About the System’s Video Display

When you start your system for the first time, it uses the Windows NT
Workstation VGA display driver to run the video display. To enable your
system to use its installed GLZ video display adapter, you must configure the
video display to use the Intergraph GL video display driver. This driver is

installed on the system’s hard disk, and is also delivered on a backup
diskette.

The Intergraph GLZ video display adapter is a 3D graphics accelerator.
GLZ provides a number of advanced graphics features, including hardware
acceleration of OpenGL and Windows NT graphics operations. GLZ is
available in several configurations, as follows:

♦ GLZ1 -- 12 MB of frame buffer memory, resolutions up to 1 megapixel

(1152 x 864).

♦ GLZ1T -- same features as GLZ1, with support for texture mapping.

♦ GLZ2 -- 24 MB of frame buffer memory, resolutions up to 1600 x 1280.

♦ GLZ3 -- same features as GLZ1, with support for geometry acceleration.

♦ GLZ4 -- same features as GLZ2, with support for geometry acceleration.

♦ GLZ5 -- same features as GLZ3, with support for texture mapping.

♦ GLZ6 -- 34 MB of frame buffer memory, hardware-accelerated support

for texture mapping and geometry acceleration, resolutions up to 1600 x

1280.

If your system is set up for dual-screen display, the video display driver
treats the combined display area of the dual screens as a single canvas that
covers both screens. In this Full Canvas style, windows centered on the
canvas are split between the two screens. This includes most system dialog
boxes.

When the system is running Windows NT Workstation 3.5 (or later), the
video display driver can treat the left or top monitor as the primary screen,
while the full desktop extends across both screens. This Primary Left/Top
style results in different windowing behaviors than those displayed by
default, including the following:

Chapter 2 - Configuring the System 17

♦ Dialogs display fully and applications maximize on the primary screen.

♦ Most centered windows center on the primary screen.

♦ Testing a dual-screen mode from the Display Properties application

actually tests only the corresponding single-screen mode.

♦ Toolbars may not use the whole desktop.

♦ Screen savers may work only on the primary screen.

To select a dual-screen style, refer to the configuration instructions for the
GL video display driver later in this chapter.

Configuring the Video Display

Use Intergraph’s Video Configuration application in the Windows NT
Control Panel to change the configuration of the GL video display driver.
The Video Configuration application controls basic and advanced display
attributes of the GL video display driver.

Note: Windows NT provides a Display application in the Control Panel for

changing the video display. Use the Video Configuration
application instead of the Windows NT Display application to
configure the GL display driver on your system.

Reprogramming the Flash EPROM

You can use the Flash Programming Utility (FPU) to reprogram the system
board flash EPROM with a new BIOS. When run, the FPU first looks on the
diskette in the floppy disk drive for a valid BIOS. Therefore it is best to save
the BIOS file and the FPU (available on the IBBS) to the System Utilities
(SYSUTIL) diskette.

Note: The desktop workstations use the 741XX.ROM BIOS, where XX is

the version number.

The FPU is an MS-DOS utility that will not run in the Windows NT
environment. Use the SYSUTIL diskette delivered with your system to boot
the system into MS-DOS. The system must be set to boot from the floppy
disk drive (normally drive A) to use these utilities. If necessary, refer to

“Changing the System Boot Sequence.”

To reprogram the flash EPROM:

➤

1. Connect to the Intergraph Bulletin Board Service (IBBS) via modem.
Refer to the “Preface” for instructions.

2. From the TOP menu, go to Intergraph Product Centers, Systems and
Networking, File Libraries, and Delivered Drivers; then, select the
appropriate operating system and hardware platform.

3. Choose Find File to search for the FLASHPROG product; then,
download FLASHPROG to your system.

PCI Option Boards

PCI boards do not require manual system configuration when installing the

board. The system BIOS detects the board’s presence during startup and
reads information from the board’s configuration registers to assign the
necessary system resources.

