Attach an antistatic wrist strap as described in Chapter 1, “Opening and Closing the Base Unit,” before opening the base unit.

Adding Main Memory

Single inline memory modules (SIMMs) must meet the following specifications:
Height Up to 1.4 inches high Type 72-pin, single- or double-sided EDO SIMMs Specifications 5 volt, 60 ns, 36 and 32 bit, tin-plated edge finger contacts
NOTE System memory modules available from Intergraph have been certified for use with
Intergraph computers at extremes of temperature and system load to ensure reliable performance. System memory modules available from other vendors may function improperly or unreliably in your Intergraph computer.
35
To avoid damaging the SIMMs and voiding the warranty, take the following precautions.
u
Do not bend, twist, drop, or otherwise handle the SIMMs carelessly.
u
Do not expose the SIMMs to moisture or extreme temperatures.
u
Do not remove the SIMMs from the antistatic bag until instructed.
Follow these SIMM population rules to correctly install the SIMMs.
u
Each bank has two slots. Fill both slots in a bank.
u
Use the same size SIMM in both slots in a bank.
u
Install SIMMs one bank at a time, beginning with bank 0 and ending with bank 3.
u
After adding or replacing SIMMs, restart the computer. The new memory configuration is detected automatically.
To install a memory upgrade:
1. Remove any option boards that interfere with access to the SIMM sockets.
2. Remove the existing SIMMs from their sockets before adding new ones. Refer to the
following figure.
36
Socket 3
Socket 2

4. Position the SIMM in the next available socket so that the notch faces the front of the
base unit.
5. Insert the SIMM at a 60 degree angle, pressing it firmly into the socket.
6. Push on the top edge of the SIMM until it snaps into the metal clips and locks into the
vertical position. The socket tabs must fit inside the mounting holes of the SIMM.
CAUTION Do not use a rocking motion as you install the memory module. Doing so might damage the
module, the socket, or both.
7. Repeat steps 5 through 7 for each SIMM.
8. Replace the option boards that you removed in step 1 above.
9. After you close the base unit, restart the system. The new memory is recognized
automatically.

Adding Internal SCSI Devices

Desktop systems are equipped with an Ultra SCSI controller for all SCSI devices.
u
You can install internal Ultra SCSI devices, or devices controlled from an expansion card, in the device bays located on the right front side of the base unit of a desktop system. The device must be 1.6 inches high or less to fit in these bays.
u
You can install a replacement or a second SCSI hard disk drive into the system hard disk drive bracket between the riser card and power supply. If the hard disk drive is more than 1 inch high, you will not be able to install a second hard disk drive into the system hard disk drive bracket, nor will you be able to use ISA slot 1. If you install a second hard disk drive in the system hard disk drive bracket, you will not be able to use ISA slot 1. If you install a non-Ultra SCSI device, data transfer rates are limited to the
device’s speed.
Deskside systems are equipped with an Ultra Wide SCSI controller for internal SCSI devices. The internal device bays are located above the floppy disk drive bay. You can install internal Ultra Wide SCSI devices, or devices controlled from an expansion card, in the device bays. The device bays are designed to accommodate 1.6-inch high devices; if a device is more than one 1.6-inch high, the bay underneath must be left empty. If you install a non-Ultra Wide SCSI device, data transfer rates are limited to the device’s speed.
CAUTION Connecting a non-compliant SCSI-1 device to a TD-x20, TD-x25, TDZ-x20, or TDZ-x25
workstation may cause your system to stop working, or lead to other unpredictable results.
To install an internal SCSI device:
NOTE Refer to Chapter 2, “Maintaining System Devices,” for information about removing and
replacing devices in the system, and for information on installing a device in the optional device bay on the desktop system.
37
1. If a device already occupies the location in which you are adding the new device, remove
the existing device. If installing the device into an empty drive bay, remove the support or slide bracket from the drive bay.
2. Mount the device to the support or slide bracket, if necessary.
3. If you are installing the device into one of the forward device bays in a desktop system,
slide the device through the faceplate and secure it to the chassis.
4. If installing hard disk drives into the system hard disk drive bracket in a desktop system,
replace the bracket, ensuring the bracket tabs engage the slots on the peripheral brace.
NOTE ISA Slot 1 can be used only if a single system hard disk drive is installed, and if it is less than
1.6-inches in height.
5. Connect the SCSI cable and power cable to the device. The SCSI cable is keyed to
ensure proper insertion, so that the red stripe (pin 1) is adjacent to the power connector.
38
Peripheral Brace
Power Connector
SCSI Cable Red Stripe
6. After closing the base unit, install the device drivers and configure the device according
to the vendor’s instructions, if necessary.

