If you are performing a first time Windows 95 installation, see Installing Windows 95 and the Driver. If Windows 95 is already installed in your system, see Updating Windows 95 with the Driver. NOTE: When Windows 95 starts, if a "New Hardware Found" dialog is displayed after installing your 7800 Family host adapter, please select "Driver from disk provided by hardware manufacturer." Then insert your 7800 Family Manager Set Diskette and type A:\win95 as the path. Follow the succeeding on-screen instructions. Installing Windows 95 and the Driver ==================================== A version of the aic78xx.mpd driver is embedded (included) in the Windows 95 installation CD. This driver does NOT support the FAST20 line of PCI SCSI host adapters, such as the AHA-2940U, AHA-2940UW, AHA-2940AU, AHA-3940U etc. If you have a member of the FAST20 line of PCI SCSI host adapters, you must follow the instructions listed under Updating Windows 95 with the Driver, below. Other (non-FAST20) members of the 7800 Family of host adapters are detected in your system and the embedded aic78xx.mpd driver is automatically installed. Once the Windows 95 installation is complete, you can update the aic78xx.mpd driver with the most recent version of the driver by following the instructions in Updating Windows 95 with the Driver, below. NOTE: When Windows 95 starts, if a "New Hardware Found" dialog is displayed after installing your 7800 Family host adapter, please select "Driver from disk provided by hardware manufacturer." Then insert your 7800 Family Manager Set Diskette and type A:\win95 as the path. Follow the succeeding on-screen instructions. Updating Windows 95 with the Driver ==================================== This section describes how to update/install the aic78xx.mpd driver if Windows 95 is already installed. If you are installing Windows 95 for the first time, see Installing Windows 95 and the Driver, above. Note: All Adaptec 7800 Family host adapters use the same aic78xx.mpd driver. Once the driver is updated, it is not necessary to update it again for each 7800 Family host adapter installed in your system. 1 Start Windows 95. 2 Click the Start button on the Windows 95 task bar, and then point to Settings. 3 Click Control Panel. 4 Double-click the System icon. 5 On the Device Manager tab, double-click on the SCSI Controllers icon. NOTE: If your adapter is not listed, there is no SCSI Controllers icon, or there is an Other Devices icon under the Device Manager, double-click on the Other Devices icon. If you see something similar to "PCI SCSI Bus Controller" listed, you must update the driver for this device. Continue with step 6. 6 Double-click the 7800 Family host adapter you wish to update, or if a yellow question mark labeled "PCI SCSI Bus Controller" is displayed under the Other Devices icon, double-click on the question mark. 7 On the Driver tab, click Change Driver. You may be asked to select the hardware type; if asked to do so, select SCSI Controller. 8 Click the Have Disk button and enter a:\win95 as the location to copy the manufacturer's file from. 9 Click OK. 10 Select your 7800 Family host adapter, and click OK. 11 Click OK. The driver is copied and scanned. 12 You must restart your computer for the changes to take effect. Click Yes to restart your computer. Click No to return to the system properties window. NOTE: When Windows 95 starts, if a "New Hardware Found" dialog is displayed after installing your 7800 Family host adapter, please select "Driver from disk provided by hardware manufacturer." Then insert your 7800 Family Manager Set Diskette and type A:\win95 as the path. Follow the succeeding on-screen instructions. Fast20 Host Adapters ==================== A version of the aic78xx.mpd driver is embedded (included) in the Windows 95 installation CD. This driver does NOT support Fast20 Host Adapters such as the AHA-2940AU, AHA-3940U, AHA-3940UW, etc. When Windows 95 cannot determine the type of host adapter installed in your computer, a yellow question mark labeled Other Devices appears instead of the SCSI controller icon. You must update each adapter listed under Other Devices. See Updating Windows 95 with the Driver, above, for each yellow question mark labeled under Other Devices. To make sure your 7800 Family Manager Set drivers are properly installed and operating under Windows 95, please do the following: 1 Open the Control Panel, double-click on System, and click on the Device Manager tab. 2 Double-click on the SCSI Controllers icon; you should see your 7800 Family Manager Host Adapter listed. 3 If your adapter is not listed, there is no SCSI Controllers icon, or there is an Other Devices icon under the Device Manager, double-click on the Other Devices icon. If you see something similar to "PCI SCSI Bus Controller" listed, you must update the driver for this device. Follow the instructions listed under Updating Windows 95 with the Driver. 4 If there is a yellow exclamation point or red X in front of the 7800 Family Manager Host Adapter, double-click on the icon to see the error message. Note: Due to an inherent Windows 95 bug, each channel of the AHA-3940U and AHA-3940UW must be updated/installed manually with the aic78xx.mpd driver on a freshly installed Windows 95 system. Please follow the instructions listed under Updating Windows 95 with the Driver.

