Setting jumpers

You configure your card to match the needs of your application by setting jumpers. A jumper is the simplest kind of electric switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To “close” a jumper you connect the pins with the clip. To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3. In this case you would connect either pins 1 and 2 or 2 and 3.

The jumper sesttings are schematically depicted in this manuaal as follows:

Open Closed Closed 2-3

A pair of needle-nose pliers may be helpful when working with jumpers.

If you have any doubts about the best hardware configuration for your application, contact your local distributor or sales representative before you make any changes.

Generally, you simply need a standard cable to make most connections.

CPU installation and upgrading

You can upgrade to a higher power Pentium processor at any time. Simply remove the old CPU, install the new one, and set the jumpers for the new CPU type and speed.

Warning!

Caution!

Always disconnect the power cord from your chassis when you are working on it. Do not make connections while the power is on as sensitive electronic components can be damaged by the sudden rush of power. Only experienced electronics personnel should open the PC chassis.

Always ground yourself to remove any static charge before touching the PC board. Modern electronic devices are very sensitive to static electric charges. Use a grounding wrist strap at all times. Place all electronic components on a static-dissipative surface or in a static-shielded bag when they are not in the chassis.

Install a CPU in the ZIF socket

PCA-6159 Series provides a Zero Insertion Force (ZIF) socket for easy CPU installation.

1.Make sure the ZIF socket lever is in the upright position. To raise the lever, pull it out to the side a little and raise it as far as it will go.

2.Place the CPU in the empty socket. Follow the instructions that came with the CPU. If you have no instructions, do the following: Carefully align the CPU so it is parallel to the socket and the notch on the corner of the CPU corresponds with the notch on the inside of the socket. Gently slide the CPU in. It should insert easily. If it doesn’t, pull the lever up a little more.

3.Press the lever down. The plate will slide forward. You will feel some resistance as the pressure starts to secure the CPU in the socket. This is normal and won‘t damage the CPU.

When the CPU is installed, the lever should snap into place at the side of the socket.

NOTE: To remove a CPU, pull the lever out to the side a

little and raise it as far as it will go. Lift out the CPU chip.

When you install a new CPU, be sure to adjust the board settings, such as CPU type and CPU clock. Improper settings may

damage the CPU.

Voltage Select (J1, J2, J3, and J4)

J1, J2, J3, and J4 must be set to match the CPU type. The chart below shows the proper jumper settings for their respective Vcc

(core). (The Vcc (I/O) for CPU is fixed to be 3.3V).

Installing DRAM (SIMMs)

The PCA-6159 Series CPU card provides four 72-pin SIMM (Single In-line Memory Module) sockets and supports either Fast Page Mode (FPM) or Extended Data Output (EDO) DRAM with a speed of 70 ns or faster. You can install up to 256 MB of RAM.

Installing SIMMs

NOTE: The modules can only fit into a socket one way.

Their chips must face the CPU, and their gold pins must point down into the SIMM socket.

1.Ensure that all power sources are disconnected.

2.Slip the memory module into the socket at a 45-degree angle.

3.Push the module toward the vertical posts at both ends of the

socket until the module is upright, and the retaining clips at both ends of the module click into place. When positioned correctly, the pins on top of the vertical posts should correspond to the circular holes on the ends of the module.

4.Repeat steps 2 and 3 for each module you install.

Front panel connectors (CN1,CN2,CN3,CN4)

You may want to install external switches to monitor and control the PCA-6159 Series. These features are optional —install them only if you need them. The front panel connectors include a speaker connector (CN1), a HDD LED connector (CN2), an input switch (CN3) for resetting the card, and a keyboard lock connector (CN4).

Speaker connector (CN1)

The PCA-6159 Series can drive an 8 Ω speaker at 0.5 watts. Ensure that alternatives to this specification do not overload the card. Close pins 3 and 4 to enable the buzzer.

HDD LED connector (CN2)

The LED indicator for hard disk access is an active low signal (24 mA sink rate).

Reset switch (CN3)

If you install a reset switch, it should be an open single pole switch. Momentarily pressing the switch will activate a reset. The switch should be rated for 10 mA, 5 V.

Power LED/keyboard lock connector (CN4)

You can connect an LED to indicate if the CPU card is powered on. Pin 1 of CN4 supplies power to the LED, and pin 3 is the ground.

You can use a switch (or a lock) to disable the keyboard. In this state, the PC will not respond to any input from the keyboard. This is useful if you don’t want anyone to change or stop a running program. Simply connect the switch between pin 4 and pin 5 of CN4.

If you need to make your own cable, you can find the pin assignments for the board’s connector in Appendix B.

Fan power supply connector (CN5)

CN5 provides power supply to optional CPU cooling fan. Only present when +12 V power is supplied to the board.

SCSI connectors (CN6, CN7)

The PCA-6159 Series has a 50-pin, dual in-line connector for Ultra SCSI devices and a 68-pin, dual in-line connector for Ultra Wide SCSI devices. Connection of SCSI devices requires special attention, especially when determining the last drive on the SCSI chain. Refer to Chapter 6 and your device’s operating manual for detailed installation advice.

IDE hard drive connector (CN8, CN9)

You can attach up to four Enhanced Integrated Device Electronics hard disk drives to the PCA-6159 Series internal controller. The PCA-6159 Series IDE controller uses a PCI local-bus interface. This advanced IDE controller supports faster data transfer and allows the IDE hard drive to exceed 528 MB.

CN8 is the primary IDE connector, CN9 is the secondary IDE connector. Each connector supports up to two EIDE hard disk drives.

Connecting the hard drive

The way to connecting drives to primary IDE connector or secondary IDE connector is same.

Wire number 1 on the cable is red or blue, and the other wires are gray.

1.Connect one end of the cable to CN8/CN9. Make sure that the red (or blue) wire corresponds to pin 1 on the connector.

2.Plug the other end of the cable to the Enhanced IDE hard drive, with pin 1 on the cable corresponding to pin 1 on the hard drive. (See your hard drive’s documentation for the location of the connector.)

