Section 2 DOS Installation
---------------------------
2.0 Installing DOS Drivers Using the Setup Utility
The DOS software drivers can be installed manually or by
using the Setup Utility.
The Install utility, is a menu-based utility for installing and
configuring your SCSI, ASPI, and CD-ROM drivers. It automatically
updates your CONFIG.SYS and AUTOEXEC.BAT files and creates a backup
copy of the original files with .OLD extension. Install runs under
version 6.0 or later of MS-DOS.
If you use the Setup program, you do not need to perform the
manual installation procedures in section 2.2
To use Setup, follow these steps.
1. Boot to DOS (not WinNT or Win9x).
2. Insert the QLogic diskette in an appropriate drive.
3. At the DOS prompt, type (drive letter):INSTALL followed by
the <ENTER> key.
Example:
A:INSTALL
4. Follow the screen prompts to access the README.TXT file or
Press <ENTER> to continue.
5. The system prompts "Will you be connecting a CD-ROM to your
system". Click on YES if you are connecting a SCSI CD-ROM
to the QLogic SCSI adapter.
6. Follow the directions displayed on the screen to complete the
installation process.
7. Press the <ENTER> key to exit the program. Remove the QLogic
software diskette from the drive AFTER you exit the program.
The following example shows what is added to your CONFIG.SYS file
in a standard installation:
DEVICEHIGH=C:\QLC\QL26ASPI.SYS
DEVICEHIGH=C:\QLC\QL00CDRM.SYS /D:QLC0000
NOTE: If you have disabled the BIOS or you do not have a hard drive
attached to the QLogic adapter, then you MUST load the QLogic
DOS driver (QL26ASPI.SYS) in the CONFIG.SYS file
before the memory manager.
Example:
DEVICE=C:\QLC\QL26ASPI.SYS
DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE
This completes the automatic installation of the DOS and CD-ROM
drivers. For additional information, configuration options or
manual installation of the DOS drivers, read the following
sections.
2.1 DOS Driver and Switch Options
The QLogic SCSI adapter has an onboard BIOS PROM that provides
support for booting the system from a SCSI disk. This BIOS requires
a SCSI disk to be attached or it will disable itself. If you use
devices other than a hard disk, you need to load the RAM based BIOS
that is provided (QL26ASPI.SYS). Use of the DOS driver offers
enhanced performance and additional functionality.
Using the DOS driver is mandatory when you install the CD-ROM driver.
The DOS driver and the CD-ROM driver are also provided on the QLogic
diskette.
The following option switches may be appended to the DOS
driver (QL26ASPI.SYS) found in the CONFIG.SYS file: (Using these
switches will override any jumpers on the adapter)
/D or /DISPLAY
Will display all SCSI devices attached to the adapter when the RAM
driver is loaded.
/E
This will disable the ASPI portion of the DOS driver. It is not
recommended to disable this unless you are sure ASPI support is
not required.
/NOR or /NORISC
This will disable loading RISC code.
/NOS or /NOSEEK
This will disable SCSI seek commands.
Example of command line parameter in the config.sys file:
DEVICE=C:\QLC\QL26ASPI.SYS /DISPLAY
2.2 Manually installing the DOS Driver
Note: Manual installation is not necessary if you have already
run the installer.
Perform the following steps to install the DOS driver.
1. Place the QLogic diskette in the A: drive.
2. Create a directory on the boot drive of the computer to store
the driver.
Example:
MD C:\QLC
3. Copy the DOS driver file from the diskette to the
directory created in step 2.
Example:
COPY A:\DOS\QL26ASPI.SYS C:\QLC\*.*
4. Add the DOS driver to your CONFIG.SYS file.
Example:
DEVICE=C:\QLC\QL26ASPI.SYS
NOTE: If you do not have a hard drive attached to the QLogic SCSI
adapter or you have disabled the adapter's BIOS, make sure the
line that loads the DOS driver is before the line that
loads the memory manager (e.g. HIMEM.SYS).
5. If you want to use any of the option switches, append them to
the DEVICE= line in your CONFIG.SYS file.
Example:
DEVICE=C:\QLC\QL26ASPI.SYS /DISPLAY
6. Save your edited CONFIG.SYS file.
7. Reboot the system.
2.3 DOS CD-ROM Driver and Command Line Parameter
The DOS CD-ROM driver provides the interface between the
Microsoft MSCDEX.EXE program and the CD-ROM device attached to
the QLogic SCSI adapter. The QLogic DOS driver (QL26ASPI.SYS),
CD-ROM driver (QL00CDRM.SYS), and Microsoft's MSCDEX.EXE program
are required for accessing the CD-ROM device as a data disc.
The DOS CD-ROM driver supports the following mandatory parameter:
/D:QLC0000
Example:
DEVICE=C:\QLC\QL00CDRM.SYS /D:QLC0000
This specifies the name of your CD-ROM driver. The /D in the
parameter does NOT refer to the drive letter of the CD-ROM.
