Changes From Prior Release
=-=-=-=-=-=-=-=-=-=-=-=-=-
Adaptec 7800 Family Manager Set v3.02 features enhancements from the
previous v3.01 version. These features include:
o Support for a wider variety of Ultra2SCSI PCI IC's and host adapters.
=-=-=-=-=-=-=-=-=-=-=-=-=
Installation Instructions
=-=-=-=-=-=-=-=-=-=-=-=-=
The AIC78U2.ADD Ultra2SCSI driver only supports OS/2 Warp 3.x, 4.0 and 4.0
Server. The AIC7870.ADD UltraSCSI or earlier driver also supports OS/2 version
2.1x in addition to versions 3.x, 4.0 and 4.0 Server.
Installing a New Driver or Updating an Existing Driver
for OS/2 2.1X/Warp/Server
------------------------------------------------------
(NOTE: When installing a new host adapter, make sure it is inserted in the
system before installing the driver.)
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 v3.02 floppy in the
appropriate drive.
5) Change to the directory where the driver is located.
a) For Ultra2SCSI host adapters, the driver will be located in
\OS2\AIC78U2 (for OS/2 Warp or Server only)
b) For UltraSCSI or earlier host adapters, the driver will be located in
\OS2\AIC7870
6) a) For Ultra2SCSI host adapters,
When you find the driver (AIC78U2.ADD), select INSTALL.
b) For UltraSCSI or earlier host adapters,
When you find the driver (AIC7870.ADD), select INSTALL.
7) After the installation finishes, be sure to check the C:\ directory and
delete any previous versions of the AIC78U2.ADD and/or AIC7870.ADD drivers
before rebooting the system. If you do not remove those drivers, OS/2
will load them instead of the new drivers that you have just installed.
8) Select EXIT and reboot the computer.
You may also install the driver manually.
For Ultra2SCSI host adapters:
Copy AIC78U2.ADD to C:\OS2\BOOT.
Add a line to your CONFIG.SYS that says BASEDEV=AIC78U2.ADD /V.
For UltraSCSI or earlier host adapters:
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/Server From Floppy Diskette
---------------------------------------------------------------------
(NOTE: To install the driver, it is necessary to copy the driver from
the Adaptec 7800 Family Manager Set v3.02 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 Diskette 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, aic7870.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 you
still do not have approximately 140 KB of disk space available on
the diskette, delete the file: CDINST.EXE (for OS/2 Warp or Server
only).
3) If you are installing OS/2 2.1X, use the backup copies of the
Installation Diskette and Diskette 1 to do the following:
a) Copy OS2LDR from the Adaptec 7800 Family Manager Set v3.02
diskette onto the OS/2 Installation Diskette.
b) Copy IBMINT13.I13 from the Adaptec 7800 Family Manager Set v3.02
diskette onto the OS/2 Diskette 1.
(NOTE: You do not need these files when installing OS/2 Warp or
Server)
4) Add the following lines to the config.sys file on OS/2 Diskette 1:
a) For Ultra2SCSI host adapters:
BASEDEV=AIC78U2.ADD
Set CopyFromFloppy=1
b) For UltraSCSI or earlier host adapters:
BASEDEV=AIC7870.ADD
Set CopyFromFloppy=1
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.
First-Time Installation of OS/2 2.1X From CD-ROM
------------------------------------------------
Only the AIC7870.ADD driver is supported under OS/2 2.1X . The Ultra2SCSI
AIC78U2.ADD driver is not supported under OS/2 2.1X.
(NOTE: To install the AIC7870.ADD driver, it is necessary to copy the
driver from the Adaptec 7800 Family Manager Set v3.02 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.
3) Copy the OS2LDR file from the Adaptec 7800 Family Manager Set v3.02
diskette (i.e., \OS2\AIC7870\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
v3.02 diskette (i.e.,\OS2\AIC7870\IBMINT13.I13) onto the OS/2
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
v3.02 diskette (i.e., \OS2\AIC7870\AIC7870.ADD) onto the OS/2
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, 4.0 or 4.0 Server From CD-ROM
-----------------------------------------------------------------------
(NOTE: To install the driver, it is necessary to copy the driver from
the Adaptec 7800 Family Manager Set v3.02 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) Type CDINST from CD-ROM drive to create the boot diskettes from OS/2
CD.
2) Delete some of the existing files on 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).
(NOTE: If you are installing the Ultra2SCSI host adapter, delete
the AIC7870.add driver as well.)
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 you
still do not have approximately 140 KB of disk space available on
the diskette, delete the file: CDINST.EXE.
***************************************************************
Note: The following files MUST NOT BE DELETED from Diskette 1:
CLOCK01.SYS
CLOCK02.SYS
IBM1S506.ADD
IBM1FLPY.ADD
IBM2FLPY.ADD
IBM2ADSK.ADD
IBM2SCSI.ADD
IBMINT13.I13
IBMKBD.SYS
KBDBASE.SYS
OS2LOGO
OS2DASD.DMD
PNP.SYS
RESERVE.SYS
RESOURCE.SYS
SCREEN01.SYS
SCREEN02.SYS
XDFLOPPY.FLT
*.SNP (all files with the extension of SNP)
****************************************************************
3) Copy the driver from the Adaptec 7800 Family Manager Set diskette for
OS/2 onto the OS/2 Diskette 1.
a) For Ultra2SCSI host adapters, the driver (AIC78U2.ADD) will be
located in \OS2\AIC78U2 directory.
b) For UltraSCSI or earlier host adapters, the driver (AIC7870.ADD)
will be located in \OS2\AIC7870 directory.