Connect a second drive as described above. Unlike floppy drives, IDE hard drives can connect to either end

of the cable. If you install two drives, you will need to set one as the master and one as the slave by using jumpers on the drives. If you install just one drive, set it as the master.

Floppy connector (CN10)

You can attach up to two floppy drives to the PCA-6159 Series on-board controller. You can use any combination of 5¼” (360 KB and 1.2 MB) and/or 3½” (720 KB, 1.44 MB, and 2.88 MB) drives.

A 34-pin daisy-chain drive connector cable is required for a dualdrive system. On one end of the cable is a 34-pin flat-cable connector. On the other end are two sets of floppy disk drive connectors. Each set consists of a 34-pin flat-cable connector (usually used for 3½” drives) and a printed-circuit board connector (usually used for 5¼” drives).

Connecting the floppy drive

1.Plug the 34-pin flat-cable connector into CN10. Make sure

that the red wire corresponds to pin one on the connector.

2.Attach the appropriate connector on the other end of the cable

to the floppy drive(s). You can use only one connector in the set. The set on the end (after the twist in the cable) connects to the A: drive. The set in the middle connects to the B: drive.

3.If you are connecting a 5¼” floppy drive, line up the slot in

the printed circuit board with the blocked-off part of the cable connector. If you are connecting a 3½” floppy drive, you may have trouble determining which pin is pin number one. Look for a number printed on the circuit board indicating pin number one. In addition, the connector on the floppy drive connector may have a slot. When the slot is up, pin number one should be on the right. Check the documentation that came with the drive for more information.

If you desire, connect the B: drive to the connectors in the middle of the cable as described above.

If you need to make your own cable, you can find the pin assignments for the board’s connector in Appendix B.

VGA interface connections

The PCA-6159H/F/V PCI SVGA interface can drive conventional CRT displays and is capable of driving a wide range of flat panel displays, including electroluminescent (EL), gas plasma, passive LCD and active LCD displays. The board has two

connectors to support these displays, one for standard CRT VGA monitors and one for flat panel displays.

CRT connector (CN16)

CN16 is a standard 15-pin D-SUB connector commonly used for VGA.

Pin assignments for CRT connector CN16 are detailed in Appendix B.

Flat panel connector (CN11)

CN11 consists of a 44-pin, dual-in-line header. The PCA6159H provides a bias control signal on CN11 that can

be used to control the LCD bias voltage. It is recommended that the LCD bias voltage not be applied to the panel until the logic supply voltage (+5V or +3.3V) and panel video signals are stable. Under normal operation, the control signal (ENAVEE) is active high. When the PCA-6159H power is applied, the control signal is low until just after the relevant flat panel signals are present.

LCD power select (J12)

The PCA-6159H/F/V PCI SVGA interface supports 5V and 3.3V LCD displays. By changing the setting of J12, you can select the panel video signal level to be 5V or 3.3V.

LCD power select

*5 V 3.3 V

J12

* default setting

Configuration of the VGA interface is done completely via the software utility. You don’t have to set any jumpers. Refer to Chapter 3 for software setup details.

Refer to Chapter 3 for details on connecting the four standard LCD’s: Sharp LM64183P, LM64P89, Toshiba LTM10C042, Sharp 64C142, and Planar EL Display.

Keyboard connectors (CN12, CN19)

The PCA-6159 Series board provides two keyboard connectors. A 5-pin connector (CN12) supports passive backplane applications. A second 6-pin mini-DIN connector (CN19) supports both a keyboard and a PS/2 style mouse.

COM-port connectors (CN13, CN17)

The PCA-6159 Series has two serial ports, COM1 and COM2, to provide connections for serial devices (a mouse, etc.) or a

communication network. You can find the pin assignments for the COM port connectors in Appendix B.

The IRQ and the address range for COM1, 2, are fixed. However, if you wish to disable the port or change these parameters later you can do this in the system BIOS setup. The table below shows the settings for the PCA-6159 Series serial ports.

PCA-6159 Series serial port default settings

Port Address Range Interrupt

COM1 3F8~3FF IRQ4

COM2 2F8~2FF IRQ3

Printer port connector (CN14)

Normally, the parallel port is used to connect the card to a printer. The PCA-6159 Series includes a multi-mode (ECP/EPP/ SPP) parallel port, accessed through CN14, a 26-pin flat-cable connector. You will need an adapter cable if you use a traditional DB-25 connector. The adapter cable has a 26-pin connector on one end and a DB-25 connector on the other.

The parallel port is designated as LPT1 and can be disabled or changed to LPT2 or LPT3 in the system BIOS setup.

The parallel port interrupt channel is designated to be IRQ7.

You can select ECP/EPP DMA channel via BIOS setup.

IR connector (CN15)

This connector supports the optional wireless infrared transmitting and receiving module. This module mounts on the system case. You must configure the setting through BIOS setup.

USB connectors (CN18, CN20)

The PCA-6159 Series provides two USB (Universal Serial Bus) interfaces which gives complete plug and play, hot attach/detach for up to 127 external devices. The USB interfaces comply with USB specification rev. 1.0 and are fuse protected.

The USB interfaces are accessed through two 5-pin flat-cable connectors, CN18 and CN20. You will need an adapter cable if you use a standard USB connector. The adapter cable has a 5-pin connector on one end and an USB connector on the other.

The USB interfaces can be disabled in the system BIOS setup.

Ethernet connector (UTP1, PCA-6159H/F only)

The PCA-6159H/F is equipped with a high performance 16-bit PCI-bus Ethernet interface which is fully compliant with IEEE

802.3 10Mbps CSMA/CD standards. It is supported by all major network operating systems and is 100% Novell NE-2000 compatible. On board RJ-45 jack provides convenient 10 Base-T RJ-45 operation.

The medium type can be configured via the RSET8029.EXE program included on the utility disk. (See Chapter 3 for detailed information.)

Watchdog timer configuration

An on-board watchdog timer reduces the chance of disruptions which EMP (electro-magnetic pulse) interference can cause. This

is an invaluable protective device for standalone or unmanned applications. Setup involves one jumper and running the control software (refer to Appendix A).