This includes: AHA-2910 PCI-to-Fast SCSI (non-bootable) AHA-2940 PCI-to-Fast SCSI AHA-2940W PCI-to-Fast and Wide Single-Ended SCSI AHA-2944W PCI-to-Fast and Wide Differential SCSI AHA-2940Ultra PCI-to-Wide UltraSCSI AHA-3940 MultiChannel PCI-to-Fast SCSI AHA-3940W MultiChannel PCI-to-Fast and Wide SCSI AIC-7850 Single-Chip PCI-to-Fast SCSI AIC-7870 Single-Chip PCI-to-Fast and Wide SCSI AIC-7880 Single-Chip PCI-to-UltraSCSI The folowing files on this diskette are required for the installation of the 7800 Family OS/2 driver: \os2\aic7870.add \os2\7870pres.exe \os2\aic7870.ddp ============================================================================= INSTALLATION INSTRUCTIONS FOR THE OS/2 DRIVER: ============================================================================= 1) Installing a New Driver or Updating an Existing Driver for OS/2 2.1X/Warp ---------------------------------------------------------------------------- a) Open the OS/2 System Folder, then open the System Setup folder. b) Double-click on Device Driver Install. c) Insert the Manager Set floppy in the appropriate drive. d) Change to the directory where the driver is located, usually \OS2. e) When you find the driver (AIC7870.ADD), select INSTALL. f) After the install finishes, a message will appear to report the status. An error will be displayed if no host adapters are found. You may also install the driver manually. If running OS/2 2.1X, copy AIC7870.ADD to C:\OS2. If running OS/2 Warp, copy AIC7870.ADD to C:\OS2\BOOT. Add a line to your CONFIG.SYS that says BASEDEV=AIC7870.ADD . Note: If you run out of disk space and are unable to copy the AIC7870.ADD driver to the appropriate directory, you will need to delete other drivers in that directory that are not being used. Be sure to make backup copies of any drivers or files before deleting them. 2) First-Time Installation of OS/2 2.1X/Warp From Floppy Diskette ----------------------------------------------------------------- a) Make backup copies of the Installation Diskette and Disk #1. b) If you are installing OS/2 2.1X, use the backup copies of the Installation Diskette and Disk #1 to do the following: 1) Copy OS2LDR from the 7800 Manager Set onto the Installation Diskette. 2) Copy IBMINT13.I13 from the 7800 Manager Set onto Disk #1. Note: You do not need these files when installing OS/2 Warp. c) Install OS/2 using the backup diskettes and the remainder of the standard OS/2 diskettes. d) When installation has completed, reboot the system. e) After the system has rebooted, follow the instructions for installing the driver on a system containing OS/2. 3) First-Time Installation of OS/2 2.1X From CD-ROM --------------------------------------------------- a) Use diskcopy to make backup copies of all IBM OS/2 and Adaptec supplied diskettes. Use the backup copies as your working diskettes. b) Copy the OS2LDR file from the 7800 Family Manager set diskette (i.e., \OS2\OS2LDR) onto the OS/2 installation diskette. This overwrites the existing OS/2 loader on the diskette. c) Copy the IBMINT13.I13 driver from the 7800 Family Manager set diskette (i.e.,\OS2\IBMINT13.I13) onto the OS/2 installation diskette #1. This overwrites any existing version of the driver included on diskette #1. d) Copy the AIC7870.ADD driver from the 7800 Family Manager set diskette (i.e., \OS2\AIC7870.ADD) onto the OS/2 installation diskette #1. This overwrites any existing version of the driver included on diskette #1. e) Modify the CONFIG.SYS file on diskette #1 to include the following line: BASEDEV=AIC7870.ADD /PCIHW f) Run the OS/2 installation program; follow the instructions in your OS/2 documentation. g) At the end of the installation process, follow the onscreen instructions to remove the last OS/2 distribution diskette and reboot the computer. If the computer fails to boot up, and locks up while displaying the OS/2 logo screen, you may use one of the following options to get to the command prompt: 1) If you installed OS/2 using the FAT Filesystem, boot up MS-DOS to get to the command prompt. 