To install PCI option boards:

➤

1. Using a quarter-inch nutdriver, remove the blanking plate from an
available PCI slot.

2. Install the PCI board. Press firmly to ensure the board seats
completely into the riser card connector.

3. Mount the board to the chassis using the screw removed previously.

Chapter 5 - Upgrading the System 63

4. Close the base unit.

5. Restart the system. The new PCI board is recognized and configured
automatically.

ISA and PnP Option Boards

ISA boards are not designed with internal registers that define the board’s
configuration to the system during startup. Therefore, you must run the
System Configuration Utility (SCU) to define the board to the system. Run
the SCU before installing an ISA board to reserve system resources for the
board and to prevent conflicts with option boards already installed. Refer to
“Using the System Configuration Utility” in this chapter.

PnP boards are ISA boards that contain configuration registers like PCI
boards. You do not have to run the SCU to define a PnP board. During
startup, the system BIOS automatically detects the installed board and
assigns the necessary system resources. Since PnP boards are ISA-based
boards, they can be installed in the same slots as ISA boards..

Note: Only half-length ISA and PnP boards may be installed in the ISA

slots.

To install ISA and PnP boards:

➤

1. Remove the auxiliary hard disk drive (or its bracket if the disk drive is
not installed).

2. If installing the board onto side one of the riser card, use a quarter­inch nutdriver to remove the blanking plate from the ISA slot.

64 Chapter 5 - Upgrading the System

3. If installing the board to side two of the riser card, remove the I/O
lock bracket and the blanking plate from the destination slot.

Using AMIBIOS Setup

The Basic Input/Output System (BIOS) records the system operating
parameters, such as the amount of memory, boot sequence, and the type of
video display. The system parameters are set before shipment. The BIOS,
which is stored in the flash EPROM on the system board, reads the system
parameters in Complementary Metal-Oxide Semiconductor (CMOS) RAM.
When you power off the system, the lithium source on the Real-Time Clock
chip provides power to CMOS RAM, which retains the system parameters.
Each time the system is powered on, the BIOS uses the stored system
parameters to configure the system.

Note: The flash EPROM can be reprogrammed with a new BIOS using the

Flash Programming Utility (FPU). Refer to Chapter 4, “Maintaining

the System,” for instructions on using the FPU.

79

The AMIBIOS Setup program allows you to manually change the system
operating parameters. This chapter provides the details of using the
AMIBIOS Setup program, which is also stored in the flash EPROM on the
system board.

The AMIBIOS Setup menus and options discussed in this chapter are for
BIOS 741XX.ROM, where XX is the version. The BIOS version number is
displayed during the American Megatrends, Inc., banner message during
boot up. The banner message is similar to the following:

ISA Video ROM C000, 32K -- ROM shadowing is a procedure in which

BIOS code is copied from ROM to RAM when the system boots. When set
to Enabled (default) the BIOS then executes from RAM, providing faster
access time and improving system performance.

ISA Adapter ROM XXXX, 16K -- For ISA boards that contain a BIOS on

ROM, this parameter (when set to Enabled) allows you to tell the ISA board
BIOS to be copied from the ISA board ROM to system board RAM. An ISA
board BIOS executes faster from system board RAM than from the ISA
board ROM. All of the ISA Adapter ROM parameters are set to Disabled by
default.

Chipset Setup

The Chipset Setup menu contains the parameters that affect the functionality
of some hardware components.

Sound, IO Port Select -- This parameter allows you to select the I/O base

and MP-401 addresses used by the sound subsystem. The default is 220/330.
The other choices are 240/300 and Disabled. When set to Disabled, the
DMA and IRQ addresses for the next three sound parameters are no longer
reserved. These DMA and IRQ addresses can then be used for other
resources.

Sound, 8-bit DMA Select -- This parameter allows you to select the 8-bit

DMA used by the sound subsystem. The default is DMA1. The other
choice is DMA3.

Sound, 16-bit DMA Select -- This parameter allows you to select the

16-bit DMA used by the sound subsystem. The default is DMA5. The other
choice is DMA7.