Watchdog select (J14)

When the watchdog timer activates (CPU processing has come to a halt), it can reset the system or generate an interrupt on IRQ11. This can be set via setting J14 as shown below:

Watchdog select

*System reset IRQ11

J14 11

22 33

* default setting

For information on programming the watchdog timer, see Appendix A.

VGA display software configuration

The PCA-6159H/F/V on-board VGA interface supports a wide range of popular LCD, EL, gas plasma flat panel displays and traditional analog CRT monitors. With on-board 1M display memory, the interface can drive CRT displays with resolutions up to 1024 x 768 in 256 colors. It is also capable of extending up to 2 MB of display memory to provide resolutions of 1024 x 768 in 64K colors.

The VGA interface is configured completely via the software utility, so you don’t have to set any jumpers. Configure the VGA display as follows:

1.Apply power to the PCA-6159H/F/V with a color TFT display attached. This is the default setting for the PCA6159H. Ensure that the AWDFLASH.EXE and *.BIN files are located in the working drive.

NOTE: Ensure that you do not run AWDFLASH.EXE

while your system is operating in EMM386 mode.

2.At the prompt, type AWDFLASH.EXE and press <Enter>.

3.At the prompt, enter the new BIN file that supports your display. When you are sure that you have entered the file name correctly, press <Enter>.

4.The screen will ask “Do you want to save BIOS?” Press Y if you wish to save the existing configuration before changing it. Then type the name under which you want to save the current configuration.

5.The prompt will then ask “Are you sure to program?” Press Y if you want the new file to be written into the BIOS. Press N to exit the program.

The new VGA configuration will then write to the ROM BIOS chip. This configuration will remain the same until you run the AWDFLASH.EXE program and change the settings.

Award BIOS Setup

This chapter describes how to set BIOS configuration data.

System test and initialization

These routines test and initialize board hardware. If the routines encounter an error during the tests, you will either hear a few short beeps or see an error message on the screen. There are two kinds of errors: fatal and non-fatal. The system can usually continue the boot up sequence with non-fatal errors. Non-fatal error messages usually appear on the screen along with the following instructions:

press <F1> to RESUME

Write down the message and press the F1 key to continue the bootup sequence.

System configuration verification

These routines check the current system configuration against the values stored in the board’s CMOS memory. If they don’t match, the program outputs an error message. You will then need to run the BIOS setup program to set the configuration information in memory.

There are three situations in which you will need to change the CMOS settings:

1. You are starting your system for the first time

2. You have changed the hardware attached to your system

3. The CMOS memory has lost power and the configuration information has been erased.

The PCA-6159 Series CMOS memory has an integral lithium battery backup. The battery backup should last ten years in normal service, but when it finally runs down, you will need to replace the complete unit.

AWARD BIOS setup

PCI SVGA Setup (PCA-6159H/F/V only)

The PCA-6159H/F/V features an onboard PCI flat panel/VGA interface. This chapter provides instructions for installing and operating the software drivers on the included display driver diskette.

Before you begin

To facilitate the installation of the enhanced display device drivers and utility software, you should read the instructions in this chapter carefully before you attempt installation. The enhanced display drivers for the PCA-6159H/F/V board are located on the software installation diskette. You must install the drivers and utility software by using the supplied SETUP program for DOS drivers

Note: The files on the software installation diskette are

compressed. Do not attempt to install the drivers by copying the files manually. You must use the supplied SETUP program to install the drivers.

Before you begin, it is important to note that most display drivers need to have the relevant software application already installed in the system prior to installing the enhanced display drivers. In addition, many of the installation procedures assume that you are familiar with both the relevant software applications and operating system commands. Review the relevant operating system commands and the pertinent sections of your application software’s user’s manual before performing the installation.

Installation

Disk 1: Windows 3.1, Windows 95, and Windows NT drivers Disk 2: OS/2 drivers

Simultaneous display mode

The 65550 VGA BIOS supports monochrome LCD, EL, color TFT and STN LCD flat panel displays. It also supports interlaced and non-interlaced analog monitors (VGA color and VGA monochrome) in high-resolution modes while maintaining complete IBM VGA compatibility. Digital monitors (i.e. MDA, CGA, and EGA) are NOT supported. Multiple frequency (multisync) monitors are supported as analog monitors.

Both CRT and panel displays can be used simultaneously. The PCA-6159H/F/V can be set in one of three configurations: on a CRT, on a flat panel display, or on both simultaneously. The system is initially set to simultaneous display mode. In the utility diskette, there are three .COM files that can be used to select the display. Simply type the filename at the DOS prompt:

CT.COMEnables CRT display only FP.COMEnables panel display only SM.COMEnables both displays at the same time.

Sleep mode

The display driver diskette contains two files that support sleep mode. Simply type the filename at the DOS prompt:

ON.COM switches to normal display mode. OFF.COM switches to sleep mode.

Driver installation

Necessary prerequisites

The instructions in this manual assume that you understand elementary concepts of MS-DOS and the IBM Personal Computer. Before you attempt to install any driver or utility you should: know how to copy files from a floppy disk to a directory on the hard disk, understand the MS-DOS directory structure, and know how to format a floppy disk. If you are uncertain about any of these concepts, please refer to the DOS or Windows user reference guides for more information before you proceed with the installation.

Before you begin

Before you begin installing software drivers, you should make a backup copy of the display driver diskette and store the original in a safe place. The display driver diskette contains drivers for several versions of certain applications. You must install the correct version in order for the driver to work properly so make sure you know which version of the application you have.

The following steps must be performed before you install the 65550/554 display driver:

1.OS/2 DOS Support must be installed.

2.If you previously installed SVGA support, you must reset the

system to VGA mode. VGA is the default video mode enabled when OS/2 is installed.

To restore VGA mode, use Selective Install and select VGA for Primary Display. For more information on this procedure, see the section on Changing Display Adapter Support in the OS/2 User’s Guide.

