Installation Instructions
=-=-=-=-=-=-=-=-=-=-=-=-=-=
Installing a New Driver or Updating an Existing Driver for OS/2 2.1X/Warp
-------------------------------------------------------------------------
1) Open the OS/2 System Folder, then open the System Setup folder.
2) If running OS/2 Warp 4.0, open the Install/Remove Folder.
3) Double-click on Device Driver Install.
4) Insert the Adaptec 7800 Family Manager Set 2.0 floppy in the
appropriate drive.
5) Change to the directory where the driver is located, usually \OS2.
6) When you find the driver (AIC7870.ADD), select INSTALL.
7) After the install finishes, select EXIT and reboot the computer.
You may also install the driver manually.
If running OS/2 2.1X, copy AIC7870.ADD to C:\OS2.
If running OS/2 Warp 3.x or 4.0, copy AIC7870.ADD to C:\OS2\BOOT.
Add a line to your CONFIG.SYS that says BASEDEV=AIC7870.ADD /V.
First-Time Installation of OS/2 2.1X/Warp From Floppy Diskette
--------------------------------------------------------------
(NOTE: To install the aic7870.add driver, it is necessary to copy the
driver from the Adaptec 7800 Family Manager Set v2.0 diskette for OS/2 on
to the OS/2 Diskette #1. However, before you can copy the driver, you must
first remove various files from the OS/2 Diskette #1, as explained in step 2
below.)
1) Make backup copies of the Installation Diskette and Disk #1.
2) Delete some of the existing files on the backup copy of the OS/2
diskette #1 so that approximately 140 KB of disk space is available
on the diskette. Use the following information to help you decide
which files to delete.
a) If the Adaptec 7800 Family host adapter is the only Adaptec host
adapter installed in your system, delete all other Adaptec drivers
(aha152x.add, aha154x.add, aha164x.add, aha174x.add, aic7770.add
and fd16_700.add).
b) If you have an Adaptec host adapter that is not part of the 7800
Family , delete all of the Adaptec drivers not used by that
particular host adapter. For example, if you have an Adaptec
AHA-1540CP host adapter installed in your computer, delete all
Adaptec drivers except for the aha154x.add driver.
c) If you have deleted the suggested Adaptec drivers above, and if you
do not have a Microchannel architecture system, and you still do not
have approximately 140 KB of disk space available on the diskette,
delete these files: ibm2flpy.add, ibm2adsk.add, and ibm2scsi.add.
(NOTE: If you have a combination PCI/Microchannel architecture system,
you need to delete third-party driver files not required.)
3) If you are installing OS/2 2.1X, use the backup copies of the
Installation Diskette and Disk #1 to do the following:
a) Copy OS2LDR from the Adaptec 7800 Family Manager Set v2.0 diskette
onto the Installation Diskette.
b) Copy IBMINT13.I13 from the Adaptec 7800 Family Manager Set v2.0
diskette onto Disk #1.
(NOTE: You do not need these files when installing OS/2 Warp.)
4) Add the following line to the config.sys file on OS/2 diskette #1:
BASEDEV=AIC7870.ADD
5) Install OS/2 using the backup diskettes and the remainder
of the standard OS/2 diskettes.
6) When installation has completed, reboot the system.
7) After the system has rebooted, follow the instructions for installing
the driver on a system containing OS/2.
First-Time Installation of OS/2 2.1X From CD-ROM
------------------------------------------------
(NOTE: To install the aic7870.add driver, it is necessary to copy the
driver from the Adaptec 7800 Family Manager Set v2.0 diskette for OS/2 on
to the OS/2 Diskette #1. However, before you can copy the driver, you must
first remove various files from the OS/2 Diskette #1, as explained in step 2
below.)
1) Use diskcopy to make backup copies of all IBM OS/2 and Adaptec
supplied diskettes. Use the backup copies as your working diskettes.
