Problem:

The Intel Server Board SDS2 system resource CD-ROMhas the following two

issues:

1. The BYO Platform Confidence Test Manual on the SDS2 system resource

CD-ROMis Rev. 2.0 dated 9/2001, rather than the latest Rev. 2.2 dated

10/2001. The instructions in the Rev. 2.0 manual for creating a bootable

Platform Confidence Test floppy diskette are not correct and do not contain

enough detail for the user to successfully create a bootable floppy diskette.

2. Editing a file with the DOS “Edit” command after booting to the SDS2

system resource CD-ROMwill cause the system to hang.

Implication:

A bootable Platform Confidence Test floppy diskette cannot be successfully

created by following the instructions in the SDS2 BYO Platform Confiedence

Test Manual Rev. 2.0 on the SDS2 system resource CD-ROM.Attempting to

edit a file with the DOS “Edit” command after booting to the SDS2 system

resource CD-ROMwill cause the system to hang.

Workaround:

Users should not use the DOS “Edit” command to edit files after booting to the

SDS2 System Resource CD-ROM.Users should also use the following

insturctions for the BYO Platform Confidence Test Manual Rev. 2.2 to create a

bootable Platform Confidence Test floppy diskette:

Installing the Server Board Platform Confidence Test Package on the Intel

Server Board SDS2:

1. Insert the resource CD into a Windows* based system and let the auto run

feature launch the graphical user interface (if auto run does not launch the

Problem:

Performance of the Intel® Server Board SDS2 memory subsystem is lower

than expected when CAS Latency 2 memory is used. The copy bandwidth

observed with CAS Latency 2 memory installed is less than the copy bandwidth

with CAS Latency 3 memory installed.

Implication:

The memory subsystem copy performance of the SDS2 Server Board is lower

with CAS Latency 2 memory installed than with CAS Latency 3 memory

installed.

Workaround:

Use of CAS Latency 3 memory is recommended for optimum memory

subsystem copy performance.

Status:

Fixed. This issue is fixed in SDS2 BIOS Production Release 2.4 (Build 47) and

later versions. When using SDS2 BIOS Production Release 2.4 (Build 47), the

copy bandwidth observed with CAS Latency 2 memory installed is greater than

the copy bandwidth with CAS Latency 3 memory installed.

Problem:

AC power cord.

Implication:

The described condition will appear if the SC5100 front panel cable is

disconnected from the SDS2 server board and then reconnected while 5V

standby voltage is applied to the system.

Workaround:

Disconnecting the AC power cord from the system will clear this condition.

Status:

NoFix. Disconnecting and reconnecting the SC5100 front panel cable from the

SDS2 server board while 5V standby voltage is applied to the system is not a

Fixed. This issue is fixed in SDS2 BIOS Production Release 2.5 (Build 48) and

later versions.

Problem:

In Table 73 of the Intel® Server Board SDS2 Technical Product Specification

(TPS) Rev. 1.0, the board level operating temperature is specified as 0°C to

55°C. In Table 75 of the SDS2 TPS Rev. 1.0, the power supply tolerance is

specified as ±5% for the 3.3V rail. Intel has induced a failure condition during

board level temperature and voltage margin testing at 55°C and±5% voltage on

the 3.3V rail in SDS2 Server Boards configured with PCI adapters in the

64bit/66MHz PCI slots under extreme workloads during final validation testing.

As a result, the SDS2 Server Board board level operating temperature

specification has been modified to 0°C to 45°C, and the power supply tolerance

specification for the 3.3V rail has been modified to ±3%. The SDS2 Server

Board passes board level temperature and voltage margin testing performed

according to these modified specifications.

Implication:

The SDS2 Server Board’s operating environment should be maintained within

the modified board level operating temperature specification of 0°C to 45°C and

the modified power supply tolerance specification of ±3% for the 3.3V rail. The

power supply tolerance specification for the 5V, 12V, and 5V standby rails is still

±5%. The system level operating temperature specification of the Intel® Server

Board SDS2 integrated into the Intel® SC5100 Server Chassis is still 0°C to

35°C. The Intel SC5100 Server Chassis’ cooling system is capable of

maintaining a SDS2 board level temperature below 45°C at a 35°C system

ambient temperature.