Installing from Diskette

To install this driver, do the following steps:

1.Open an OS/2 full screen or windowed session.

2.Place the 65550 PCI Display Driver Diskette in drive A.

3.At the OS/2 command prompt, type the following commands

to copy the files to the OS/2 drive: Type:

A: <ENTER> to make this the default drive.

SETUP A: C: <ENTER>

whereA: is the floppy disk drive and

C: is the hard disk partition containing \OS2

When the Setup Program is completed, you will need to perform a shutdown and then restart the system in order for changes to take effect.

A log of the information output during the install can be found in <root>:\OS2\INSTALL\DISPLAY.LOG

4.After restarting the system, perform the following steps:

1).Open the OS/2 System folder.

2).Open the System Setup folder.

3).Open the Display Driver Install Object

This step will execute the Display Driver Installation (DSPINSTL) utility program to finish installation of the new drivers.

4).When the Display Driver Install window appears, select Primary Display and then select OK.

5).When The Primary Display Driver List window appears, select “Chips and Technologies 65550/554” from the list of adapter types, then select OK to install the video driver.

6).When the installation is complete, you will need to shutdown and then restart the system for the changes to take effect. Make sure to remove the install diskette before restarting the system.

When the system has restarted, the display driver will be initialized for 640x480x256 Color, 60Hz refresh. To switch to a different video resolution color depth, or refresh rate, follow the steps below.

Selecting Monitor Type

Monitor type is initially set to DEFAULT. This DEFAULT setting may not allow you to select all resolution/refresh combinations that are available for your monitor. The following steps can be done to select monitor type. This section applies only after installation, or when a different monitor is used.

1.Open the OS/2 System folder.

2.Open the System Setup folder.

3.Open the System object.

4.When the System - Settings notebook appears, select the Screen tab. This will take you to page 2 of the settings.

5.On Screen page 2, select your monitor type from the Display Name list. If your monitor is not listed, select DEFAULT. Return to Screen page 1.

It may be necessary to restart your system to have all refresh rate options available.

Selecting Screen Resolution/Refresh Rate

To switch to a different video resolution, color depth or refresh rate,

follow the steps below.

1.Open the OS/2 System folder.

2.Open the System Setup folder.

3.Open the System object.

4.From the selection windows provided, select a new Screen Resolution and Screen refresh rate.

Please note, Refresh rates, other than 60Hz, are only valid when the display is switched to CRT only display mode.

5.Close the System-Settings notebook.

6.Perform a shutdown and restart for the changes to take effect.

Installation Notes

1.During the installation of this driver, DISPLAY.LOG and DSPINSTL.LOG files are created in \OS2\INSTALL directory. These files identify the OS/2 system files that were updated, and indicate whether the installation was successful. The DISPLAY.LOG file also contains a string that identifies the version of driver that was installed. This information may be important when reporting an installation problem.

2.During installation, DSPINSTL will invoke the SVGA Configuration program SVGA.EXE to determine the hardware configuration, and create the file \OS2\INSTALL\SVGADATA.PMI. If this file is not created, the adapter will not be supported. When this step is done, the display will be blanked, and you may see a series of flashes on the display and/or what appears to be a “corrupted” display. This is normal, as the configuration process is doing Video BIOS mode sets to determine which screen resolutions BIOS supports. This configuration information is then used to provide the System-Settings Resolution and Refresh selections.

SCSI Setup and Configurations

The PCA-6159/H/F is equipped with two SCSI interfaces. This chapter provides basic SCSI concepts and instructions for installing the software drivers with the included SCSI driver diskettes. At the end of this chapter provides the SCSI device troubleshooting tips.

Installation and Setup

The PCA-6159/H/F is equipped with an Adaptec AIC-7880 Ultra Wide PCI-to-Ultra SCSI host adapter which provides a powerful multitasking interface between your computer’s PCI bus and SCSI devices (disk drives, CD-ROM drives, scanners, tape backups, removable media drives, etc.). Up to a total of 15 SCSI devices can be connected to the internal or external SCSI connector on AIC-7880.

If you need to configure the SCSI, the onboard SCSI Select configuration utility allows you to change host adapter settings without opening the computer or handling the board. The SCSI Select utility also contains a utility to low-level format and verifies the disk media on your hard disk drives.

SCSI Configuration Guidelines

Before installing your SCSI devices, you should understand the basic SCSI concepts described in this section. The information will help you set up your host adapter and devices so they function properly.

SCSI ID Numbers

Each device attached to the host adapter, as well as the host adapter itself, must have a unique SCSI ID number (0-15). The SCSI ID serves two purposes:

- It uniquely defines each SCSI device on the SCSI bus.

- It determines the device’s priority on the SCSI bus.

SCSI ID7 has the highest priority. The priority of the remaining IDs, in descending order, is 6 to 0 and 15 to 8.

Note: SCSI IDs play no role in determining the order in

which devices are cabled to the host adapter.

The AIC-7880 supports the SCSI Configured AutoMatically (SCAM) protocol, which assigns SCSI IDs dynamically and resolves SCSI ID conflicts automatically at bootup. If your system includes SCSI disk drives or other devices that support SCAM, you do not need to manually assign SCSI IDs to these devices.

Most SCSI devices currently in use, however, do not support SCAM. The SCSI IDs on these devices must be set manually. To change the SCSI IDs on these devices, refer to the device’s documentation.

If you install more than one SCSI host adapter in the computer, each adapter forms a separate SCSI bus. SCSI IDs can be reused as long as the ID is assigned to a device on a separate SCSI bus (e.g., each SCSI bus can have a device with SCSI ID 0).

SCSI Terminators

To ensure reliable communication, the SCSI bus must be properly terminated. Termination is controlled by a set of electrical resistors, called terminators. Terminators must be placed (or enabled) at the two extreme ends of the SCSI bus. All devices that lie between the ends must have their terminators removed (or disabled).