2) If you installed OS/2 using the HPFS Filesystem, insert the Installation Diskette and boot up the computer from this diskette. When the IBM screen is displayed, remove the Installation diskette and insert Diskette #1 as instructed to do so. After a while, a screen will be displayed asking which installation method you wish to choose. At this point, press the F3 key to get to the command prompt. Once you get to the command prompt, change to the drive where the OS/2 system files are located (usually Drive C:). You may now use a text editor to again modify the OS/2 CONFIG.SYS file on the hard drive to add the /PCIHW switch to the BASEDEV=AIC7870.ADD line as shown in step e. OS/2 should then boot normally from the hard disk. h) After the computer has restarted, OS/2 displays a screen. You have the option to view online information while the OS/2 desktop is building. Allow OS/2 to finish building, and follow the onscreen instructions to restart the computer. Again, if the computer fails to boot up, and locks up while displaying the OS/2 logo screen, repeat the process specified in step g to correct the problem. Note: The CONFIG.SYS, IBMINT13.I13, and OS2LDR files may be overwritten by equivalent files from the CD-ROM. If this occurs, follow step g above to recover those files. 4) First-Time Installation of OS/2 Warp From CD-ROM --------------------------------------------------- a) Use diskcopy to make backup copies of all IBM OS/2 and Adaptec supplied diskettes. Use the backup copies as your working diskettes. b) Run the OS/2 installation program; follow the instructions in your OS/2 documentation. After reboot, update the AIC7870.ADD on the boot drive from DISK #1 (this file will be overwritten from the CD-ROM). NOTE: The update files OS2LDR and IBMINT13.I13 included in the 7800 Family Manager Set are not needed when installing OS/2 Warp. Additional Notes: ----------------- OS/2 2.1X currently does not identify PCI systems and handles them in the same way it would an ISA system. This can cause several different problems: trouble installing OS/2 2.1X and an inability to share a single interrupt between multiple PCI adapters. IBM is aware of these problems and has open APARs (PJ14230 and PJ14710) tracking them. They will be fixed in a future release of OS/2; please check the list of closed APARs accompanying each future release. Currently, we have files which can be used as interim fixes for both these problems: OS2LDR - A new PCI aware version of the loader. This file can be used during installation or installed after the installation of OS/2 has completed. IBMINT13.I13 - A new PCI aware version of the generic INT 13H driver that is used during installation from floppy disk. If you update Disk #1 of the CD-ROM installation to include OS2LDR, please be aware that this file will be overwritten from the CD-ROM. It may have to be updated again on the boot drive when the installation has completed. The update files OS2LDR and IBMINT13.I13 included in the 7800 Family Manager Set are not needed when installing OS/2 Warp. This driver added a new switch named /PCIHW which enables the driver to ignore the PCI BIOS and access the PCI hardware registers directly. This switch could be useful for the users having problems loading the AIC7870.ADD included with OS/2 Warp, if their system has a non-compliant system BIOS. BASEDEV=AIC7870.ADD /PCIHW Intel Errata #8511 lists known data integrity issues with the processor cache on the Saturn-1 chipset (82424TX). For this reason Adaptec recommends that processor cache be disabled via the CMOS setup to avoid data corruption. For more information, see Intel Errata #8511. You may get this from Intel's FaxBack system at 800.628.2283 or 916.356.3105. For more detailed information see Errata #8512 and 8513. There is currently no support for installing OS/2 2.0 on a hard drive attached to an AIC-7870, due to limitations in the installation procedure. Upgrading to OS/2 2.1 or higher is recommended. ============================================================================= Configuration Information: ============================================================================= Generic Command Line Switches for Adaptec Drivers and OS/2 2.1X and Above ------------------------------------------------------------------------- OS/2 adapter device drivers (.ADD files) are normally installed automatically and require no further information from the user. However, in certain situations the user may wish to modify the behavior of the driver to meet their specific needs. ***** IMPORTANT ***** Please proceed cautiously with the following information. If you have purchased software which requires you to use switches, it should include instructions on how to use them. Most software requires no switches and you do not need to concern yourself with the information