BusLogic FlashPoint PCI SCSI Host Adapter Driver
For IBM OS/2 2.1x/Warp
Version 1.50
Introduction
============
BusLogic's FlashPoint PCI SCSI Adapter Driver FLASHPT.ADD Ver 1.50
runs under IBM OS/2 2.1, 2.11 and 3.0 (Warp). This README file
contains instructions on installing this driver on these OS/2
platforms and describes the various command line switches available
to tailor the device driver to your needs.
The installation procedures covered in this README file are as
follows:
I. Installation on OS/2 Warp
II. Installation on OS/2 2.1x
III. Installation with IDE as Primary
IV. Miscellaneous Notes
I. Installation on OS/2 Warp
============================
Installation of OS/2 driver can be performed in one of two ways,
depending on whether OS/2 is being installed from diskettes or
CD-ROM.
Floppy Installation
-------------------
Install OS/2 using the embedded INT 13 driver. After
installation, perform the following steps:
1. Insert the BusLogic SW-200 Software Drivers diskette in
the floppy drive.
2. Double-click, in order, the OS/2 System, System Setup,
and Device Driver Install icons.
3. Press the Change button in the Source directory.
4. Select, in order, the OS2 and Warp directories.
5. Click on the Install button.
6. Select the BusLogic FlashPoint driver and press OK.
OS/2 automatically updates the CONFIG.SYS file for
the new driver.
7. Eject the driver diskette and reboot the system.
CD-ROM Installation
-------------------
To perform this procedure, you will need to modify the OS/2
installation diskette labeled "Diskette 1". Make a copy of
that diskette and use the duplicate diskette whenever
"Diskette 1" is called for in these instructions.
1. On a DOS or OS/2 system, insert the BusLogic SW-200
Software Drivers diskette in the floppy drive and copy
the FlashPoint OS/2 driver to a temporary directory on
the hard disk.
C:\> MD MYTEMP
C:\> CD MYTEMP
C:\MYTEMP> COPY A:\OS2\WARP\FLASHPT.ADD
2. Remove the diskette from the floppy drive and insert
Diskette 1. You will have to delete another driver from
the diskette so that you can copy the FlashPoint OS/2 driver
onto it. In the following example, the AIC7870 driver is
replaced with the FlashPoint driver.
C:\MYTEMP> DEL A:\AIC7870.ADD
C:\MYTEMP> COPY FLASHPT.ADD A:\
3. Edit CONFIG.SYS and replace the line
BASEDEV=AIC7870.ADD
with
BASEDEV=FLASHPT.ADD
Save the changes.
Note: Do not position the FLASHPT.ADD as the first
ADD driver in the CONFIG.SYS file. OS/2 keys off the
default first ADD entry during installation.
4. Perform the installation using the modified Diskette 1.
Note that during installation, the System Configuration
window will not display the FlashPoint driver in the
SCSI Adapter Support list box. This is OK. Simply select
the OK button and proceed.
II. Installation on OS/2 2.1x
=============================
Installation of OS/2 driver can be performed in one of two ways,
depending on whether OS/2 is being installed from diskettes or
CD-ROM.
Floppy Installation
-------------------
Install OS/2 using the embedded INT 13 driver. After
installation, perform the following steps:
1. Insert the BusLogic SW-200 Software Drivers diskette in
the floppy drive.
2. Double-click, in order, the OS/2 System, System Setup,
and Device Driver Install icons.
3. Press the Change button in the Source directory.
4. Select, in order, the OS2 and 2.1X directories.
5. Click on the Install button.
6. Select the BusLogic FlashPoint driver and press OK.
OS/2 automatically updates the CONFIG.SYS file for
the new driver.
7. Open an OS/2 window and overwrite the OS2LDR file on
the hard disk as follows:
A:
A:\> CD OS2\2.1X
A:\OS2\2.1X> ATTRIB -S -H -R C:\OS2LDR
A:\OS2\2.1X> COPY OS2LDR C:\
A:\OS2\2.1X> ATTRIB +S +H +R C:\OS2LDR
8. Eject the driver diskette and reboot the system.
CD-ROM Installation
-------------------
CD-ROM installation requires the FlashPoint device driver
during the OS/2 installation, therefore, changes to the
OS/2 installation diskettes are necessary. Make backup
copies of the Installation diskette and CD-ROM Install
Diskette 1. Use the duplicates to perform the modifications
below.
1. On a DOS or OS/2 system, insert the BusLogic SW-200
Software Drivers diskette in the floppy drive and copy
the files from the OS/2 2.1X directory to a temporary
directory on the hard disk.