Termination on the Ultra Wide SCSI itself is controlled by software commands via the SCSISelect utility. The default setting is set to Automatic. When set to Automatic, if the AIC7880 detacts that SCSI cables are connected to any of its two SCSI connectors, it automatically sets the termination setting for the low and high bytes of the 16-bit Wide SCSI bus. The low byte controls 8-bit SCSI; the low and high bytes together control 16-bit Wide SCSI.

We recommend that you leave SCSI set to its default setting of Automatic. The following table lists the termination configurations.

Termination

Devices Connected Low High

68-pin internal connector only ON ON

50-pin internal connector only ON ON

50-pin and 68-pin internal connectors OFF ON

SCSI Termination Examples

Installing SCSI Devices

You can connect up to 15 devices (seven standard internal and eight Wide (16-bit) internal SCSI devices, or 15 Wide internal SCSI devices) to the Ultra Wide SCSI.

Connecting Internal SCSI Devices

If you are connecting internal SCSI devices, make sure you have an internal SCSI cable with enough connectors to accommodate all of your devices.

1. Prepare each SCSI device for installation; configure the

device SCSI ID and terminators (terminate the last internal device attached to the cable).

2. Install the SCSI device in your computer. Refer to your

computer and device documentation for instructions.

3. Plug the connector at one end of the internal SCSI cable into

the host adapter’s internal SCSI connector. Make sure the colored stripe on one side of the cable is aligned

with pin-1 of the host adapter’s connector. Pin-1 of the connector is usually designated by a small triangle “∆”, or a “1” on the connector.

4. Plug the remaining connectors on the cable into the connec-

tors on the back of the devices. Make sure the colored stripe on the cable is aligned with pin-1 of

the device’s connector.

5. Connect a DC power cable (from your computer’s power

supply) to the power connector on the SCSI device.

Configuring the SCSI Adapter

Access the SCSI BIOS by holding down both CTRL and A keys when you see the BIOS banner message listing the driver name and the attached devices. For example:

<<<Press <Ctrl><A> for SCSISelect(TM) Utility>>> The SCSISelect screen will come up. Instructions on how to

move the cursor and select options are listed on the bottom of the program widows. You can select either Configure/View Host Adapter Settings or SCSI Disk Utilities.

Configure/View Host Adapter Settings Host Adapter SCSI Termination. Low ON/High ON

- When using 50-pin connector only, choose “Low ON/High

ON” (Default)

- When using 68-pin connector only, choose “Low ON/High

ON” (Default)

- When using both 50-pin & 68-pin, choose “Low OFF/High

ON”

Select the default of “Low ON/High ON?” and press Enter, then use the up and down arrows to make your new selection and press Enter. Press ESC to go back to the Options menu. Press ESC again and select Yes to exit the program.

Basic Host Adapter Settings

The basic host adapter settings are the SCSISelect settings most likely to require any modification.

n Host Adapter SCSI ID - This option sets the host adapter’s

SCSI ID. The default setting is SCSI ID 7, which give the

host adapter the highest priority on the SCSI bus. We recommend that you leave the host adapter set to SCSI ID7.

n SCSI Parity Checking - This option determines whether

the host adapter verifies the accuracy of data transfer on the SCSI bus. The default setting is Enabled. You should disable SCSI Parity Checking if any SCSI device connected to the PCA-6159/59H does not support SCSI parity; otherwise, leave it enabled. Most SCSI devices do support SCSI parity. If you are not sure whether a device supports SCSI parity, consult the documentation for the device.

n Host Adapter SCSI Termination - This option sets

termination on the host adapter. The default setting for the on-board SCSI is low ON/High ON. If you want to manually set the termination setting, see SCSI Terminators for appropriate settings.

Boot Device Settings

The boot device settings allow you to specify the device from which you wish to boot your computer.

n Boot Target ID - This option specifies the SCSI ID of the

device you wish to boot from. The default setting is SCSI ID 0. The SCSI ID selected here must correspond to the ID configured on the boot device.

n Boot LUN number - If your boot device has multiple

LUNs (Logical Unit Numbers) and Multiple LUN Support is enabled, this option allows you to specify which LUN to boot from on your boot device. The default setting is LUN

SCSI Device Settings

The SCSI device settings allow you to configure certain parameters for each device on the SCSI bus. To configure a specific device, you must know the SCSI ID assigned to that device. If you are not sure of the SCSI ID, see Using the SCSI Disk Utilities on page78.

n Initiate Sync Negotiation - This option determines whether

the host adapter initiates synchronous data transfer negotiation (Sync Negotiation) between the device and host adapter. The default setting is Yes.

Synchronous negotiation is a SCSI feature that allows the host adapter and its attached SCSI devices to transfer data in synchronous mode. Synchronous data transfer is faster than asynchronous data transfer.

The host adapter always responds to Sync Negotiation if the SCSI device initiates it. If neither the host adapter nor the SCSI device initiate Sync Negotiation, data is transferred asynchronously.

Normally, you should leave the Initiate Sync Negotiation setting enabled, because most SCSI devices support synchronous negotiation and it allows for faster data transfer.

Note: Some older SCSI-1 devices do not support Sync

Negotiation. This may cause your computer to operate erratically or hang if Initiate Sync Negotiation is set to yes. Set Initiate Sync Negotiation to No for these devices.

n Initiate Wide Negotiation —This option determines

whether the host adapter attempts 16-bit data transfer (Wide negotiation) instead of 8-bit data transfer. The default setting is Yes.

Note: Some 8-bit SCSI devices may have trouble

handling Wide negotiation, which may result in erratic behavior or a hang condition. For these devices, set Initiate Wide Negotiation to No.

