Installing CPU Boards

This section provides information on CPU boards for your server.

Types of CPU Boards

The system board has one CPU board slot that supports these two types of CPU boards:

• CPU board that supports the Intel Pentium™ processor

• CPU board that supports the Intel Pentium Pro™ processor

Installation

If you ordered a CPU board factory-installed, you may skip this chapter. If you must install a CPU board in your system, read all of this information.

When actually performing the installation, refer to the following documents for information on installing CPU boards in the system:

Installing CPU Boards

• Quick Hardware Installation that came with your system

• Release Notes that came with your CPU board

• Figure 2-7 in Chapter 2 of this manual for the location of the CPU board

slot on the system board

Warnings

When installing CPU boards, do not attempt to make any hardware changes unless you are a qualified technician. Ask your dealer for assistance.

There are two released versions of system BIOS. One is for the CPU board that supports the Pentium processor. The other is for the CPU board that supports the Pentium Pro processor. These versions of BIOS are not interchangeable. Flashing the incorrect version renders the system unusable.

NCR S26 Hot Plug Server User Guide 3-3

Installing CPU Boards

For example, if you flash the BIOS version released for a Pentium CPU board on a system configured with a Pentium Pro CPU board you cannot use the system. If this happens, you must insert the appropriate CPU board into the system and reflash the original BIOS.

Refer to the diskette label to make sure you are using the appropriate BIOS for your system configuration.

3-4 Adding and Replacing Components

Upgrading the Memory

You can upgrade the system memory by adding single inline memory modules (SIMMs) into the SIMM sockets or by changing the SIMMs for a higher memory configuration.

The configurations in Table 3-1 are only some of the available memory combinations. You can use other combinations if you follow the rules for upgrading memory as described below.

Restrictions

When adding memory, consider the following:

• Use only one type of SIMM in a given bank. You may combine different types of SIMMs for a memory configuration only if the SIMMs in each bank are the same type.

• You may use the memory banks (Bank0 ~ Bank3) in any order.

• Always install SIMMs in pairs. For example, for a total memory of

16 MB, install two 8 MB SIMMs in a bank. You cannot use a 16 MB SIMM alone for 16 MB of memory.

Expanding the PCI System

The system board has a PCI-to-PCI bridge controller chipset that expands the capability of the PCI system. This feature allows all five PCI slots in the system to be bus masters.

The bridge has two interfaces. The primary interface connects directly to the PCI bus close to the host CPU. The secondary interface creates a new PCI bus that can operate independently from the primary PCI bus.

3-12 Adding and Replacing Components

Installing PCI Devices

The devices you install in PCI slots 1 and 2 operate on the primary PCI bus. The devices you install in PCI slots 3, 4, and 5 operate on the secondary PCI bus.

Since the primary PCI bus operates faster than the secondary PCI bus, install PCI add-on boards in PCI slots 1 and 2 first. Then use PCI slots 3, 4, and 5. If you configure your PCI devices in this manner, the system will perform better. See Figure 2-7 in Chapter 2 of this manual for the locations of the PCI slots.

Installing PCI Devices

NCR S26 Hot Plug Server User Guide 3-13

Using the SCSI Feature

The system board features a single-chip Ultra Fast and Wide SCSI-2 host adapter that adds SCSI I/O capability to the system.

The chipset consists of all the components found on the state-of-the-art SCSI host adapters such as the following:

• Onboard microcontroller

• Bus master interface controller

• SCSI controller

The chipset allows transfers at a full 40 MB/second burst transfer rate. Note: Ultra SCSI speed is not supported on external SCSI devices because of

the Ultra SCSI stringent requirements in total SCSI bus length. To use an external SCSI devices, use the SCSISelect utility to disable support for Ultra SCSI speed. See the heading, “Configuring the SCSI Adapters and Drives” in the “Sample Standard Configuration” section of Appendix C.

To use the feature, install any SCSI device in your system and connect it to the SCSI interface on the system board. (See Figure 2-7 in Chapter 2 of this manual for the location.) Then, enter the BIOS Setup utility to set the PCI slot parameters. See Chapter 4, “Using the BIOS Setup Utility”, for details in setting the parameters. Refer to the SCSI manual for more information on using SCSI.

