QLogic PCI SCSI Adapter - QLA12160 Drivers for DOS 6.0 and later Release Notes: -------------- This release has been tested with DOS 6.0 and all available versions and service packs as of this date. Note: Before installation, make a backup copy of the QLogic Software Diskette. This document is divided into 3 Sections Section 1 DOS files on this disk Section 2 DOS Installation Section 3 Troubleshooting Section 1 DOS files on this disk --------------------------------- The following files on this disk support DOS 6.0 and above: QL26ASPI.SYS - DOS SCSI Driver including ASPI support. QL00CDRM.SYS - DOS Driver that allows support for CD-ROM devices. INSTALL.BAT - This is the batch file you execute to install the DOS Drivers. README.TXT - This file. Note: The remaining files in the root directory of this disk are support files for the QLogic utilities. 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