When set to Yes, the host adapter attempts 16-bit transfer. When set to No, 8-bit data transfer is used unless the SCSI

device itself requests Wide negotiation. The effective transfer rate is doubled when 16-bit data transfer is sued because the data path for Wide SCSI is twice the size of normal 8-bit SCSI. For example, a transfer rate of 10 Mbytes/sec becomes 20Mbytes/sec, and a transfer rate of 20 Mbytes/sec (Ultra SCSI) becomes 40 Mbytes/sec.

n Maximum Sync Transfer Rate – This option sets the

maximum synchronous data transfer rate that the host adapter supports. The default setting is 20.0 for the Ultra Wide SCSI. The host adapter supports rate up to the Ultra SCSI maximum of 20.0 Mbytes/sec (Ultra Wide SCSI provides an effective maximum synchronous transfer rate of

40.0 Mbytes/sec). If your device is an Ultra SCSI device, you can use the maximum value of 20.0. If your device is not an Ultra SCSI device select a transfer rate of 10.0. If the host adapter is set not to negotiate for synchronous data transfer (that is, Initiate Sync Negotiation is set to no), then the maximum synchronous transfer rate is the maximum rate that the host adapter accepts from the device during negotiation. (This is standard SCSI protocol.).

n Enable Disconnection – This option determines whether

the host adapter allows the SCSI device to disconnect from the SCSI bus (sometimes called Disconnect/Reconnect). Enabling disconnection allows the host adapter to perform other operations on the SCSI bus while the SCSI device is temporarily disconnected. The default setting is Yes. You should leave Enable Disconnection set to yes if two or more SCSI devices are connected to the host adapter. This optimizes SCSI bus performance. If only one SCSI device is connected to the host adapter, set Enable Disconnection to No to achieve slightly better performance.

n Send Start Unit Command – This option determines

whether the Start Unit Command is sent to the SCSI devices at boot up (most devices do not require this). The default setting is No.

Setting this option to yes reduces the load on your computer’s power supply by allowing the host adapter to start SCSI devices one-at-a-time when you boot your computer. When set to No, the devices are allowed to start at the same time. Most devices require you to set a jumper before they can respond to this command.

Note: If the Send Start Unit Command is set to yes for

many devices, the boot time will vary depending on how long it takes each drive to start.

Advanced Host Adapter Settings

The advanced host adapter settings should not be changed unless absolutely necessary.

n Plug and Play SCAM Support - This option determines

whether the SCSI automatically assigns SCSI Ids to attached SCSI Devices that support the SCAM protocol. The default setting is Disabled. Most non-SCAM devices tolerate SCAM protocol, so you can enable this option even for non-SCAM devices. In rare cases, an old SCSI-1 device may not tolerate SCAM and may cause the computer to hang or operate erratically. If this happens, disable this option.

n Host Adapter BIOS – This option enables or disables the

host adapter BIOS. The default setting is Enabled.

Note: Several SCSISelect options are not valid unless

the host adapter BIOS is enabled.

If you are booting from a SCSI disk drive connected to the host adapter, the BIOS must be enabled. You should disable the host adapter BIOS if the peripherals on the SCSI bus (for example, CD-ROM drives) are all controlled by device drivers and do not need the BIOS.

n Support Removable Disks Under BIOS as Fixed Disks

— This option controls which removable-media drives are supported by the host adapter BIOS. This default setting is Boot Only. The following choices are available:

Boot Only – Only the removable-media drive designated as the boot device is treated as a hard disk drive.

All Disks – All removable-media drives supported by the BIOS are treated as hard disk drives.

Disabled – No removable-media drives are treated as hard disk drives. In this situation, software drivers are needed because the drives are not controlled by the BIOS.

Caution: If a removable-media SCSI device is controlled by the host adapter BIOS, do not remove the media while the drive is on or you may lose data! If you want to be able to remove media while the drive is on, install your removable-media device driver and set this option to Disabled.

n Extended BIOS Translation for DOS Drives >1 Gbyte –

This option determines whether extended translation is available for SCSI hard disks with capacities greater than 1 GByte. The default setting is Enabled.

Caution: If you decide to change the translation scheme, back up your disk drives first! All data is erased when you change from one translation scheme to another.

The standard translation scheme for SCSI host adapters provides a maximum accessible capacity of 1 GByte. To support disk drives larger than 1 GByte, the Ultra Wide SCSI includes an extended translation scheme. This scheme supports disk drives as large as 8 GBytes under MS_DOS with a maximum partition size of 2 GBytes.

Extended BIOS Translation is used only with MS-DOS 5.0 or above. You do not need to enable this option if you are using another operating system such as NetWare, OS/s, Windows NT, or UNIX.

When you partition a disk larger than 1 GByte, use the MS-DOS disk utility as you normally would. Because the cylinder size increases to 8 Mbytes under extended translation, the partition size you choose must be a multiple of 8Mbytes. If you request a size that is not a multiple of 8MBytes, fdisk rounds up to the nearest whole multiple of 8MBytes.

n Display <Ctrl-A> Message during BIOS Initialization –

This option determines whether the Press <Ctrl> <A> for SCSISelect ™ Utility message appears on your screen during system boot up. The default setting is Enabled. If this setting is disabled, you can still invoke the SCSISelect utility by pressing <Ctrl> <A> after the host adapter BIOS banner appears.

n Multiple LUN Support – This option determines whether

booting from a SCSI device that has multiple LUNs is supported. The default setting is Disabled. Enable this option if your boot device has multiple LUNs.

n Support for Ultra SCSI Speed – This option determines

whether the host adapter supports the fast transfer rates (13.4, 16,20.0) of Ultra SCSI devices. The default setting is Disabled.

Using SCSISelect Menus

SCSISelect menus list options you can select. To select an option, use the↑ and↓ keys to move the cursor to the option, then press Enter.

In some cases, selecting an option displays another menu. You can return to the previous menu at any time by pressing Esc. To restore the original SCSISelect default values, press F6. To toggle the display between color and monochrome modes, press F5 (this feature may not work on some kinds of monitors).

Using the SCSI Disk Utilities

To access the SCSI disk utilities, select the SCSI Disk Utilities option from the menu that appears after starting SCSISelect. Once the option is selected, SCSISelect immediately scans the SCSI bus (to determine the devices installed) and displays a list of all SCSI IDs and the devices assigned to each ID.

When you select a specific ID and device, a small menu appears, displaying the options Format Disk and Verify Disk Media.

n Format Disk – This utility allows you to perform a low-

level format on a hard disk drive. Most SCSI disk devices are preformatted at the factory and do not need to be formatted again. The Adaptec Format Disk utility is compatible with the vast majority of SCSI disk drives.