Adding External SCSI Devices

Desktop systems are equipped with an Ultra SCSI controller for all SCSI devices. If you install a non-Ultra SCSI device, data transfer rates are limited to the device’s speed.
Deskside systems are equipped with a separate Ultra SCSI controller for external SCSI devices. If you install a non-Ultra SCSI device, data transfer rates are limited to the device’s speed.
CAUTION Connecting a non-compliant SCSI-1 device to a TD-x20, TD-x25, TDZ-x20, or TDZ-x25
system may cause your system to stop working, or lead to other unpredictable results.
You can add up to five external single-ended SCSI devices to a desktop workstation, and up to seven external single-ended SCSI devices to a deskside workstation. The total length of the external SCSI cables depends on the number of devices connected to the SCSI adapter.
The total length must not exceed the following:
39
Devices
1 to 4 6 meters 3 meters 3 meters 5 to 8 3 meters 3 meters 1.5 meters
NOTE You must count the controller as one device.
When calculating the total length of the SCSI cables connected to the SCSI adapter, use the following estimates where appropriate:
SCSI cabling inside a desktop workstation 101.6 mm SCSI cabling inside each external device 203.2 mm
NOTE The last external device on the SCSI cable chain must supply active termination. All other
external devices must have SCSI termination disabled or removed.
To install an external SCSI device:
1. Set the device’s SCSI ID to an unused number and enable or disable the device’s SCSI
termination according to the note above and the vendor’s instructions.
2. Connect one end of the SCSI cable to the SCSI port on the back of the base unit. If
other external devices are installed, connect the SCSI cable to the available SCSI port on the last device on the SCSI cable chain.
3. Connect the new SCSI device to the other end of the SCSI cable.
4. If necessary, install the device drivers and configure the device according to the vendor’s
instructions.

Primary PCI Slots

Some PCI option boards must be installed in a primary PCI slot. Refer to the documentation delivered with the option board to determine if it must be installed in a primary PCI slot. The following are the primary PCI slots.
Desktop systems: PCI Slots 1, 2, 3 Deskside systems: PCI Slots 5, 6

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.
Setting jumpers on PCI IDE controller boards:
1. To install a PCI IDE controller board, you must first set the jumpers on the controller
board to coordinate the primary IDE channel with IRQ14. If the controller board is a dual channel board, set the jumpers to coordinate the secondary IDE channel with IRQ15 as well. Use the guide below when setting the jumpers.
Desktop Systems
IRQ14 IRQ15
PCI Slot 1 INT A INT B PCI Slot 2 INT D INT A PCI Slot 3 INT C INT D
Deskside Systems
IRQ14 IRQ15
PCI Slot 5 INT A INT B PCI Slot 6 INT D INT A
NOTE A PCI IDE controller board must be installed in a primary PCI slot.
2. Install the controller board according to the instructions that follow.
To install PCI option boards:
1. 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 in step 1 above.
e
4. After closing the base unit, restart the system. The new PCI board is recognized and
configured automatically.

ISA Option Boards

ISA boards require that specific system resources be reserved for their use. You can define and reserve these resources automatically if your operating system supports Plug-and-Play. Otherwise you can define and reserve these resources using the Setup options in BIOS Setup. Refer to the System Setup guide for more information.
To install an ISA board:
NOTE ISA Slot 1 can be used only if a single system hard disk drive is installed, and if it is less than
1.6-inches in height.
1. If installing the board onto side one of the riser card, remove the blanking plate from the
appropriate slot.
2. If installing the board to side two of the riser card, do the following:
In a desktop system, remove the system hard disk drive.
43
In a deskside system, disconnect the intervening cables from the riser card.
Remove the I/O lock bracket and the blanking plate, shown in the following figure.

PCI to ISA Bus Interrupt Mapping

The ISA bridge (Intel 82371SB) provides the sixteen conventional ISA interrupts, plus four interrupt request pins for PCI peripheral interrupts (PIRQ0 through PIRQ3). For PC-AT architecture compatibility reasons, the PCI interrupts are routed to the ISA interrupts within the ISA bridge. The assertion of a PCI interrupt concludes in an ISA interrupt being asserted.
Bit 7 of each PIRQ registers enable (Low) or disable (High) the routing of the PIRQ to an ISA interrupt. The lowest four bits (3:0) of each PIRQ register determines to which ISA interrupt the PIRQ will be routed. The PIRQs can be mapped to the following ISA interrupts:
IRQ 5, 9, 10, 11, 15
52
Each PCI slot on the riser card has four available interrupt lines: INTA, INTB, INTC, and INTD. These are connected to the PCI interrupts, PIRQ0 through PIRQ3, as shown below:
Interrupt Line
INTA PIRQ0 PIRQ1 PIRQ2 PIRQ3 PIRQ0 PIRQ1 INTB PIRQ1 PIRQ2 PIRQ3 PIRQ0 PIRQ1 PIRQ2 INTC PIRQ2 PIRQ3 PIRQ0 PIRQ1 PIRQ2 PIRQ3 INTD PIRQ3 PIRQ0 PIRQ1 PIRQ2 PIRQ3 PIRQ0

ISA Bus

The ISA slots on the riser card accommodate ISA based option boards and a 16-bit wide expansion bus. The ISA bus interrupt (IRQ) assignments are defined below.
IRQ
0 System Timer 8 Real Time Clock 1 Keyboard 9 H/W Monitor 2 Cascade input for IRQ8 - IRQ15 10 Open 3 COM2, COM4 11 Open 4 COM1, COM3 12 Mouse 5 Crystal CS4236B Controller 13 Floating Point Unit 6 Floppy Controller 14 IDE CDROM 7 Parallel Port 15 MIDI Port
Slot 1 Slot 2 Slot 3 Slot 4 Slot 5 Slot 6
Name IRQ Name
The spare interrupts listed above may be assigned to PCI and ISA devices. When you add a PCI device to the system, the interrupt will be automatically assigned by the system BIOS. However, at least one interrupt must be available for the PCI bus. For increased performance, one interrupt should be left available for each PCI based controller used in the system. When you add a ISA board, you must assign the interrupt using the System BIOS and jumpers on the option board.
The Sound Controller can be configured for either IRQs 5, 7, 9, 11, 12, or 15. The MIDI Port can be configured for either IRQs 9, 10, 11, 15, or no interrupt, in which case it will act as a write-only device.