about switch settings. The standard format for command line switches is : BASEDEV=AIC7870.ADD [Universal Parameter][Adapter ID][Unit Parameter] {[SCSI Target ID]} [Universal Parameter] - An option that applies to all adapters controlled by the driver. [Adapter ID] - /A:n, where n is the number (zero relative) of the adapter installed in the system. The adapter ID is determined when the driver is loaded based on the order that adapters are found in the system. (See below, AIC7870.ADD Specific Command Line Switches.) [Unit Parameter] - Modifies the behavior of the selected host adapter. [SCSI Target ID] - The targets to which the Unit Parameter will be applied. This parameter may be a single ID (d) or list of IDs (d,d,d). Universal Parameters: --------------------- /ET - Allow embedded targets. This parameter indicates that the ADD should assume that all targets have more than one logical unit (LUN) defined. /!ET - Do not allow embedded targets (DEFAULT). This parameter indicates that the ADD should assume that all targets have only one logical unit (LUN) defined. /V - Load driver verbosely. This parameter will display the driver name as well as the version number and Adaptec copyright if the driver loads successfully. Information on all targets found in the system will also be displayed. /PCIHW Enables driver to access PCI configuration hardware registers. This switch is implemented because in some PCI systems accessing PCI configuration space through PCI BIOS function calls causes problem. /INSTR Enables I/O Performance monitoring. This switch allows the AIC7870.ADD driver to record I/O statistics and errors. General Unit Parameters: ------------------------ /I - Ignore the specified adapter. This allows another driver to share the adapters that the ADD would normally use. /DM - Enable DASD manager support (DEFAULT). This parameter allows OS2DASD.DMD to control the specified target(s) if they are identified as DASD (hard disk) devices. /!DM - Disable DASD manager support. This parameter prevents OS2DASD.DMD from controlling the specified target(s). /SM - Enable SCSI manager support (DEFAULT). This parameter allows OS2SCSI.DMD to control the specified target(s) if they are identified as NON-DASD SCSI devices. All SCSI hard drives will be controlled by OS2DASD.DMD. /!SM - Disable SCSI manager support. This parameter prevents OS2SCSI.DMD from controlling the specified target(s). Configuration Examples: ----------------------- Example 1 Suppose that you had a removable hard drive as target 3 and you wanted to control the hard drive with an ASPI application and driver. Normally OS2DASD will allocate this device, treat it as a large floppy and prevent you from sending any SCSI commands via ASPI. BASEDEV=AIC7870.ADD /A:0 /!DM:3 will prevent OS2DASD.DMD from accessing the target and still allow OS2SCSI.DMD and OS2ASPI.DMD to share access to it. Example 2 Suppose that you had a multi-disk CD-ROM as target 4 on host adapter 0 and two DASD devices as targets 1 and 5 on host adapter 1. BASEDEV=AIC7870.ADD /ET /A:0 /!SM:4 /A:1 /!DM:1,5 will prevent OS2SCSI.DMD from accessing the CD-ROM and prevent OS2DASD.DMD from controlling the DASD devices. The driver will also search for multiple LUNs on all host adapters. Important Tips: --------------- 1) There are no switches for controlling OS2ASPI.DMD directly. IBM did not define them in their specification and we cannot be sure that other host adapters will have the same switches. 2) OS2SCSI.DMD will only allocate devices when a device driver requests it, but this will prevent OS2ASPI from accessing it. There is nothing in the ASPI specification regarding device allocation so OS2ASPI must rely on other managers to fairly share targets. This should only be a problem if you have two drivers that use different managers and you want them both to access the same target at the same time. 3) Do NOT disable DASD manager access to target 0 if you are booting from your SCSI host adapter. This will prevent the system from booting! AIC7870.ADD-Specific Command Line Switches ------------------------------------------ This driver supports the AIC-7800 Family of Host Adapters. Adapter numbers are first assigned to boards with their BIOS enabled. The numbers are assigned from lowest BIOS address to highest address. Any remaining boards are assigned numbers by scanning slots. Each slot is a combination of a bus number and a device number pair starting from lowest to higest numbers, and the adapters are assigned a number in the order they are found. Special Unit Parameters: ------------------------ /TAG: - Sets the number (1-16) of tagged commands for all target devices on the host adapter. A value of one disables tagged queuing. 