Caution: A low-level format destroys all data on the drive. Be sure to back up your data before performing this operation. You cannot abort a low-level format once it is started.

n Verify Disk Media – This utility allows you to scan the

media of a hard disk drive for defects. If the utility finds bad blocks on the media, it prompts you to reassign them; if you select yes, those blocks are no longer used. You can press Esc at any time to abort the utility.

Installing Device Drivers

Some operating systems embed (included) the AIC-7880 Ultra Wide SCSI device driver as part of their installation software. These drivers work fine with your AIC-7880 Ultra Wide SCSI; however, the most recent version of the driver should be installed in order for your AIC-7880 Ultra Wide SCSI to perform at its optimum level.

n Adaptec EZ-SCSI – allows you to install software drivers

for DOS/Windows 3.x and several additional utilities.

n Adaptec 7800 Family Manager Set – allows you to install

software drivers for NetWare, OS/2, Windows 95, Windows NT, and UNIX. Refer to the 7800 Family Manager Set User’s Guide.

Troubleshooting Tips

SCSI Device Troubleshooting

Review this checklist if your newly installed SCSI disk drives, CDROM drives, and other devices do not seem to work properly:

Be sure that termination is correctly set for all devices on the SCSI bus, as described in your host adapter documentation.

Be sure there are no hardware conflicts such as devices in your computer trying to use the same interrupts (IRQs) or DMA channels.

Be sure the cables connecting the external and internal SCSI devices and the host adapter are attached securely. Also be sure the pin-1 orientation is correct for internal cables.

Be sure that each SCSI device connected to the host adapter has a unique SCSI ID.

Be sure CD-ROM drives and other SCSI devices are attached to a power source and are turned ON.

Windows 95 / Windows NT Troubleshooting

What is a miniport driver, and how do I make sure that the miniport driver is installed correctly?

Miniport drivers are new kind of 32bit protect mode device drivers used by Windows 95 and Windows NT to control host adapters and other kinds of devices. Windows 95 and Windows NT include a set of miniport drivers for various types of SCSI host adapters. The host adapter miniport driver is automatically installed and configured during Windows 95 and Windows NT installation if your host adapter is already installed. To make sure the driver is installed correctly in systems running Windows 95, open the Control Panel, double-click on System, and click the Device Manager tab. Then double-click the SCSI Controllers icon; you should see the model name of the SCSI host adapter(s) installed in your system.

What if there is no SCSI controller icon under Device Manager, or the model name of the SCSI chipset does not appear under Device Manager:

If the SCSI controllers icon or your host adapter’s model name do not appear, open Control Panel and double-click the Add New Hardware icon. Let Windows search for the host adapter by selecting Yes on the second screen of the Add New Hardware Wizard.

If Windows does not detect the host adapter, run the Add New Hardware Wizard again. This time, select No on the second screen of the wizard, then select SCSI controllers on the next screen. Select the name of your host adapter when it appears.

If the name of your SCSI chipset does not appear, you may be able to find its miniport driver o the Windows 95 CD-ROM.

Follow these steps:

1. Place the Windows 95 CD-ROM in your CD-ROM drive

and run the Add New Hardware wizard.

2. Select No on the second screen, and select SCSI controllers

on the next screen.

3. Click on the Have Disk button, then click the browse

button.

4. Look in the \drivers\storage directory of the CD-ROM and

select the name of your SCSI host adapter if it appears.

What if a yellow exclamation point or a red X appears in Device Manager in front of my host adapter?

1. Open the Control Panel, double-click on System, and click

the Device Manager tab.

2. Double-click the SCSI Controllers icon, select the name of

the old host adapter, and click Remove.

3. Turn OFF the computer and physically remove the currently

installed host adapter.

4. Install the new host adapter according to the instructions in

the hardware documentation.

5. Turn the computer ON. If the new host adapter supports

Plug and Play, Windows will install and configure it automatically. Otherwise, run Add New Hardware to make sure the new driver is loaded.

If I am running under Windows 95, do I need lines for the Adaptec real mode ASPI drivers and mscdex in my config.sys and autoexec.bat files?

Usually, you do not need to use these real mode ASPI drivers, because the new Windows miniport drivers support most SCSI host adapters and SCSI devices. However, you need to load the drivers (including mscdex, if you have a CD-ROM drive) if any of the following is true:

− You are running in MSDOS mode.

− You are using a scanner or another SCSI device with

config.sys - or autoexec.bat- based drivers, such as HP’s sjiix.sys.

− You have an older model SCSI-1 CD-ROM drive that

Windows 95 does not support.

− You are using a CD-Recorder drive (however, some newer

models of CD-Recorder drives can use the embedded

Windows miniport drivers). To install the Adaptec EZSCSI DOS drivers, click the Start button and select Restart the computer in MS-DOS mode. When the DOS prompt appears, follow the Quick Start instructions for DOS.

My CD-ROM drive doesn’t work properly under Windows 95.

Some older models of SCSI CD-ROM drives are not compatible with the embedded Windows 95 CD-ROM driver. You can add support for the CD-ROM drive by doing the following:

1. Click the Start button and select Restart the computer in

MS-DOS mode.

2. When the DOS prompt appears, follow the Quick Start

instructions for DOS.

3. When you are finished running Adaptec EZSCSI for DOS,

find the file named cdtsd.vxd in the

windows\system\iosubsys directory and rename it cdtsd.sav.

My CD-ROM drive shows up as more than one icon under My Computer.

The mapping between mscdex, which runs in real mode, and the Windows95 CDROM driver does not match. You can correct this in one of two ways:

− Comment out the line that loads mscdex.exe in the

autoexec.bat file.

− Change the /L switch on the line that loads mscdex.exe in

the autoexec.bat file so it assigns the CD-ROM drive the

next highest logical drive letter after the hard disk drives.