An identical parameter is also used when loading the MSCDEX.EXE
program. The signature name is used by the MSCDEX.EXE program to
determine with which drive to communicate.
Make sure the driver name you supply to the MSCDEX.EXE program is
identical to the one you used with the DOS CD-ROM driver.
NOTE: The MSCDEX.EXE program is provided by Microsoft with MS-DOS
version 6.0 and above. If you are running an older version
of MS-DOS, contact Microsoft to obtain MSCDEX.EXE.
2.3.1 Installing the QLogic DOS CD-ROM Driver
Before you can install the QLogic DOS CD-ROM driver, you must
first install the DOS driver (QL26ASPI.SYS).
Perform the following steps to install the DOS CD-ROM driver.
1. Place the QLogic diskette in the A: drive.
2. Copy the DOS CD-ROM driver file from the diskette to the
computer's boot drive.
Example:
COPY A:\DOS\QL00CDRM.SYS C:\QLC\*.*
3. Add the DEVICE= line to your CONFIG.SYS file.
Example:
DEVICE=C:\QLC\QL00CDRM.SYS /D:QLC0000
Make sure the line that loads the CD-ROM driver is after the
line that loads the DOS driver.
Example:
DEVICE=C:\QLC\QL26ASPI.SYS
DEVICE=C:\QLC\QL00CDRM.SYS /D:QLC0000
4. Save your edited CONFIG.SYS file.
5. Install the MSCDEX.EXE program in your AUTOEXEC.BAT file.
Example:
C:\DOS\MSCDEX.EXE /D:QLC0000
6. Save your edited AUTOEXEC.BAT file.
7. Reboot the system.
Section 3 Troubleshooting
-------------------------
3.1 Problems After Installation
There are four basic types of problems that can occur after
installation that may cause your QLogic SCSI adapter to function
incorrectly: hardware problems, system problems, driver problems,
and SCSI problems. The following sections help you determine why
your QLogic SCSI adapter is not functioning.
3.2 Hardware Problems
Are there any loose boards in the PC?
Are there any loose connections to the internal or external SCSI
drives?
Is the SCSI adapter seated correctly in the PC? The gold-
fingered edge should not be visible. This is important since
some enclosures may not allow the adapter to be fully seated.
Are all external peripherals properly connected and the system
powered up?
3.3 System Problems
Check the motherboard and make any configuration changes
necessary to accommodate the SCSI adapter. The SCSI adapter is
configured by the system's BIOS. If you have the option of
PCI bus level triggering or edge triggering, choose level.
See the documentation for the motherboard to determine if it
requires configuration. Disable the motherboard IDE interface(s)
in the system Bios if you wish to use the SCSI drive as the boot
device. If you do not have any documentation, contact the dealer
from whom you purchased your computer.
If your system message is "Missing Operating System" or "No ROM
BASIC, System Halted", the boot drive is not set as the active
partition in FDISK, or the disk drive attached to the SCSI adapter
is not partitioned in a format compatible with the adapter. Use the
DOS FDISK and format utility as required (typical DOS
installation techniques).
Not all adapter manufacturers use the same geometry when
formatting disk drives. QLogic uses the Microsoft standard of 64
heads, 32 sectors per track for drives less than one gigabyte and
255 heads, 63 sectors per track for drives greater than one
gigabyte. This may attribute to problems if you move the drive
from one manufacture's SCSI controller to another. If the drive
is not formatted with this geometry, you need to partition and
format the drive using the DOS FDISK and FORMAT utilities.
3.4 Driver Problems
If you are having problems with a particular device or software
application, you may need updated QLogic drivers. We are
continually updating drivers to maintain compatibility with other
manufacturer's hardware and software. You can access the latest
information and drivers from the QLogic WEB page at http://www.qlc.com.
3.5 SCSI Problems
Are all the SCSI devices plugged in and turned on before you
power up the PC? Power up all external SCSI devices, then power
up the PC.
Does each device have a unique SCSI ID? Each device must have its
own unique ID between 0 and 15. The QLogic SCSI adapter is factory
set for SCSI ID 7.
Is termination on the QLogic SCSI adapter set correctly?
Is termination for all devices on the SCSI bus set correctly?
SCSI bus termination is one of the most important aspects and
considerations for proper device operation. QLogic must emphasize
the need for proper SCSI bus termination. Please confirm that
termination is enabled at each end of the SCSI bus only, not in the
middle. Do not exceed cable length!
NOTE: The total length of all cables cannot exceed 6 meters
(19.6 feet) for non-Ultra devices. On systems with Ultra
drives, the total length is limited to 1.8 meters
(6 feet) of quality cable. Ensure that pin 1 of the cable
is properly aligned.
Are all the cables firmly attached and properly oriented to
their correct ports?
Have you installed the proper device driver for the QLogic SCSI
adapter? See the installation sections in this readme file that
apply to the drivers you want.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
