Chapter 1 Hardware Installation

Step 1 Unpack the Motherboard

Step Action

1 Inspect the cardboard carton for obvious damage. If damaged, call 770-

246-8600. Leave the motherboard in its original packing.

2 Perform all unpacking and installation procedures on a ground-

connected anti-static mat. Wear an anti-static wristband grounded at the same point as the anti-static mat. Or use a sheet of conductive aluminum foil grounded through a 1 megohm resistor instead of the anti-static mat. Similarly, a strip of conductive aluminum foil wrapped around the wrist and grounded through a 1 megohm resistor serves the same purpose as the wristband.

3 Inside the carton, the motherboard is packed in an anti-static bag, and

sandwiched between sheets of sponge. Remove the sponge and the anti-static bag. Place the motherboard on a grounded anti-static surface component side up. Save the original packing material.

4 Inspect the motherboard for damage. Press down on all ICs mounted in

sockets to verify proper seating. Do not apply power to the motherboard if it has been damaged.

5 If the motherboard is undamaged, it is ready to be installed.

Set Jumpers Set all jumpers and install the CPU before placing the

motherboard in the chassis.

Avoid Static Electricity

Static electricity can damage the motherboard and other computer components. Keep the motherboard in the antistatic bag until it is to be installed. Wear an anti-static wrist grounding strap before handling the motherboard. Make sure you stand on an anti-static mat when handling the motherboard.

Avoid contact with any component or connector on any adapter card, printed circuit board, or memory module. Handle these components by the mounting bracket.

MegaRUM II PCI Motherboard User’s Guide

Step 2 Configure CPU Speed

If using two CPUs with different speed ratings, set the motherboard jumpers to the lower CPU speed. When JP6 is open, the system bus frequency is determined by the processors. When JP6 is shorted, the system bus frequency is forced to be 66 MHz.

Step 3 Install Additional Voltage Regulator

One Voltage Regulator Module (VRM) is shipped with every MegaRUM II motherboard. You need another VRM if you install two CPUs. You can order VRMs for Intel Pentium II CPUs from:

Manufacturer Part Number AMI Part Number

VXI 073-20740-20 MDL-PII-V5A190

Step 4 Connect CPU Fans

JP1 and JP2 (shown below) are 3-pin bergs that connect the fan on the CPU heat sink to the motherboard power. JP1 is the CPU fan connector for the CPU in CPU Slot1. JP2 is the CPU fan connector for the CPU in CPU Slot2.

All Pentium II CPUs are shipped with a heat sink and a CPU fan.

JP1 and JP2 are keyed in such a way that the CPU fan connector can only be attached in the correct manner.

The connector from the CPU fan usually has three leads (red, yellow, and black leads).

JP19, JP18 System Fan JP19and JP18 are 3-pin bergs. The pinout is the

same for JP19 and JP18 as it is for JP1 and JP2. JP19 and JP18 provide +12V power to the main chassis fan. The chassis fan should provide a tachometer output on Pin 3 so it can be monitored by the onboard server management hardware.

MegaRUM II PCI Motherboard User’s Guide

Step 5 Install CPU

The Pentium II CPUs are on Intel Slot1 adapter cards. Insert the Slot1 cards into the CPU card sockets on the motherboard. See the motherboard drawing on page 3 for the location.

The CPU Slot1 sockets are below the SDRAM sockets, as shown on page 3.

Warning

Improper CPU installation can damage the CPU and the

motherboard. You must follow the procedures in this

section exactly as documented. Make sure you wear an

antistatic wristband while installing the CPU. Follow all

antistatic procedures described on page 4.

Termination Card The MegaRUM II motherboard is shipped with a

termination card that should be installed in the empty CPU slot if only one CPU is installed.

You must install the termination card in the empty CPU slot if installing only one Pentium II CPU. The motherboard will not power up unless both CPU slots are occupied. The CPU slot where the termination card is installed does not require a VRM.

Step 6 Install Memory

System Memory There are four 72-bit SDRAM DIMM (Dual Inline

Memory Module) sockets. System memory must be populated one bank at a time. Each bank has one socket.

The minimum amount of system memory supported by the MegaRUM II PCI is 8 MB. Each socket can hold one DIMM. You can use:

• 1 MB x 64 (or 72),

• 2 MB x 64 (or 72),

• 4 MB x 64 (or 72),

• 8 MB x 64 (or 72),

• 16 MB x 64 (or 72),

• 32 MB x 64 (or 72), or

• 64 MB x 64 (or 72).

Fast Page Mode and EDO SIMMs cannot be mixed in the same memory bank.

The MegaRUM II motherboard will support 128 MB SIMMs when they become available, permitting up to 2 GB of system memory to be installed on the motherboard. The motherboard supports SDRAM DIMM operating at 10 or 12 ns (RAS access time).