Information for DOS/Windows 3.1x Users

The following information may be useful if you install Adaptec EZSCSI on a computer running DOS, Windows 3.1x, or Windows for Workgroups 3.1x.

Note: The Windows 95/Windows NT Troubleshooting

section describes a few situations when you may need to use the DOS/Windows 3.1x drivers and ASPI managers under Windows 95 or Windows NT.

Device drivers are software programs that enable your computer to communicate with SCSI devices such as hard disk drivers, CDROM drives, and scanners. Each kind of device requires a different device driver. Adaptec EZSCSI includes several DOS/ Windows 3.1x device drivers that are copied to your hard disk during installation. Adaptec EZSCSI adds command lines to your config.sys and autoexec.bat files to load these device drivers if it finds these kinds of devices on your computer.

To learn more about the Adaptec EZSCSI device drivers, including their command line option information, see the online Adaptec EZSCSI Online Reference, a Windows Help application.

DOS and Windows 3.1x ASPI Managers

ASPI (Advanced SCSI Programming Interface) managers are software programs that enable the SCSI device drivers, your host adapter, and your SCSI devices to communicate with each other. ASPI managers are written for a specific operating system, such as DOS, and a specific family of Adaptec host adapters.

Adaptec EZSCSI includes several ASPI managers for DOS/ Windows 3.1x. When you install Adaptec EZSCSI on these operating systems, it detects what kind of host adapter is installed in your computer and automatically configures your system with

the correct ASPI manager. To learn more about these ASPI managers, including their command line option information, see the Adaptec EZSCSI Online Reference, a Windows Help application.

DOS Formatting Utilities

Adaptec EZSCSI includes several DOS-based formatting utilities;

Low-level Formatter (scsifmt)

Use the DOS-based scsifmt utility for low-level formatting of SCSI hard disk drives, removable media, Floptical® drives. You can also use it to scan a disk device for surface defects before you store data on it.

Run scsifmt from the DOS prompt, not from the Windows MSDOS prompt. Before you run it, be sure the disk devices you want to format are connected to the host adapter and that they are powered. Then follow these steps:

1. Change to the directory where scsifmt.exe is located

(usually c:\scsi), type scsifmt at the DOS prompt, and press

Enter.

NOTE: If you are formatting a SCSI disk device that supports more than one LUN (for example, Iomega’s Bernoulli dual multidrive) type scsifmt/L at the command line.

2. When the first screen appears, read it and press Enter to

continue. (Press F1 at any time to view Help). Information

about your SCSI disk devices appears on the screen.

3. Use the arrow keys to move the highlight bar to a disk

device you want to format or verify, then press Enter.

4. When the next screen appears, select either Format or

Verify (to verify that the disk is free of surface defects),

then press Enter.

WARNING: Back up important data before you format the disk device! A low-level format erases all data from the disk.

5. If you select Format, confirm that you want to format the disk, then wait while the disk device is formatted. This may take a long time if the disk is large. If you select Verify, you can press Esc at any time to stop the verification process. (This does not damage the disk.) If the utility finds bad blocks on the disk, it displays information about them. You can reassign the bad block(s) to prevent data from being stored there.

6. Repeat steps 3,4, and 5, as needed, to format or verify other disk devices. When you are finished, press Esc to exit.

Formatter and Partitioner (afdisk)

Use the DOS-based afdisk utility to partition and format SCSI hard disk drives, Floptical® drives, and magneto-optical dries. You can also use afdisk to remove DOS and non-DOS partitions from a disk drive and to format removable media in standard hard disk format, OS/2 floppy format, or DOS V (Japanese) format.

NOTE: Use afdisk only if the disk device is not controlled

by the host adapter BIOS – that is, if the host adapter does not have BIOS or if its BIOS is not enables. If the disk device is controlled by the host adapter BIOS, use the DOS fdisk utility to partition and format the disk device. (See the MSDOS documentation.).

Run afdisk from the DOS prompt only, not from the Windows MSDOS prompt. Before you run it, be sure the disk devices you want to format and partition are connected to the host adapter

and that they are powered. Then follow these steps:

1. Change to the directory where afdisk.exe is located (usually c:\scsi), type afdisk at the DOS prompt, and press Enter. Information about your SCSI disk devices appears on the screen. (The number that appears after Target is the device’s SCSI ID).

2. Use the arrow keys to move the highlight bar to the disk device you want to partition, then press Enter.

− If the selected disk device is controlled by the host adapter BIOS, you can view information about it but you cannot partition it with afdisk (Use the DOS fdisk and format utilities.)

− If the selected disk device is unpartitioned, you must partition it before you can format it. To do this, follow the instructions on the screen. (Press F1 to see an explanation of the partitioning options.) Information about the selected disk device appears in the lower left of the screen. Disks smaller than 1Gbyte have 64 heads, 32 sectors per track, and cylinders equal to the number of MBytes of available capacity. Disks larger than 1Gbyte have 255 heads, 63 sectors per track, and one cylinder per 8MBytes of available capacity.

3. To create a new partition on the disk device, press Ins. The “Create a DOS Partition” window appears in the lower right of the screen and suggests that you create one partition on the disk device, equal to its entire capacity. If this is what you want to do, skip to step 5.

4. To change the size of the partition, use the arrow keys to select Start Cylinder and End Cylinder, and type in the numbers you want. Partitions up to 2GBytes are supported.

5. When the number of cylinders is what you want, press Esc. When the confirmation prompt appears, select Yes and press Enter to create the partition. To create more partitions

on the same disk device, repeat steps 3,4, and 5. As you create partitions on the disk., they are added to the window at the upper right of the screen.

6. Press Esc to return to the “Select SCSI Device to Partition” window. If you want to partition a different disk device, select the device from the list and repeat the earlier steps.

7. To quit afdisk, press Esc and select Yes to confirm that you want to quit.

Programming the Watchdog Timer

The PCA-6159 Series is equipped with a watchdog timer that resets the CPU or generates an interrupt if processing comes to a standstill for whatever reason. This feature ensures system reliability in industrial standalone, or unmanned, environments.