Using the BIOS Setup Utility

NCR S26 Hot Plug Server User Guide 4-1

When to Use the BIOS Setup Utility

Most systems are already configured by the manufacturer or the dealer. There is no need to run Setup when starting the computer unless you get a configuration error.

Running Setup loads the configuration values into the battery-backed nonvolatile memory called CMOS RAM. This memory area is not part of the system RAM.

Run Setup Message Repeatedly Received

If you repeatedly receive a Run Setup message, the battery may be bad. In this case, the system cannot retain the configuration values in CMOS. Ask a qualified technician for assistance.

Before Running Setup

Before you run Setup, do the following:

• Know the type of diskette drive you have. The standard type is a 3.5-inch

1.44 MB diskette drive.

• Close all files and applications.

4-2 Using the BIOS Setup Utility

Entering Setup

CAUTION: Close all open files and leave your application program before entering Setup. You cannot exit back into an application. The system automatically reboots when you leave Setup.

Note: The baud rate maximum value is only for the BIOS POST under UNIX environment. The system I/O chipset SMC 37C665GT supports up to

115.2 Kbps.

Enhanced IDE Features

This section describes several enhanced IDE features.

Hard Disk Block Mode

The Hard Disk Block Mode function enhances disk performance depending on the hard disk in use. If you set this parameter to Enabled, it permits data transfer in block (multiple sectors) by increasing the data transfer rate to 256 bytes per cycle.

If your system does not boot after enabling this parameter, change the setting to Disabled. This parameter is normally set to Disabled.

Hard Disk Size > 504 MB

This enhanced IDE feature works only under MS-DOS™ and Microsoft Windows™ 3.x environments. If enabled, it permits you to use a hard disk with a capacity of more than 504 MB. This is made possible through the Logical Block Address (LBA) mode translation. Other operating systems require this parameter to be set to Disabled.

Basic System Configuration

To prevent data loss, keep this parameter to Enabled if you are using a hard disk with more than 504 MB capacity and was previously configured through LBA mode. When you use a hard disk configured through the cylinder-headsector (CHS) mode, set this parameter to Disabled.

On Board IDE

This parameter permits the IDE to be disabled so that IRQ 14 can be used for PCI or EISA adapters.

NCR S26 Hot Plug Server User Guide 4-9

Basic System Configuration

Large Memory Support Mode

This parameter permits the system to support an extended memory higher than 64 MB. Set this parameter to Advanced if you are working under Microsoft Windows NT™ environment and the system memory size is greater than or equal to 64 MB. Otherwise, set it to Normal.

Num Lock After Boot

This parameter permits you to activate the Num Lock function upon booting. The default setting is Enabled.

Memory Test

When set to Enabled, this parameter permits the system to perform a RAM test during the POST routine. When set to Disabled, the system detects only the memory size and bypasses the test routine. The default setting is Disabled.

This item is set to Disabled and is not user-configurable if you enabled the Auto Configuration Mode and the Fast Boot Mode parameters on page 2 of the Basic System Configuration menu. See the following headings, “Auto Configuration Mode“ and “Fast Boot Mode.”

Auto Configuration Mode

When enabled, this parameter automatically sets the system configuration values to their optimized settings. At the same time, it causes the Memory Test parameter to be set to Disabled and the shadow RAM region for system and video BIOS to be set to Enabled. For additional information, see the headings, “Memory Test“ and “Shadow RAM.”

Set this parameter to Enabled if you do not know the hard disk drive type parameters and the onboard communication port configuration.

4-10 Using the BIOS Setup Utility

Fast Boot Mode

When enabled, this parameter permits the system to boot faster by skipping some POST routines. It bypasses memory test, enables shadow RAM, and enables primary- and second-level cache.

When set to Enabled, this parameter also causes the Memory Test parameter to be set to Disabled and the shadow RAM regions for system and video BIOS to Enabled. For additional information, see the headings, “Memory Test“ and “Shadow RAM.”

