Adding PCI cards

The Workstation SDV has seven- (7) PCI slots as shown in Figure 9. To install a PCI add-in card, identify an empty PCI slot and insert the card into the slot. When the card is properly seated, press the card into the slot until it is firmly in place.

Removing the Memory Board

To add or remove memory, each memory board must be removed from the baseboard connector. Remove a memory board by first pulling back the two- (2) ejector clips on the board (Refer to Figure 9). Then slide the board out of the connector and the retention mechanism.

To reinsert the memory board, align it with the guides in the retention mechanism and slide it forward. Once the board is aligned with the connector on the baseboard, press down on the ejector clips until firmly in place.

Figure 9. PCI Slots and Memory Boards

Adding Memory

The Workstation SDV uses PC100 compliant 168-pin (x72) DIMMs. Functionally, 16-Mb, 64-Mb, 128-Mb and 256-Mb SDRAM devices are supported, but the 16-and 64-MB devices will not be validated on the system. The following steps take you through the DIMMs installation procedure (Refer to Figure 10):

After removing the memory board, locate the DIMM slots.

Holding the DIMM by its edges, remove it from its anti-static package.

Ensure that the clips at either end of the socket are pushed away from the socket.

Position the DIMM above the socket and align the two- (2) small notches in the bottom-edge of the DIMM with the keys in the socket.

Insert the bottom-edge of the DIMM into the socket.

When the DIMM is seated, press down on the top-edge of the DIMM until the retaining clips at the ends of the socket snap into place.

Make sure that the clips are firmly in place.

Figure 10. Adding Memory

Removing Memory

The procedure for removing memory follows:

After removing the memory board, locate the DIMM slots.

Gently spread the retaining clips at each end of the slots.

The DIMM will pop out of the socket.

Hold the DIMM by its edges, lift away from the slot and store in an anti-static package.

Valid Memory Configurations

The system can operate with one- (1) to two- (2) memory boards installed. However, to gain maximum memory bandwidth, both boards must be used. Each board has eight- (8) DIMM sites. The top four- (4) DIMMs form the top or right stack while the bottom four- (4) DIMMs form the bottom or left stack (on each of the two boards). The chipset allows multiple rows per stack, but on this system there is only one- (1) row per stack. The DIMMs within a row must be of the same size, type and must be manufactured by the same vendor. The DIMMs must always be installed in groups of four- (4).

Figure 11. Memory Board Stacks

If a single memory board is used, a minimum of four- (4) DIMMs must be populated in the top stack. If eight- (8) DIMMs are used, they can be on the same memory board in the top and bottom stacks. However, to get the maximum bandwidth with eight- (8) DIMMs, both boards should be used. The top stacks on each of the two- (2) memory boards should be populated using four- (4) DIMMs.

. NOTE

The bottom stack in the Workstation SDV has not been activated at this time.

Processor Overview

The Itanium™ processor is the first in a series of high-performance Intel 64-bit processors. Intel’s 64-bit Instruction Set Architecture (ISA) is referred to as IA-64. IA-64 maintains full compatibility with Intel’s current 32-bit Intel Architecture processor family while delivering industry-leading performance beyond existing architectures.

Each Itanium™ processor is packaged in a PAC418 (418-pin array cartridge) format. The cartridge includes:

The processor core

16 KB L1 instruction cache

16 KB L1 data cache

Unified L2 cache

Unified L3 cache

A thermal plate

/ NOTE
Each processor implements the MMX™ and SSE (Streaming SIMD Extensions) technology.

Memory Overview

Main memory resides on two- (2) add-in boards called Memory Expansion Cards (MECs). Each MEC contains slots for eight- (8) DIMMs and two- (2) connectors for DC-DC converters and is attached to the baseboard through a 300-pin connector. The memory controller supports PC100-registered SDRAM DIMMs. The Workstation SDV is provided with eight- (8), 128-MB DIMMs for a total of 1 GB of memory.

/ NOTE

DIMMs must be installed in groups of four- (4) with all DIMMs within a row being of the same size, type and manufacturer. For optimum performance, the rows must also be populated in the proper order with the same size of DIMMs. Depending on how the memory modules are installed, the memory subsystem can operate in two- (2) different modes; interleaved and single-port.

Interleaved Mode: (two- [2] MECs installed). This configuration offers the highest performance because it allows the two- (2) modules to be used in a balanced fashion, reducing address conflicts. To operate in interleaved mode, the DIMMs MUST BE INSTALLED IN THE TOP FOUR- (4) DIMM SITES ON EACH MEC. BOTH MECs MUST BE INSTALLED.

Single-port Mode: (one MEC installed). The single MEC responds to all memory addresses.

DIMM Installation Sequence

A single MEC supports a DIMM population in various configurations (empty sockets included). However, the DIMMs must be installed within groups of four- (4). For optimum performance, both memory cards should be installed with the top four- (4) DIMM slots populated with the same size, type and brand of memory. This recommendation utilizes both memory ports and achieves maximum memory bandwidth. The minimum memory configuration is illustrated in Figure 13.

