS/2 install diskette, press enter to begin the reboot operation, and then immediately re-insert the OS/2 install diskette. Insert the backup copy of Diskette 1 when prompted. When the Welcome to OS/2 screen appears press escape to exit to a command prompt. Copy IBM2SCSI.ADD from the OS/2 diskette 1 or from this diskette to the OS2 directory on the hard disk. Copy DELIVERY.SYS to the directory also. Remove the diskette and reboot the system without re-inserting the diskette. The OS/2 installation will continue. After installation, use DDINSTAL to install the DELIVERY.SYS BASEDEV, or manually add the following statement to the CONFIG.SYS file: BASEDEV=DELIVERY.SYS --------------------------------------------------------------------------- _______________________________________________________________________ Installing Device Drivers for Novell NetWare Versions 3.1X or 4.X ----------------------------------------------------------------------- Use the instructions in this section if you have Novell NetWare Version 3.1X or 4.X installed. The NetWare driver (PS2SCSIA.DSK) supports disks, CD-ROM drives, and the NetWare SBackup utility for tape backup support directly; therefore, TAPEDAI.DSK and CDNASPI.DSK should NOT be loaded. The driver does support an ASPI interface via the IBMASPI.NLM or IBMENTRY.NLM which has been tested with the following vendor tape backup software. The phone number for further information on each vendor product is provided below. Palindrome** - Network Archivist** (708-505-3300) Cheyenne** - ARCserv** (516-484-5110) NOTE: Tape drives which do not support 4K block sizes will result in a warning message that they must use ASPI tape backup software. 1. Turn on the display and system unit. 2. Prepare the NetWare startup drive according to the instructions in the NetWare manual. 3. Insert the IBM PS/2 SCSI-2 Fast/Wide Adapter Support Diskette which contains the PS2SCSIA.DSK driver and other files required for Netware support into the diskette drive. 4. Type the following: copy a:\PS2SCSIA.DSK d: (where d: is the NetWare startup drive) and press Enter. The PS2SCSIA.DSK driver is the base device driver for the IBM PS/2 SCSI-2 FAST/WIDE Adapter which supports hard disks, IBM CD-ROM drives, IBM tape drives, and IBM Rewritable Optical Disk drives. Additional Netware Loadable Modules (NLMs) described below are also provided to support Netware ASPI compliant device drivers required by SCSI device drivers and Netware compatible server backup software packages. 5. Type the following: copy a:\IBMASPI.NLM d: (where d: is the NetWare startup drive) and press Enter. The IBMASPI.NLM exports the "ASPI_Entry" entry point and sends IOCTL commands to the IBMPSCSI.DSK module. These two modules are usually all that is required for both disk and ASPI support. 6. Type the following: copy a:\SCSISCAN.NLM d: (where d: is the NetWare startup drive) and press Enter. Use of this module is optional and is provided to aid in verifying that the customer has successfully installed the PS2SCSIA.DSK, IBMASPI.NLM, IBM PS/2 SCSI-2 Fast/Wide adapter and devices. Successful execution of this NLM will result in a screen display showing all attached SCSI devices and their ID's. It is recommended that this NLM be run prior to installing tape backup software. NOTE: Currently the SCSISCAN.NLM module will only scan for up to 7 devices per SCSI adapter. However, the PS2SCSIA.DSK driver on this diskette does support up 15 SCSI devices per adapter as allowed by systems with the enhanced SCSI configuration support. 7. Type the following: copy a:\IBMENTRY.NLM d: (where d: is the NetWare startup drive) and press Enter. Use of the IBMENTRY.NLM file is optional and is provided for systems which already have another vendor's SCSI adapter configured to use the exported "ASPI_Entry" entry point. The export name of "IBM_Entry" is provided to ASPI device drivers as an alternate entry point in this situation. 8a. If you are using Netware version 3.12, the following system patches also must be copied. Type the following: copy a:\nw312\DAICCFIX.NLM d: (where d: is the NetWare startup drive) and press Enter. Type the following: copy a:\nw312\REALMFIX.NLM d: (where d: is the NetWare startup drive) and press Enter. Type the following: copy a:\nw312\PM312.NLM d: (where d: is the NetWare startup drive) and press Enter. 8b. If you are using Netware version 4.xx, the following system patches also must be copied. Type the following: copy a:\nw4xx\DAICCFIX.NLM d: (where d: is the NetWare startup drive) and press Enter. Type the following: copy a:\nw4xx\REALMFIX.NLM d: (where d: is the NetWare startup drive) and press Enter. Type the following: copy a:\nw4xx\PM401.NLM d: (where d: is the NetWare startup drive) and press Enter. 9. If you are using Cheyenne ARCserve server backup software for DOS Version 4.0 or for Windows Version 5.0 or earlier, you must also install the following new version of ASPI50.NLM. Type the following: copy a:\ASPI50.NLM d: (where d: is the NetWare startup drive) and press Enter. 10. To start the NetWare operating system, type the following at the command prompt: SERVER and press Enter. 11. At this time, make sure all activity on the server has stopped. Then load the DAICCFIX.NLM and REALMFIX.NLM NetWare patch files in that order if they were copied in step 8a or 8b above and you are using Netware version 3.12 or 4.xx. NOTE: The PM312.NLM or PM401.NLM patch files will be loaded automatically. 12. At the NetWare server console prompt, type the following: LOAD d:PS2SCSIA (where d: is the NetWare startup drive) and press Enter. This loads the basic device driver required for Netware support. The appropriate NLMs that you chose to copy above should also be loaded at this time depending on your version of Netware and other installed equipment/software. In summary a customer should first load PS2SCSIA.DSK then IBMASPI.NLM. Finally it is recommended that a customer load SCSISCAN.NLM which will do an SCSI scan of the bus using the ASPI interface to verify that the SCSI adapter, SCSI devices, NLM and DSK are loaded and operating properly. Any problems up to this point should be directed to IBM customer support. NOTE: Before creating or deleting NetWare disk partitions with the NetWare INSTALL.NLM utility while running NetWare 3.12 or 4.xx, the IBMASPI.NLM and/or IBMENTRY.NLM must be unloaded. -------------------------------------------------------------------------------- __________ TRADEMARKS ---------- The following terms, denoted by an asterisk (*) in this file, are trademarks of the IBM Corporation in the United States or other countries: IBM PS/2 OS/2 The following terms, denoted by a double asterisk (**) in this file, are trademarks of other companies as follows: Novell Novell, Inc.