2) Delete some of the existing files on the backup copy of the OS/2
diskette #1 so that approximately 140 KB of disk space is available
on the diskette. Use the following information to help you decide
which files to delete.
a) If the Adaptec 7800 Family host adapter is the only Adaptec host
adapter installed in your system, delete all other Adaptec drivers
(aha152x.add, aha154x.add, aha164x.add, aha174x.add, aic7770.add
and fd16_700.add).
b) If you have an Adaptec host adapter that is not part of the 7800
Family, delete all of the Adaptec drivers not used by that
particular host adapter. For example, if you have an Adaptec
AHA-1540CP host adapter installed in your computer, delete all
Adaptec drivers except for the aha154x.add driver.
c) If you have deleted the suggested Adaptec drivers above, and if you
do not have a Microchannel architecture system, and you still do not
have approximately 140 KB of disk space available on the diskette,
delete these files: ibm2flpy.add, ibm2adsk.add, and ibm2scsi.add.
(NOTE: If you have a combination PCI/Microchannel architecture system,
you need to delete third-party driver files not required.)
3) Copy the OS2LDR file from the Adaptec 7800 Family Manager Set v2.0
diskette (i.e., \OS2\OS2LDR) onto the OS/2 installation diskette.
This overwrites the existing OS/2 loader on the diskette.
4) Copy the IBMINT13.I13 driver from the Adaptec 7800 Family Manager Set
v2.0 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.
5) Copy the AIC7870.ADD driver from the Adaptec 7800 Family Manager Set
v2.0 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.
6) Modify the CONFIG.SYS file on diskette #1 to include the following
line:
BASEDEV=AIC7870.ADD
7) Run the OS/2 installation program; follow the instructions in your
OS/2 documentation.
8) At the end of the installation process, follow the on screen 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:
a) If you installed OS/2 using the FAT Filesystem, boot up MS-DOS
to get to the command prompt.
b) 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. OS/2 should then
boot normally from the hard disk.
9) 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 on screen 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 8 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 8 above
to recover those files.)
First-Time Installation of OS/2 Warp 3.x or 4.0 From CD-ROM
-----------------------------------------------------------
(NOTE: To install the aic7870.add driver, it is necessary to copy the
driver from the Adaptec 7800 Family Manager Set v2.0 diskette for OS/2 on
to the OS/2 Diskette #1. However, before you can copy the driver, you must
first remove various files from the OS/2 Diskette #1, as explained in step 2
below.)
1) Use diskcopy to make backup copies of all IBM OS/2 and Adaptec supplied
diskettes. Use the backup copies as your working diskettes.
2) Delete some of the existing files on the backup copy of the OS/2
diskette #1 so that approximately 140 KB of disk space is available
on the diskette. Use the following information to help you decide
which files to delete.
a) If the Adaptec 7800 Family host adapter is the only Adaptec host
adapter installed in your system, delete all other Adaptec drivers
(aha152x.add, aha154x.add, aha164x.add, aha174x.add, aic7770.add
and fd16_700.add).
b) If you have an Adaptec host adapter that is not part of the 7800
Family, delete all of the Adaptec drivers not used by that
particular host adapter. For example, if you have an Adaptec
AHA-1540CP host adapter installed in your computer, delete all
Adaptec drivers except for the aha154x.add driver.
c) If you have deleted the suggested Adaptec drivers above, and if you
do not have a Microchannel architecture system, and you still do not
have approximately 140 KB of disk space available on the diskette,
delete these files: ibm2flpy.add, ibm2adsk.add, and ibm2scsi.add.
(NOTE: If you have a combination PCI/Microchannel architecture system,
you need to delete third-party driver files not required.)
3) Copy the aic7870.add driver from the Adaptec 7800 Family Manager Set
diskette for OS/2 (i.e., \os2\aic7870.add) onto the OS/2 installation
diskette #1. This overwrites any existing version of the driver
included on diskette #1.
4) For each driver removed from the OS/2 diskette #1, remove its
corresponding line in the config.sys file (also on OS/2 diskette #1).
For example, if you deleted all Adaptec drivers, as explained in step
2a, above, remove the following lines from config.sys:
basedev=aha152x.add
basedev=aha154x.add
basedev=aha164x.add
basedev=aha174x.add
basedev=aic7770.add
basedev=fd16_700.add
5) In the config.sys file on OS/2 diskette #1, add the line
"set copyfromfloppy=1".
This line should be added so that the install process copies the
aic7870.add driver from the OS/2 diskette #1, rather than the driver
included on your OS/2 CD-ROM.