Memory Display System memory is reported by AMIBIOS as it boots and

again when the AMIBIOS System Configuration Screen is displayed just before the operating system boots. The memory displayed by AMIBIOS on the System Configuration Screen is 384 KB less than the total memory installed.

Step 10 Connect SCSI I/O

SCSI Connectors J18 (SCSI channel 1) and J17 (SCSI channel 2) are 68-

pin high density (Wide) SCSI connectors.

High Density SCSI Connectors The 68-pin high density connectors are

0.050” pitch unshielded connectors. The high-density connector pinouts are shown below:

These connectors provide all signals needed to connect to wide SCSI devices. The connector pinouts are for a singleended primary bus (P-CABLE) as specified in SCSI-3 Parallel Interface X3T9.2, Project 885-D, revision 1.2b, date July 2, 1993.

The cable assemblies that interface with this 68-pin connector are:

• flat ribbon or twisted pair cable for connecting

internal wide SCSI devices,

• flat ribbon or twisted pair cable for connecting

internal and external wide SCSI devices,

• cable assembly for converting from internal wide

SCSI connectors to internal non-wide (Type 2) connectors,

• cable assembly for converting from internal wide to

internal non-wide SCSI connectors (Type 30), and

• cable assembly for converting from internal wide to

internal non-wide SCSI connectors.

Single-Ended Ultra SCSI Understanding the cable requirements,

termination and stub lengths is key to the successful implementation of a Ultra-SCSI subsystem.

SCSI Cables - Up to Four Devices The total external SCSI cable length

for single-ended when using up to 4 Ultra-SCSI devices (maximum. capacitance of device = 25pf) should be less than or equal to:

(3 meter-(SCSI signal length on AMI RAID)-(SCSI length in storage

box) = (3 meter - 0.305 meter - SCSI length in storage box) = 2.695 - SCSI length in storage box

SCSI Cables - More than Four Devices The total external SCSI cable

length for single-ended when using from five to eight Ultra-SCSI devices (max. cap of device = 25pf) should be less than or equal to:

(1.5 meter-(SCSI signal length on AMI RAID)-(SCSI length in storage box)

= (1.5 meter - 0.305 meter - SCSI length in storage box)

= 1.195 - SCSI length in storage box

Spacing Devices The SCSI devices should be uniformly spaced between

terminators with the end devices located as close as possible to the terminators.

SCSI Signal Path The SCSI signal path is a controlled impedance

environment with the following characteristic impedance:

90 ohms +/- 6 ohms for the REQ and ACK signals

90 ohms +/- 10 ohms for all other signals

Cont’d

MegaRUM II PCI Motherboard User’s Guide

Step 10 Connect SCSI I/O, Continued

SCSI Termination The SCSI channels on the MegaRUM II motherboard

use active termination for each SCSI channel. You must terminate the SCSI bus properly. The SCSI bus on each SCSI channel is an electrical transmission line and it must be terminated properly at both ends to minimize reflections and losses. You complete the SCSI bus by setting termination at both ends.

Do not add terminators in the middle of the SCSI bus. The end devices must be located as close as possible to the terminators. A simple rule is to place SCSI terminator after the last SCSI device on each of the SCSI connectors. MegaRUM II automatically terminates the onboard SCSI connectors.

Stub length The stub length shall not exceed 0.1 meter. The spacing of

devices on the SCSI bus should be at least three times the stub length to avoid stub clustering.

SCSI Cables Teflon flat ribbon cables give the best performance in the

Ultra-SCSI environment. These cables should be used for all internal cabling. To minimize discontinuities and signal reflections, the use of cables with different impedance’s on the same bus should be minimized.

Setup using two connectors for one channel

If the MegaRUM II is at one end of a cable, it sets termination automatically at that end. Otherwise, MegaRUM II disables its own termination and you must set termination at the cable ends. If another connector on MegaRUM II is also used for the same channel, the termination on MegaRUM II is disabled automatically and termination should be set on the device at the farthest end of the cable.

For a disk array, set SCSI bus termination so that removing or adding a SCSI device does not disturb termination. An easy way to do this is to connect MegaRUM II at one end of the SCSI cable for each channel and to connect an external terminator module at the other end of each cable. The connectors between the two ends can connect SCSI devices. Disable termination on the SCSI devices. See the manual for each SCSI device to disable termination.

Chapter 1 Hardware Installation

Step 12 Test and Configure

Review the following points before powering up:

• make sure that all adapter cards are seated properly,

• make sure all connectors are properly installed,

• make sure the CPU is seated properly,

• make sure there are no screws or other foreign

material on the motherboard,

• plug the system into a surge-protected power strip,

and

• make sure blank back panels are installed on the back

of the chassis to minimize RF emissions.

Start the Test Plug everything in and turn on the switch. If there are any

signs of a problem, turn off the unit immediately. Reinstall the connectors. Call Technical Support if there are problems.