C:\> MD MYTEMP
C:\> CD MYTEMP
C:\MYTEMP> COPY A:\OS2\2.1X\*.*
2. Remove the diskette from the floppy drive and insert
the CD-ROM Install Diskette 1. Copy the FLASHPT.ADD
and IBMINT13.I13 onto the diskette as follows:
C:\MYTEMP> COPY FLASHPT.ADD A:\
C:\MYTEMP> COPY IBMINT13.I13 A:\
3. Edit CONFIG.SYS to insert the following line at the
beginning of the file:
BASEDEV=FLASHPT.ADD
Save the changes.
Note: Do not position the FLASHPT.ADD as the first ADD
driver in the CONFIG.SYS file. OS/2 keys off the default
first ADD entry during installation.
4. Now remove the diskette and insert the OS/2 Installation
diskette. Copy OS2LDR onto the diskette as follows:
C:\MYTEMP> COPY OS2LDR A:\
5. Perform the installation using the modified diskettes
up to the point where files have been installed from
the CD-ROM and you are requested to reboot from the
hard disk. Instead, reboot from the Installation
diskette and CD-ROM Install Diskette 1. Escape out
of the installation procedure to the system prompt.
6. Remove the CD-ROM Install Diskette 1 and insert the
SW-200 Software Drivers diskette in the floppy drive.
Follow the steps below to update the hard disk with the
PCI-aware OS2LDR and IBMINT13.I13 files.
A:
A:\> CD OS2\2.1X
A:\OS2\2.1X> ATTRIB -S -H -R C:\OS2LDR
A:\OS2\2.1X> ATTRIB -S -H -R C:\OS2\IBMINT13.I13
A:\OS2\2.1X> COPY OS2LDR C:\
A:\OS2\2.1X> COPY IBMINT13.I13 C:\OS2
A:\OS2\2.1X> ATTRIB +S +H +R C:\OS2LDR
A:\OS2\2.1X> ATTRIB +S +H +R C:\OS2\IBMINT13.I13
Remove the diskette and reboot the system to proceed
with installation from the hard disk.
Note that the next stage of the installation, the System
Configuration window will not display the FlashPoint
driver in the SCSI Adapter Support list box. This is OK.
Simply select the OK button and proceed.
III. Installation with IDE as Primary
=====================================
Installation of OS/2 driver can be performed in one of two ways,
depending on whether OS/2 is being installed from diskettes or
CD-ROM using a CD-ROM drive attached to a BusLogic host adapter.
Floppy Installation
-------------------
Follow the Floppy Installation instruction described
in Section I or II above.
CD-ROM Installation
-------------------
Follow the CD-ROM Installation instruction described
in Section I or II above.
When OS/2 Installation presents the System Configuration
window, perform device driver installation as described
in the Floppy Installation instruction in Section I or
II above.
Reboot the system using <Ctrl-Alt-Del> without closing
the System Configuration window. Upon boot up, you will
be prompted with the same window with the BusLogic
FlashPoint driver in the SCSI Adapter Support list box.
Proceed with the installation.
IV. Command Line Switches
=========================
BusLogic's FlashPoint OS/2 Adapter Device Driver supports the
following command line switches:
I. Global Switches
------------------
/V Verbose switch. This switch enables driver verbosity at
initialization time.
/QU Warning-error suppression switch. When invoked, the driver
will not complain about references to non-existent targets/
luns specified on the BusLogic ADD driver command line.
/O Early Opti chipset work-around switch. This switch
provides a work-around for an early version of the Opti
PCI chipset which can generate spurious interrupts. Do
not use this option unless your system hangs at boot-time
and you are using an Opti chipset.
/SH Allow sharing of IRQ across different host adapter
families. This option is not necessary when sharing IRQ
within FlashPoint product family. Side-effect of using
this switch is less responsive mouse and keyboard event
recognition during heavy I/O.
II. Per-Host Adapter Switches
-----------------------------
/A:x Adapter identification switch. x is between 0 and 5 and
identifies the adapter being referenced. This switch is
followed by one or more of the switches below.
/<!>DM:xx
DASD Manager Support switch. As defined by IBM, this switch
enables/disables support for this unit by the IBM-supplied
DASD Manager (OS2DASD.DMD).
/<!>SM:xx
SCSI Manager Support switch. As defined by IBM, this switch
enables/disables support for this unit by the IBM-supplied
SCSI Manager (OS2SCSI.DMD).
