Configuration
1-2 FlashPoint™ LT BT-930 User’s Manual
Configuration
Plug and Play Operation. FlashPoint adapter configuration is handled by
the PCI motherboard. Operating parameters can be adjusted using
AutoSCSI, a menu-driven utility residing in the adapter’s Read Only
Memory (ROM).
Features
The FlashPoint PCI host adapter has the following features:
• Fast data transfer rates
The FlashPoint supports standard data transfer rates including Fast
SCSI-2 at 10 megabytes per second and Ultra SCSI rates at 20
megabytes per second.
• SCAM Support
The FlashPoint supports the SCSI-3 SCAM (SCSI Configured
Automatically) ConLevels 1 and 2 protocols for SCSI ID assignment.
SCAM devices do not require manual SCSI ID assignment. The
FlashPoint adapter assigns a SCSI ID to the device as required. See the
owner’s manual for your peripheral devices to determine whether or
not they support SCAM.
• SmartTerm
The FlashPoint has no onboard jumpers. With SmartTerm, the
FlashPoint adapter determines the configuration of the daisy chained
devices, and self-terminates as required. See the owner’s manual for
your SCSI devices to determine how they support termination.
•SeqEngine
SeqEngine provides automated SCSI command processing which
reduces SCSI command overhead by minimizing the need to interface
with the host processor. This results in improved performance.

Introduction
Manual No. 3000863 1-5
PC-DOS, MS-DOS and Windows. Your host adapter’s onboard BIOS
allows you to attach up to seven SCSI disk drives without additional
software under PC or MS-DOS 5.0 and above. Earlier versions of DOS only
allow support for up to two hard disk drives.
Mylex offers device drivers that support ASPI (Advanced SCSI Program
Interface) for configurations where more hard drives are needed than your
version of DOS can support. Mylex also offers CDROM drivers for DOS and
Windows.
If you are installing other types of devices under DOS and Windows, such as
a tape backup device or a scanner, you will need to install additional drivers
that support the ASPI interface to operate those devices. Those drivers are
usually available packaged with the device or from third party sources.
☛Note
You can obtain the latest Mylex driver updates from
the Mylex Bulletin Board System (BBS) for host
adapter products, via modem at 510-793-3491. (Up to

Chapter 2
Installation
This section details hardware installation. See Chapter 3 for information on
using AutoSCSI to configure adapter operating parameters.
What’s Covered in This Section
1. Unpacking the adapter and preparing for installation
2. Installing your FlashPoint
3. Configuring and cabling internal SCSI devices
4. Configuring and cabling external SCSI devices
5. Powering up the system
6. Hard drive set up
Unpacking
Before handling the FlashPoint, take precautions to avoid damage from
electrostatic discharge: either use a grounding strap, or, touch your a metal
part of your computer chassis to discharge static electricity before handling
the board. Always hold the board by the edges, even after static electricity is
discharged.
1. Check that your shipment is complete with cables, documentation and
diskette.
2. Remove the board from its protective envelope.
3. Verify that no physical damage occurred during shipping by inspecting
the board for bent pins, loose parts, broken traces, and chipped or
broken connectors.

Installation Tools
2-2 FlashPoint™ LT BT-930 User’s Manual
Warranty Information
If damage to the board has occurred, return it in the protective envelope and
original packaging with this manual to your Mylex board supplier. The
shipping agent should also be notified if the unit has been damaged during
shipment. The Mylex warranty conditions are given in the back of this
manual.
Installation Tools
The following items may be needed to assist with installing the adapter into
your system:
• Small screwdriver
• Host system hardware manuals and manuals for the peripherals being
installed.
Setting the SCSI Device ID
Each SCSI device is assigned a unique SCSI ID ranging from 0 through 7.
Most SCSI peripheral devices are shipped with a preassigned SCSI ID
number. Your FlashPoint is, by default, SCSI ID 7.
If you need to change the SCSI ID for a peripheral device, refer to the
instructions in its owner’s manual. A SCSI ID jumper or switch is usually
located on the peripheral’s back panel.
To change your adapter SCSI ID use the View/Modify Adapter Configuration
option on the AutoSCSI’s Adapter Configuration Menu (Chapter 3, “Adapter
and Device Configuration”).
☛Note
FlashPoint LT allows the user the option of selecting
the boot drive and specifying its SCSI ID through
AutoSCSI. If the SCSI ID of the boot drive is set to
zero then BIOS looks for the boot drive by scanning
devices according to their SCSI ID, starting at SCSI
ID 0. In this case, make sure that your boot device has
the lowest SCSI ID.