BIOS Errors If the system operates normally, a display should appear

on the monitor. The BIOS Power On Self Test (POST) should execute.

If POST does not run successfully, it will beep or display error messages. Beeps indicate a serious problem with the system configuration or hardware. The Beep Code indicates the problem. AMIBIOS Beep Codes are defined in the AMIBIOS Technical Reference. Make sure the affected part is properly seated and connected. An error message is displayed if the error is less serious. Recheck the system configuration or the connections.

Configure the System Run AMIBIOS Setup. You must enter the requested

information and save the configuration data in NVRAM. The system will then reset, run POST, and boot the operating system. See the following chapter for information on configuring the computer.

MegaRUM II PCI Motherboard User’s Guide

2 AMIBIOS Setup

In ISA and EISA computers, the system parameters (such as amount of memory, type of disk drives and video displays, and many other elements) are stored in CMOS RAM. Unlike the DRAM (dynamic random access memory) that is used for standard system memory, CMOS RAM requires very little power. When the computer is turned off, a back-up battery provides power to CMOS RAM, which retains the system parameters. Every time the computer is powered-on, the computer is configured with the values stored in CMOS RAM by the system BIOS, which gains control when the computer is powered on.

The system parameters are configured by a system BIOS Setup utility. Historically, BIOS Setup utilities have been character-based, required keyboard input, and have had user interfaces that were not very intuitive.

Starting AMIBIOS Setup As POST executes, the following appears:

3 Programming Flash ROM

All versions of the MegaRUM II PCI motherboard use Flash EPROM to store the system BIOS. The advantage of Flash EPROM is the EPROM chip does not have to be replaced to update the BIOS. The end user can actually reprogram the BIOS, using a ROM file supplied by American Megatrends.

Programming the Flash EPROM

Step Action

1 Turn power off. Make sure the computer has a working speaker. 2 Insert the floppy disk with the S774P.ROM file in drive A:. 3 Press and hold the <Ctrl> and <Home> keys down while turning the

power on. Continue to hold the <Ctrl> and <Home> keys down until the access light on the floppy drive comes on. It may take 10 seconds or more before this light turns on.

Since MegaRUM II uses a 2 megabit BIOS, the flashing process may take up to 3 minutes.

4 Release the <Ctrl> and <Home> keys. AMIBIOS issues a series of beep

codes that indicate that the system BIOS ROM file is being updated.

5 When the flash ROM has successfully been programmed, the computer

will reboot.

6 When the computer reboots, check the BIOS Release text at the bottom

of the first boot screen to make sure that the correct BIOS has been used.

7 The error message

NVRAM checksum bad, NVRAM cleared

will appear during the first boot after a successful BIOS ROM update. This message indicates that the NVRAM area in the system BIOS has been cleared. AMIBIOS will reconstruct the NVRAM area before the computer boots completely, so you can safely ignore this message.

A:. 2 Erases the Flash EPROM. 3 Programs the Flash EPROM with the data read from the floppy disk in

drive A:. 4 Generates a CPU reset, rebooting the computer.

The bootblock part of the Flash EPROM is not programmed. Should you inadvertently open the disk drive door or turn power off to the computer while programming the Flash EPROM, the bootblock will be unaffected. Simply turn power back on and begin the Flash ROM programming process again.

S774P.ROM S774P.ROM resides on a floppy disk and contains the

updated main BIOS code. American Megatrends will provide this file when the AMIBIOS for the MegaRUM II PCI ISA motherboard must be updated.

S774P.ROM must be present in the root directory of the floppy disk before the onboard Flash EPROM can be reprogrammed. The file that has the main BIOS code must be named S774P.ROM.

4 Deleting a Password

If you forget the passwords you set up through AMIBIOS Setup, the only way you can restart the computer is to erase the system configuration information where the passwords are stored. System configuration data is stored in CMOS RAM, a type of memory that consumes very little power.

Erase Old Password You can drain CMOS RAM power via J35 on the

motherboard. J35 is a 2-pin berg that is normally always OPEN. Perform the following steps to erase the old password.

Important

Make sure you are properly grounded before

performing the following procedure. You must be

certain that no electrostatic discharge (ESD) occurs.

ESD can ruin your motherboard. Wear an antistatic

wristband attached to a ground. See “Avoid Static

Electricity” on the following page.

Step Action

1 Turn the computer power off and remove the computer cover. 2 Place a shorting bridge on J35. 3 Turn on computer power for about 10 seconds. 4 Turn the computer off again. 5 Remove the shorting bridge from J35. 6 Turn on computer power again.

Since you drained power from CMOS RAM, all system configuration information has been erased. You must now re-enter the system configuration information by running AMIBIOS Setup.

Chapter 4 Deleting a Password 75

Avoid Static Electricity

Avoid contact with any component or connector on any adapter card, printed circuit board, or memory module. Handle these components by the mounting bracket.