/TQ Enable tagged queuing support on ALL targets on the
specified host adapter (specified by the receding /A:
switch) that supports tagged queuing. If this switch is
Tagged queuing is an advanced SCSI-II feature that allows
overlapped commands to a SCSI device, this results in
enhanced performance. While BusLogic provides support for
this important SCSI-II feature, not all SCSI devices support
tagged queuing. The SCSI device must support tagged
queuing to take advantage of this feature.
BusLogic's OS/2 SCSI Adapter Driver defaults to tagged
queuing DISABLED on all devices. For devices that support
tagged queuing, the following command line switches are
provided to manage tagged queuing support on a finer
device-specific level.
/TQ:x,y,z,...
Enable tagged queuing support on a specified list of
SCSI targets. x,y,and z is a list of embedded SCSI targets
separated by commas. The Logical Unit Number (LUN) is
presumed to be 0.
/TQ:(a,b), (c,d), ...
Enable tagged queuing support on a specified list of
pairs of SCSI targets/LUNs in parenthesies. Each
parenthesied pair is separated by commas.
Examples:
1) BASEDEV=FLASHPT.ADD /A:0 /TQ
This example enables tagged queuing on host
adapter 0 on all targets that support it. Targets
attached to host adapter 0 that do not support
tagged queuing are not affected.
2) BASEDEV=FLASHPT.ADD /A:0 /TQ /A:1 /TQ
This example enables tagged queuing on all
targets on host adapters 0 and 1 that support it.
Targets attached to host adapters 0 and 1 that do
not support tagged queuing are not affected.
3) BASEDEV=FLASHPT.ADD /A:0 /TQ:0,2,3 /A:2 /TQ:0,1
This example enables tagged queuing on targets
0, 2, and 3 on host adapter 0 and on targets 0 and
1 on host adapter 2. If any of the specified
targets are not attached or do not support tagged
queuing, specification of those particular devices
is ignored.
4) BASEDEV=FLASHPT.ADD /A:0 /TQ:(0,0),(2,1)
This example enables tagged queuing on target 0
LUN 0 and target 2 LUN 1 on host adapter 0. If
any of the specified target/LUN combinations are
not attached or do not support tagged queuing,
specification of those particular devices is
ignored.
/LUNS:xx
This switch specifies the maximum number of Logical Units
(LUNs) the host adapter will support (try to detect). If
the switch is not specified, the default is 8. Valid range
is from 1 to 32. If the host adapter only has embedded
SCSI targets attached (that is, all attached devices are
at LUN 0), it is recommended to set this option value to
1 to turn off LUN support for LUNS other than 0.
Examples:
1) BASEDEV=FLASHPT.ADD /A:0 /LUNS:1
This example effectively disables lun support on
host adapter #0.
2) BASEDEV=FLASHPT.ADD /A:0 /LUNS:4
This example scans up to 4 LUNS on host adapter #0.
/TO:xx
Command Timeout switch. This per-host adapter switch
specifies a timeout on each I/O request in seconds.
It takes a decimal digit input between 1 and 99. The driver
default is 15 seconds in this absence of this switch.
Setting the timeout value to 0 turns off the timeout
mechanism.
Note: This switch has no effect on tape requests.
Example:
BASEDEV=FLASHPT.ADD /A:0 /TO:10
This example causes the driver to wait 10 seconds
before timing out on an outstanding request.
/MR:xx
Maximum Request switch. This per-host adapter switch
specifies the maximum number of requests that can be
pending on the host adapter. Valid range is 1 - 64.
Default is 16.
/MA:xx
Maximum Active switch. This per-host adapter switch
specifies the maximum number of active requests that
can be outstanding on each device on the host adapter.
Valid range is 1 - <Max Requests>. Default is 8. This
value can be adjusted to increase performance.
V. Miscellaneous Notes
======================
1. To use a third-party ASPI driver (such as Corel SCSI) on a
particular SCSI ID, you must disable the OS/2 DASD and SCSI
managers as follows in the BASEDEV line in CONFIG.SYS:
BASEDEV=FLASHPT.ADD /!DM:3 /!SM:3
The example disables the DASD and SCSI managers on SCSI ID 3.
2. Boot drive ID selection in AutoSCSI will not work with this
OS/2 driver.
3. The OS2LDR included for OS/2 Version 2.1x in this release
does not support SMP. You will need a version of OS2LDR from
IBM that supports both SMP and PCI configuration to install
the FlashPoint driver.