Figure 13. Memory Expansion Card

/ NOTE

Maximum capacity is limited to 16 GB with two- (2) memory cards installed (using 1 GB DIMMs). However, this configuration has not been validated.

/ NOTE

DIMM sizes and compatibility: Use DIMMs that have been tested for compatibility. (Refer to Table 6.)

It executes only under EFI shell version 0.91 or higher (type "ver" in the EFI shell to check the version number).

Copy the IFlash.efi and binary input file to an LS-120 disk*

Boot to EFI shell and change to the LS-120 (e.g., if LS-120 is device fs0 then type "FS0:" and hit ENTER)

Enter the following command (and follow the instructions on the screen) Iflash64 <filename> /a=0

Additional information can be obtained via the utility help command Iflash64 /h

Reboot the system after the update is completed.

NOTE

Use a newly formatted disk.

Recovering the BIOS

The BIOS recovery feature is not available on Workstation SDV systems.

Language Support

Only American English is supported on the Workstation SDV systems.

Boot Options

SCSI HDD Boot is available.

Post Codes

During the POST, the BIOS utility generates diagnostic progress codes (POST-codes) to I/O ports 80h and 81h. If the POST fails, execution stops and the last POST-code generated is left at ports 80h and 81h. These codes are useful for determining the point where an error occurred.

Displaying the POST-codes requires an add-in card (often called a POST card). The POST card can decode the port and display the contents on a medium such as a seven-segment display.

Refer to Table 8 for descriptions of the POST-codes generated by the BIOS.

POST Codes Testing Phase

BIOS indicates the current testing phase during POST after the video adapter has been successfully initialized by outputting a 2-digit hex code to I/O location 80h. To view POST-codes, you must install an optional PCI POST add-in board. For more information, contact your designated Intel or Premier Support Site representative.

/ NOTE

Port 0x81 of the POST-codes is currently only used for debug purposes.

5 Solving Problems

This chapter helps you identify and solve problems that might occur while you are using the beta Workstation SDV system.

Resetting the System

To do this:	Press:
Soft boot reset, which clears system memory and reloads the operating system.	<Ctrl+Alt+Del>
Cold boot reset, which clears system memory, restarts POST, and initializes halts power to all all peripherals. Hold the power button for 4 seconds to Power off. Hard reset, which also clears system memory, restarts POST, and initializes all peripherals.	Power off/on Press the reset switch located on a card slot filler panel at the rear of the system

Initial System Startup

Incorrect installation or configuration usually causes problems that occur at initial system startup. Hardware failure is a less frequent cause.

Startup Checklist

Are the processors fully seated in their connectors on the processor board?

c Is at least one- (1) memory board installed and fully seated?

Are all add-in PCI boards fully seated in their slots on the baseboard?
Are all switch and jumper settings on boards and drives correct?
Are all switch and jumper settings on add-in cards and peripheral devices correct? To check these settings refer to the manufacturer’s documentation that comes with them. If applicable, ensure that there are no conflicts - for example, two- (2) add-in cards sharing the same interrupt.
Are all DIMMs installed correctly?
Are all peripheral devices installed correctly?
Is the hard disk drive properly formatted or configured?

Are all device drivers properly installed?
Did you press the system power on/off switch on the front panel to turn the system on (power-on light should be lit)?
Are the system power cords properly connected to the system and plugged into an outlet for 110-240 VAC?
Is AC power available at the wall outlet?

Monitoring POST

Review the Post-code section that starts on page 38 again, before proceeding.

/ NOTE

A Post card is required to view POST- codes.

Verifying Proper Operation of Key System Lights

As POST determines the system configuration, it tests for the presence of each mass-storage device installed in the system. As each device is checked, its activity light should turn on briefly.

Check for the following:

Does the diskette drive activity light turn on briefly? If not, see "LS-120 Drive Activity Light Does Not Light" on page *.

Does the hard disk drive activity light on the control panel turn on briefly? If not, see "Hard Disk Drive Activity Light Does Not Light" on page *.

Network Problems

If you have network problems, consult the documentation for the D101 Ethernet card that was supplied with the system.

PCI Installation Tips

Some common PCI installation tips:

Certain drivers may require interrupts that are not shared with other PCI drivers. For certain drivers, it may be necessary to alter settings so that interrupts are not shared.

Check PCI interrupt interdependencies among slots and onboard devices.

/ NOTE

PCI peripherals will not operate if used with IA-32 drivers. At this time, there are a limited number of drivers available for IA-64 PCI peripherals, do not install any additional PCI peripherals that do not have current IA-64 drivers.

Error and Informational Messages

When you turn on the system, POST displays messages that provide information about the system.

Reserved pins are only for future use by the AGP specification.

IDSEL# is not a pin on the AGP connector. AGP graphics components should connect the AD16 signal to the 3. 3 volt IDSEL# function internal to the component.

All 3.3 V cards leave the TYPEDET signal open. All 1.5 V cards tie the signal hard to ground.