Shadow RAM

The system reserves 256 KB of random access memory (RAM) for the shadow RAM function. This parameter has eight range addresses. When you set these addresses to Enabled, the system BIOS, video BIOS, and I/O ROM functions run directly from the shadow RAM for faster operation. When you set them to Disabled, the functions run normally from ROM.

The address range E0000h - FFFFFh is for shadowing the system BIOS. This item is always set to Enabled and is not user-configurable. The address range C0000h - C7FFFh is for shadowing the video BIOS. Shadow RAM is set to Enabled and is not user-configurable if the Auto Configuration Mode and the Fast Boot Mode parameters on page 2 of the Basic System Configuration menu are enabled. Otherwise, you can disable this item.

The remaining address ranges are for I/O ROM functions.

Internal Cache (CPU Cache)

This parameter enables or disables the internal cache memory. It is set to Enabled and is not user-configurable if you enabled the Auto Configuration Mode and Fast Boot Mode parameters on page 2 of the Basic System Configuration menu. Otherwise, you can disable this item.

Advanced System Configuration

External Cache

This parameter enables or disables the external cache memory. It is set to Enabled and is not user-configurable if you enabled the Auto Configuration Mode and Fast Boot Mode parameters on page 2 of the Basic System Configuration menu. Otherwise, you can disable this item.

ECC/Parity Mode Selection

This parameter permits you to enable or disable the ECC and parity check feature. Fast-page mode SIMMs supports both ECC and parity mode while EDO SIMMs supports only ECC mode.

NCR S26 Hot Plug Server User Guide 4-13

Advanced System Configuration

You must disable this parameter if you installed SIMMs without parity.

Operation of ECC

This parameter permits you to select the error detection mode. The ECC operation options follow:

• None - detects single-bit errors and automatically corrects any error but does not set the single-bit error flag in the chipset. In this option, the operating system does not receive any signal even if there are system errors.

• Single-bit - detects single-bit errors, automatically corrects any error, and sets the single-bit error flag in the chipset. The setting of the single-bit error flag is a signal to the operating system that ECC detected single-bit errors.

• Multiple-bit - detects multiple-bit errors and sets the multiple-bit error flag in the chipset but does not correct the errors. The setting of the multiple-bit error flag is a signal to the operating system that ECC detected multiple-bit errors.

• Both - detects both single- and multiple-bit errors but corrects only single- bit errors. This option sets both the single-and multiple-bit flags in the chipset to send signals to the operating system that ECC detected errors.

Memory at 15 MB - 16 MB

To prevent memory address conflicts between the system and expansion boards, reserve this memory range for the use of either the system or an expansion board. Before setting this parameter, check your add-on expansion board manual to determine if the board needs this memory space. If not, set this parameter to System Use.

Expansion ROM Region

These items specify the memory regions available for add-on board use. You can manually assign specific regions to non-PnP boards so that the system will not use those regions when it automatically configures PnP boards.

NCR S26 Hot Plug Server User Guide 4-19

Non-PnP ISA Card Configuration

I/O Region

The items under this parameter permit you to reserve 16-byte memory address ranges for non-PnP boards. When the system configures PnP boards, the address ranges that you marked will not be used.

You can assign random memory addresses to non-PnP boards as long as you cover the address range required by the board. For example, for a board that requires 178h-188h address, you have to set regions 170h-17Fh and 180h18Fh to Yes.

Power Saving Configuration

IDE Hard Disk Standby Timer

This parameter permits the hard disk to enter standby mode after inactivity of 1 to 15 minutes, depending on your setting. When you access the hard disk again, allow 3 to 5 seconds (depending on the hard disk used) for the disk to return to normal speed. Set this parameter to Off if your hard disk does not support this function.

System Suspend Timer

This parameter supports the lowest power saving mode. To resume system operation from suspend mode, you can either press a key or move the mouse. Any IRQ activity representing green/wake up events also resumes system operation. See the following heading, “System Wake Up Events.”

Note: If you connected the system to a network, we strongly suggest you set this item to OFF.

System Wake Up Events

This parameter permits you to monitor system activities occurring through the IRQ and determine whether or not to enter power saving mode.

For example, if you assign IRQ3 to a fax/modem, and you set this item to Enabled, any fax/modem activity wakes up the system from suspend mode.