Installation
Manual No. 3000863 2-3
SCAM Support
The FlashPoint adapter supports SCAM Levels 1 and 2. If your peripheral
device supports SCAM, the FlashPoint adapter will determine an available
SCSI ID and assign it to the device.
SCSI peripheral devices that do not support SCAM (legacy) are shipped with
a preassigned SCSI ID number. You can change this ID if necessary. A SCSI
ID switch is usually located on the back panel of such devices. It may be in
the form of a jumper or a switch whose setting indicates the SCSI ID. If you
need to change the SCSI ID for the other peripheral devices, refer to the
instructions in the owners manual for the device.
Terminating SCSI Devices
The SCSI devices connected on the ends of the cable of a SCSI bus must
have terminators installed or enabled. Terminators, which can be connected
to either SCSI devices or SCSI cables, are required for reliable operation of
the SCSI bus.
☛Note
Pass through cable terminators may not properly
terminate the device. For greater reliability, Mylex
recommends the use of active terminators for all
devices.
If more than two SCSI devices are connected in a SCSI daisy chain, disable
the termination on the middle device(s).
The FlashPoint is equipped with SmartTerm™ and does not require any
physical configuration for termination. SmartTerm requires no user
interaction and automatically enables or disables the FlashPoint termination
depending on the configuration of the SCSI bus in the system.
☛Note
There are devices on the market, such as some pass
through terminators and devices with 26-pin DB
connectors, that do not conform to SCSI
specifications. With such devices on the cable, the
SmartTerm logic on the FlashPoint LT board does not

work properly. To overcome this problem, the
FlashPoint adapters provide an AutoSCSI option to
disable onboard termination.
Installing Your FlashPoint
Step 1: Prepare the host system and the adapter
When you are ready to begin, power down the host system.
Referring to your host system owner’s manual, remove the covers to open
the case to gain access to the motherboard and expansion slots as shown in
Figure 2-1.
If the computer has been on, wait a few minutes until the power supply case
has cooled down inside the computer. If the power supply case is cold, touch
it to discharge any static electricity that may be on your clothes or body.
Figure 2-1. Remove the Cover and Bracket
To install the adapter card, remove the mounting screw and the existing
bracket from the rear panel behind the selected PCI slot.

Installation
Manual No. 3000863 2-5
☛Note
The FlashPoint adapter can only be installed in a
busmaster slot. Refer to your system documentation to
determine the correct slot for installation.
Step 2: Install the adapter
Press the FlashPoint adapter into the selected PCI slot (see Figure 2-2).
Align the mounting bracket, and reinstall the mounting screw.
Figure 2-2. FlashPoint adapter Installation
mCaution
Make sure that the board is properly seated in the slot.
Step 3: Install internal devices and cables
Internal devices require a 50-pin flat ribbon cable. Use the ribbon cable
included with the FlashPoint to install one or two internal devices. Install
one end of the ribbon cable to the 50-pin double-row SCSI connector on the
FlashPoint host adapter (see Figure 2-3).
Before plugging in the cable, check that the “▼” mark molded on the
connector or the colored stripe on the cable (indicating the location of Pin 1)
matches Pin 1 of the connector on the board.

Installing Your FlashPoint
2-6 FlashPoint™ LT BT-930 User’s Manual
Figure 2-3. Installing Internal Devices and Cables
When installing one internal device, connect it to the end of the cable and
terminate the device. Consult the owners manual for information on how to
terminate the device.
If a second internal device is to be included in the internal installation,
terminate only the device at the end of the cable. If the default configuration
for the device in the middle of the cable is terminated, consult the owner’s
manual to find out how to disable termination.
Be sure each device has a unique SCSI ID assigned. See “Setting the SCSI
Device ID” on page 2-2 in this chapter for more information about assigning
SCSI IDs.
Install the LED Cable (Optional)
Insert the connector from the drive activity LED on the front panel of the
host to the connector on the FlashPoint as shown in Figure 2-4. This
connector is reversible and may be plugged into the connector in either
direction. If your system has a two-pin LED drive activity connector, use the
first two or the last two pins. The following diagram shows the connector
pin-outs.