(NOTE: For OS/2 Warp 4.0 users only, add "BASEDEV=aic7870.add" to the
top line of config.sys on OS/2 diskette #1. This will result in two
"BASEDEV=aic7870.add" statements in the config.sys file.)
6) Run the OS/2 installation program; follow the instructions in your
OS/2 documentation, until you reach the System Configuration window.
7) In the System Configuration window, click the SCSI Adapter Support
icon.
8) Deselect any highlighted adapters (including the Adaptec 294x, 394x,
AIC7870 PCI SCSI), and click OK. The text box for SCSI Adapter
Support should say "None".
(NOTE: If these adapters are not deselected, the driver included on
the CD-ROM will be copied over the driver being installed.)
9) Follow the instructions in your OS/2 documentation to complete the
installation.
(NOTE: The update files OS2LDR and IBMINT13.I13 included in the Adaptec
7800 Family Manager Set v2.0 are not needed when installing OS/2 Warp.)
(NOTE: Verify after installation is complete, that only one
"BASEDEV=aic7870.add" statement exists in your config.sys file on your hard
drive. Remove other instances if more than one is found.)

Known Issues
=-=-=-=-=-=-=
o 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:
1) Trouble installing OS/2 2.1X, and
2) 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.
o 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.
o The update files OS2LDR and IBMINT13.I13 included in the Adaptec 7800
Family Manager Set v2.0 are not needed when installing OS/2 Warp.
o This version of the Adaptec 7800 Family Manager Set v2.0 driver added
a new switch named /!PCIHW which enables the driver to skip accessing
the PCI hardware registers directly, and use PCI BIOS instead. This
switch could be useful for the users having problems loading the
AIC7870.ADD included with OS/2 Warp. Modify the CONFIG.SYS file to
include the following line:
BASEDEV=AIC7870.ADD /!PCIHW
o 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.
o 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.
=-=-=-=-=-=-=-=-=
Additional Notes
=-=-=-=-=-=-=-=-=
o This version of the Adaptec 7800 Family Manager Set v2.0 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 highest numbers, and the
adapters are assigned a number in the order they are found.
Example: Bus 0, device 0 assigned as adapter 0,
Bus 1, device 1 assigned as adapter 1, etc.
o 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.
o 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.
o 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!
o Fault Tolerance is supported in the driver. However, ABORT and SCSI
BUS RESET will only work for targets that are properly behaved.

Command Line Options
=-=-=-=-=-=-=-=-=-=-=
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.)
The standard format for command line switches is :
BASEDEV=AIC7870.ADD [Universal Parameter][Adapter ID][Unit Parameter]
{[SCSI Target ID]}
o [Universal Parameter] - An option that applies to all adapters
controlled by the driver.
o [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.)
o [Unit Parameter] - Modifies the behavior of the selected host adapter.
o [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:
---------------------
o /ET -- Allow embedded targets. This parameter indicates that the ADD
should assume that all targets have more than one logical unit (LUN)
defined.
o /!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.
o /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.
o /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
problems. This switch is enabled by default.
o /!PCIHW -- Disables the PCIHW switch. This parameter will cause the driver
to access the PCI configuration space through PCI BIOS function calls.
General Unit Parameters:
------------------------
o /I -- Ignore the specified adapter. This allows another driver to
share the adapters that the ADD would normally use.
o /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.
o /!DM -- Disable DASD manager support. This parameter prevents
OS2DASD.DMD from controlling the specified target(s).
o /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.
o /!SM -- Disable SCSI manager support. This parameter prevents
OS2SCSI.DMD from controlling the specified target(s).
o /TAG -- Specifies the maximum number of tagged commands for all target
devices on the host adapter (1-16). A value of 1 disables tagged
queuing. The maximum number allowed is 16. (The default is 8.)
o /UR -- Enables reporting of under runs (DEFAULT).
o /!UR -- Disables reporting of under runs.
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.
The following command line will prevent OS2DASD.DMD from accessing
the target and still allow OS2SCSI.DMD and OS2ASPI.DMD to share access
to it.
BASEDEV=AIC7870.ADD /A:0 /!DM:3
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.
The following command line 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.
BASEDEV=AIC7870.ADD /ET /A:0 /!SM:4 /A:1 /!DM:1,5
Special Unit Parameters:
------------------------
o /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.
o /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.