Workaround:

None.

Status:

Fix. Intel has identified a fix for this issue, which will be incorporated in the

SDS2 FAB 5 server board.

Problem:

A rubber bumper is included with the Intel® Server Board SDS2. Intel

On board NIC are not displayed during post but do appear in Boot Device menu.

These controllers will also attempt to do a PXE boot if no other bootable devices

are found.

Implication:

Not all boot devices displayed during POST when diagnostic display is enabled.

Workaround:

None. This is by design. The system BIOS builds the on-boardnetwork

controller Option ROM with an option that always makes the OPROM “quiet”. It

therefore does not display any text messages and does not allowing the CTRL-

Problem:

Add in Adaptec 39160 Ultra 160 controller installed in slots 5 & 6 causes an

Expansion ROM error after last system POST. No other adapters are present.

Implication:

Error message: Expansion ROM not initialized - PCI Mass Storage controller in

slot 06. Bus: 02, Device: 09, Function: 01

Workaround:

Adaptec's single image Option ROM requires one 'master' controlling channel

that is set using the <Ctrl-A>SCSI Select utility. Each channel loads the Option

ROM, determines whether it is the 'master' channel, and if not it unloads

completely. If it is the 'master', it proceeds to scan all devices and list all

possible drives. Only one channel does this scanning, but ALL channels load

the Option ROM initially if the Option ROM is enabled on the slot.

The error is coming from the second channel on the Adaptec 39160, even

though the first channel has already completed the 'master' scan. The reason it

is only happening in Slots 5 and 6 and when the NIC Option ROMs are all

loaded is because that is when the available Option ROM space is at a

minimum. The NIC Option ROM's are small, but apparently they make enough

difference. The onboard 7899 Option ROM loads after Slots 1-4,but before

Slots 5 & 6.

The solution here is to enable channel B of the ASC39160 as the 'master'

channel. When this is done, channel A loads the Option ROM, sees that it is not

the 'master', and unloads. Then channel B loads the Option ROM, does the full

scan of all devices, and remains in memory. At this point no other channels are

found, so no other devices error. The key here is that the LAST available

Adaptec channel should be listed as the Master - unfortunately, this is opposite

from their default - they default to the first available channel.

Intel has induced blue screens under Microsoft* Windows* 2000 in SDS2

sytems configured with a 3COM* 3C980C-TXNIC with driver el98xn5.sys

v3.48.0.0, and greater than 4GB of system memory installed, under extreme

workloads during network validation testing. This issue is not seen when up to

4GB of system memory is installed in the SDS2 system.

Implication:

Blue screens may be encountered under Microsoft* Windows* 2000 when

using a 3COM* 3C980C-TXNIC in an SDS2 system with greater than 4GB of

system memory installed.

Workaround:

This issue results because the 3COM 3C980C-TXNIC does not physically

support dual address cycles (DAC), therefore, the NIC is not able to access

physical addresses above 4GB. Due to negative performance impact, Intel

does not recommend using a NIC adapter that does not support DAC or 64-bit

PCI on a system with greater than 4GB of system memory installed. Intel

recommends installing a maximum of 4GB of system memory in the SDS2

system when utilizing the 3COM* 3C980C-TXNIC.

This issue does not occur when 3COM driver el98xn5.sys v4.0.0.15, which is

The SDS2 server board is capable of supporting a maximum total of 21 amps

on the 5V rail to the six PCI slots on the server board.

Implication:

The SDS2 server board can support a maximum total of 21 amps on the 5V rail

to the six PCI slots on the server board. Integrators must consider this when

selecting PCI card configurations for use in the SDS2 server board.

Workaround:

Select PCI cards that utilize a combination of 3.3V and 5V voltage in order to

minimize the current utilized by the PCI cards on the 5V rail.

Status:

No Fix.

Problem:

On board NIC are not displayed during post but do appear in Boot Device menu.

These controllers will also attempt to do a PXE boot if no other bootable devices

are found.

Implication:

Not all boot devices displayed during POST when diagnostic display is enabled.

Workaround:

None. This is by design. The system BIOS builds the on-boardnetwork

controller Option ROM with an option that always makes the OPROM “quiet”. It