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:
rem basedev=aha152x.add
rem basedev=aha154x.add
rem basedev=aha164x.add
rem basedev=aha174x.add
rem basedev=aic7770.add
rem basedev=fd16-700.add
(NOTE: If you are installing the Ultra2SCSI host adapter, then
remove the basedev=aic7870.add statement as well.)
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
AIC78U2.ADD or AIC7870.ADD driver from the OS/2 Diskette 1, rather
than the driver included on the OS/2 CD-ROM.
(NOTE: a. For Ultra2SCSI host adapters, Add "BASEDEV=aic78U2.add" to
the top line of config.sys on OS/2 Diskette 1. This may result in
two "BASEDEV=aic78U2.add" statements in the config.sys file.
b. For UltraSCSI or earlier host adapters, 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: After installation is complete, verify that only one
"BASEDEV=aic78U2.add" or "BASEDEV=aic7870.add" statement exists in your
config.sys file on your hard drive. Remove other instances if more than
one is found.)
NOTE: There is also another procedure posted on the IBM web site that
does not require the "SET COPYFROMFLOPPY=1" flag in CONFIG.SYS.

Known Issues
=-=-=-=-=-=-
o This version of the Adaptec 7800 Family Manager Set v3.02 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 users having problems loading the driver
included with OS/2 Warp or Server. Modify the CONFIG.SYS file to include
the following line:
a. For Ultra2SCSI host adapters:
BASEDEV=AIC78U2.ADD /!PCIHW
b. For UltraSCSI or earlier host adapters:
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.
o There are installation problems when installing on the maximum hard
disk drive partition size supported by OS/2 v3.0. On OS/2 v3.0 it is
a known problem. Refer to IBM for further info. IBM's APARs PJ15988
and PJ 6151 deal with this issue.
o There are known installation problems installing OS/2 Warp v4.0 on a
Micron (LSI chipset) 64 bit PCI system.
o There are known installation problems installing OS/2 Warp with 8MB
of RAM unless all the third-party basedev statements are removed from
config.sys.
o There are known installation problems installing OS/2 using two SCSI
host adapters on Marl mother board.
o Whenever you have a LVD HDD on one Ultra2SCSI host adapter and a HDD,
CD-ROM, and removable Syjet on another UltraSCSI host adapter, Syjet
conflicts with the CD-ROM and the system is unable to access the
CD-ROM.
=-=-=-=-=-=-=-=-
Additional Notes
=-=-=-=-=-=-=-=-
o This version of the Adaptec 7800 Family Manager Set v3.02 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 On some PCI systems, users may sometimes have problems loading the
driver when the host adapter board is seated in a particular slot.
Moving the host adapter board to another slot may solve the problem. If
the problem still persists, it may be occurring because the Adaptec 7800
Family Manager Set v3.02 driver is unable to access the PCI hardware
registers directly. To overcome this, users should use the /!PCIHW
switch. Modify the CONFIG.SYS file to include the following line:
a. For Ultra2SCSI host adapters:
BASEDEV=AIC78U2.ADD /!PCIHW
b. For UltraSCSI or earlier host adapters:
BASEDEV=AIC7870.ADD /!PCIHW
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.
o IBM does not support installing the operating system onto magneto optical
devices. Additionally, OPTICAL.SYS (OS/2 V3.0) or OPTICAL.DMD (OS/2 V4.0)
allows magneto optical devices to be supported as though they were large
floppy devices. LOCKDRV.FLT allows removable media such as MO's to be
supported as though they were fixed hard drives.
o It is not possible to install OS/2 3.0 on drives with capacity greater
than 8 GB, nor in a partition greater than 4 GB. The following is the
suggestion from IBM on this problem:
Problems with large partitions and installation or booting
--------------------------------------------------------------
There is a BIOS restriction that installable (startable) or bootable
partitions must be contained within the first 1024 physical cylinders
of the disk. FDISK does not enforce this limitation.
If you have installation or boot failures this could be the reason.
Use FDISK to reduce the size of your startable or bootable partition by
sufficient MBytes. One way to calculate the correct size partitions to
do the following:
1) Edit your CONFIG.SYS and add the following parameter to the
BASEDEV=IBM1S506.ADD line as below:
BASEDEV=IBM1S506.ADD /V
2) Save this change.
3) Reboot your system.
4) At initialization, record the far left hand column of number of
the Geometry information under the ACT heading.
Example: ACT Cyl 1027 Head 63 Sec 128
(head x sec) /2 = bootable partition must be contained within this
boundary in MBytes (round down)
This is the maximum size of a bootable partition in MBytes. Any
bootable partition must also be contained from the beginning of the
drive to this number of MBytes. A bootable partition may be smaller
than the maximum size but still must be contained within this boundary.
In this example the bootable partition must be contained in the first
4032 MBbytes of the disk and cannot exceed a single partition size of
4032 MBytes within this area. No bootable partition may extend beyond
the first 4032 MBytes.
Use this information when configuring your bootable partition with FDISK.
o OS/2 will allocate the SCSI devices as the order in CONFIG.SYS if two
drivers (AIC7870.ADD and AIC78U2.ADD) are loaded.
o OS/2 will assign drive letters for SCSI devices first then IDE devices.

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 :
a. For Ultra2SCSI host adapter:
BASEDEV=AIC78U2.ADD [Universal Parameter][Adapter ID][Unit Parameter]
{[SCSI Target ID]}
b. For UltraSCSI or earlier host adapters:
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. (Refer to the Configuration Examples in the
"General Unit Parameters" section below for information on how to
use this option.)
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=AIC78U2.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=AIC78U2.ADD /A:0 /TAG:8
will set the number of tagged commands for all target
devices on the first host adapter to 8.