16 is the maximum number allowed and 8 is the default value. /TAG:1 Disables tagged queuing for all target devices on a given host adapter. The driver maintains a maximum of 2 non- tagged commands per target internally. The driver treats all target devices as non-tagged devices, and sends only one command at a time per target to the host adapter. Example: BASEDEV=AIC7870.ADD /A:0 /TAG:8 will set the number of tagged commands for all target devices on the first host adapter to 8. ============================================================================== Limitations: ============================================================================== Fault Tolerance is now supported in the driver. However, ABORT and SCSI BUS RESET will only work for targets that are properly behaved. ############################################################################ (4) Adaptec 7800 Family Managers for NetWare 3.1X and 4.XX ====================================================== This disk contains Adaptec's Novell solution for the AIC-7800 Family of Host Adapters. This includes AHA-2940s (PCI to SCSI), AHA-2940Ws (PCI to SCSI with wide channel), AHA-2944Ws (PCI to Wide Differential SCSI), AHA-3940 (PCI MultiChannel SCSI), AHA-3940Ws (PCI MultiChannel Wide SCSI), AHA-2910 (PCI to SCSI without BIOS), AIC-7870 (Chip on the motherboard supporting wide channel), AIC-7850 (Chip on the motherboard supporting 8-bit SCSI channel). Manager Set 1.2 begins support for Adaptec's new line of double-speed PCI to SCSI products: AIC-7880 (Chip on the motherboard), and AHA-2940UltraWide (PCI to Wide SCSI board). NOTE: To use CD-ROM's in conjunction with these drivers, EZ-SCSI version 3.03 or above must be installed. The files included on this diskette which are required for the installation of the NetWare drivers are as follows: \netware\v3_1x\aic7870.dsk \netware\v3_1x\aspitran.dsk \netware\v3_1x\aspicd.dsk \netware\v4_xx\aic7870.dsk \netware\v4_xx\aic7870.ddi \netware\v4_xx\aspitran.dsk \netware\v4_xx\aspicd.dsk \netware\v4_xx\aspicd.ddi If required, please consult your DOS manual on how to move around the directory tree. Within a subdirectory, you will find a README.TXT file describing the driver(s) contained in that subdirectory. This disk provides the following NetWare drivers: ----------------------------------------------------------------------------- 1.) AIC-7870 Family of Host Adapters Driver For NetWare 386 v3.1x. (\netware\v3_1x) ----------------------------------------------------------------------------- 2.) AIC-7870 Family of Host Adapters Driver For NetWare 386 v4.xx. (\netware\v4_xx) ----------------------------------------------------------------------------- 3.) ASPITRAN.DSK ASPI Transport Layer Manager Driver for NetWare v3.1x and v4.xx. (\netware\v3_1x) or (\netware\v4_xx) ----------------------------------------------------------------------------- 4.) AIC7870.DDI Driver definition information file for NetWare v4.xx only. (\netware\v4_xx) ----------------------------------------------------------------------------- 5.) ASPICD.DSK CD-ROM Driver for NetWare v3.1x and v4.xx. (\netware\v3_1x) or (.\netware\v4_xx) ----------------------------------------------------------------------------- 6.) ASPICD.DDI CD-ROM Driver definition information file for NetWare v4.xx only. (.\netware\v4_xx) ----------------------------------------------------------------------------- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Problem with DDI file for Netware 4.0X -------------------------------------- There is a known problem which occurs during the installation of Netware 4.0X. This problem involves the DDI file used during the initialization of the host adapter device driver. The problem is that the DDI does not contain all the possible slot number options available on all PCI systems, as there are too many combinations. As a result, during the installation procedure, NetWare will report that it was unable to load the driver in the given amount of time. The cause of this is because the DDI file does not contain any slot options, which causes NetWare to be unable to load the driver. Note, however, that this is not an error. The user simply needs to go to the console screen and manually enter in the correct slot number and installation will continue. Problem with Quantum Empire 540S drives --------------------------------------- A second known problem exists that will hang the server after loading the host adapter device driver. This problem involves targets that do not support scanning of multiple luns, with the command line option lun_enable. The user simply needs to set the command line option multlun_targets to only scan targets that support multiple luns. This problem is known to occur with Quantum Empire 540S drives.