Sound, IRQ Select -- This parameter allows you to select the IRQ used by

the sound subsystem. The default is IRQ10. Other choices are IRQ5 and
IRQ7.

PCI VGA Buffering -- The PCI VGA Buffering parameter allows you to

implement the read prefetch support in the linear buffer of the workstation
graphics hardware. System performance increases when set to Enabled
(default). If you install a graphics card that does not support read prefetch,
this parameter must be set to Disabled for proper display.

PCI VGA Palette Snooping -- This parameter allows palette data from an

installed PCI graphics board to be shared with an installed ISA graphics
board. Since the graphics delivered with the workstation are PCI-based, this
option is set to Disabled by default.

Primary PCI SCSI -- This parameter activates the PCI-based SCSI

controllers on the mother board when set to Enabled (default). The SCSI
controllers can be disabled by changing the value to Disabled.

Operating System Boot Device -- This parameter specifies which

controller the BIOS will attempt to boot from first. The device that you
specify to be the boot device will be assigned to drive C. By default, drive C
is the system hard disk drive. Refer also to the System Boot Up Sequence

parameter in “Advanced Setup.”

Boot to PnP Operating System -- When this parameter is set to No

(default), the BIOS will initialize all devices during boot up. When set to
Yes, the BIOS only performs the amount of initialization required to load the
operating system. Any other device initialization must then be performed by
the operating system.

Installed Memory Speed -- The workstations use 70 ns memory SIMMs,

so this parameter is set to 70 ns by default. The other choice is 60 ns, which
should not be used. The system will not boot if you set this parameter to 60
ns.

Peripheral Setup

The Peripheral Setup menu has parameters that affect option boards, serial
ports, and parallel port functionality.

Programming Mode -- This parameter detects all installed option boards

and configures the on-board components accordingly. When set to Auto
(default), the system BIOS automatically detects the installed option boards
during boot up. When set to Manual, the next four parameters, plus Parallel
Port IRQ, activate.

OnBoard FDC -- When set to Enabled (default), this parameter enables the

system I/O controller on the system board. If you install floppy controller
cards, then this parameter must be set to Disabled.

Serial Port1 -- This parameter enables the use of serial port 1 on the system

board by selecting a memory address for the port. The values are Disabled,
3E8H, 3F8H (default), 2E8H. The addresses correlate to a COM port
number as defined by the following table.

Serial Port Addresses Interrupts

COM1 3F8-3FF IRQ4
COM2 2F8-2FF IRQ3
COM3 3E8-3EF IRQ4
COM4 2E8-2EF IRQ3

Serial Port2 -- This parameter enables the use of serial port 2 on the system

board by selecting a memory address for the port. The values are Disabled,
3E8H, 2F8H (default), 2E8H. The addresses correlate to a COM port
number as defined by the serial port table above.

Parallel Port -- This parameter enables the use of the parallel port by

selecting a memory address. The values are Disabled, 278H, 378H (default),
and 3B8H. The addresses correlate to an LPT port number as defined by the
following table.

Parallel Port Address Interrupt

LPT1 378-37A IRQ7 or IRQ5
LPT2 278-27A IRQ7 or IRQ5
LPT3 3BC-3BE IRQ7 or IRQ5

Parallel Port Mode -- This parameter allows you to change the parallel

port mode setting. The values are Normal, Bi-Dir, EPP (default), and ECP.
When set to ECP, the ECP DMA Channel parameter activates.

Parallel Port IRQ -- This parameter allows you to select a base IRQ for the

parallel port. The default is IRQ-7, or IRQ-5 may be selected. Either IRQ
can be assigned to any of the LPT port numbers as shown in the parallel port
table above.

ECP DMA Channel -- This parameter activates when the Parallel Port

Mode is set to ECP. You can select a DMA channel for the parallel port

86 Chapter 7 - Using AMIBIOS Setup

when operating in ECP mode. Values for this parameter are None, CH 1
through CH 7. When the Parallel Port Mode is set to ECP, the default DMA
channel is 5.

Security Menu

The Security Menu allows you to change the system password and enable or
disable virus protection.

Password
