3. Functional Architecture
This chapter provides a high-level description of the functionality distributed between the architectural blocks of the Intel
®
Server Board SE7505VB2.
3.1 Processor and Memory Subsystem
The Intel® chipset E7505 provides a 36-bit address, 64-bit data processor host bus interface, operating at 533 MHz in the AGTL+ signaling environment. The MCH component of the chipset provides an integrated memory controller, an 8-bit hub interface, and one 16-bit hub interfaces.
The hub interface provides the interface to two 64-bit/100-MHz PCI-X buses and one 64-bit/66­MHz PCI bus via the P64H2, and the interface to two 32-bit/33-MHz PCI buses via the ICH4. The board directly supports up to 8 GB of ECC memory, using four DDR266 compliant ECC DIMMs. The ECC implementation in the MCH can detect and correct single-bit errors (SBE), detect multiple-bit errors (MBE), and supports Intel SDDC) feature with x4 DIMMs.
3.1.1 Processor Support
The Intel Server Board SE7505VB2 supports one or two processors in the 604-pin FCPGA package. When two processors are installed, all processors must be of identical revision, core voltage, and bus/core speed. When only one processor is installed, it should be in the socket labeled CPU1 and the other socket must be empty. The support circuitry on the server board consists of the following:

Intel Xeon mPGA / FCPGA 2.0GHz 512KB 400 / 533
Intel Xeon mPGA / FCPGA 1.8GHz 512KB 400
Notes:
Processors must be populated in sequential order. Processor socket 1 must be
populated before processor socket 2.
The board is designed to provide up to 65A of current per processor. Processors with
higher current requirements are not supported.
No terminator is required in the second processor socket when using a uni-processor
configuration.

Intel part number C32194-002
Intel® Server Board SE7505VB2 Functional Architecture
In addition to the circuitry described above, the processor subsystem contains the following:
Reset configuration logic Processor module presence detection logic Server management registers and sensors
3.1.1.1 Processor VRD
The Intel Server Board SE7505VB2 has a single VRD (Voltage Regulator Down) to support two processors. It is compliant with the VRM 9.1 specification and provides a maximum of 130 AMPs, which is capable of supporting the requirements for two Intel
®
Xeon™ processors.
The board hardware and PMC (Power Management Controller) must read the processor VID (voltage identification) bits for each processor before turning on the VRD. If the VIDs of the two processors are not identical, then the PMC will not turn on the VRD.
3.1.1.2 Reset Configuration Logic
The BIOS determines the processor stepping, cache size, etc through the CPUID instruction. The requirements are as follows:
All processors in the system must operate at the same frequency, have the same cache
sizes, and same VID. No mixing of product families is supported.
Processors run at a fixed speed and cannot be programmed to operate at a lower or
higher speed.
The processor information is read at every system power-on.
Note: The processor speed is the processor power on reset default value. No manual processor speed setting options exist either in the form of a BIOS setup option or jumpers.
3.1.1.3 Processor Module Presence Detection
Logic is provided on the baseboard to detect the presence and identity of installed processors. The PMC checks the logic and will not turn on the system DC power unless the VIDs of both the processors match in a DP configuration.
3.1.1.4 Interrupts and APIC
Interrupt generation and notification to the processors is done by the APICs in the ICH4 and the P64H2 using messages on the front side bus.
3.1.2 Memory Subsystem
The baseboard supports up to four DIMM slots for a maximum memory capacity of 8 GB. The DIMM organization is x72, which includes eight ECC check bits. The memory interface runs at 266MT/s. The memory controller supports memory scrubbing, single-bit error correction and multiple-bit error detection and Intel x4 SDDC support with x4 DIMMs. Memory can be implemented with either single sided (one row) or double-sided (two row) DIMMs.

Figure 2. Memory Sub-system Block Diagram
3.1.2.1 Memory DIMM Support
The board supports DDR266-compliant ECC DIMMS operating at 266MT/s. Only DIMMs tested and qualified by Intel or a designated memory test vendor are supported on this board. A list of qualified DIMMs is available at http://support.intel.com/support/motherboards/server/se7505vb2 Note that all DIMMs are supported by design, but only fully qualified DIMMs will be supported on the board.
The minimum supported DIMM size is 128 MB. Therefore, the minimum main memory configuration is 1 x 128 MB or 128 MB. The largest size DIMM supported is a 2 GB registered DDR266 ECC DIMM based on 512 megabit technology. Therefore the maximum main memory configuration is 4 x 2 GB or 8 GB.
Only registered DDR266 compliant, ECC, DDR memory DIMMs will be supported ECC single-bit errors (SBE) will be corrected and multiple-bit error (MBE) will be
detected.
Intel server board also supports Intel x4 SDDC with x4 DIMMs. The maximum memory capacity is 8 GB The minimum memory capacity is 128 MB

There are two banks of DIMMs, labeled 1 and 2. Bank 1 contains DIMM socket locations 1A and 1B. Bank 2 contains 2A and 2B. The sockets associated with each bank are located next to each other and the DIMM socket identifiers are marked on the baseboard silkscreen, near the DIMM socket.
For designs that require a lower price point, a single 128 MB DIMM can be populated in the DIMM1A socket. When a single DIMM is installed, interleaving and Intel x4 SDDC are not available. Bank 2 will only operate with two DIMMs installed.
The baseboard’s signal integrity and cooling are optimized when memory banks are populated in order. Before populating either DIMM socket in bank 2, both DIMMs in bank 1 must be populated. No empty DIMM sockets are allowed between populated DIMMs.
DIMM and memory configurations must adhere to the following:
DDR266 ECC, registered, DDR DIMM modules DIMM organization: x72 ECC Pin count: 184 DIMM capacity: 128 MB, 256 MB, 512 MB, 1 GB, 2GB DIMMs Serial PD: JEDEC Rev 2.0 Voltage options: 3.3 V (VDD/VDDQ) Interface: SSTL2
3.1.2.3 Memory Cooling
The SE7505VB2 server board supports DDR memory in a variety of sizes and densities (see Table 4). Due to the specific orientation of the memory on the SE7505VB2 server board, certain memory densities and configurations are more difficult to cool in chassis that provide traditional front to back airflow such as the Intel SC5200 and SC5250-E server chassis. To ensure the memory used with this board has sufficient thermal margin to operate within specifications, Intel has designed a memory cooling duct specifically for the SE7505VB2 server board. Intel’s testing has shown only 2GB and stacked 1GB (low profile) DIMMs are thermally at risk. If your specific design uses either of these size memory parts, contact Intel Customer Support and request the SE7505VB2 server board memory cooling duct, part number C28482-
001.

3.1.2.5 DRAM ECC
The ECC used for DRAM provides Intel x4 SDDC technology for x4 SDRAMs. DRAMs that are x8 use the same algorithm but will not have Intel x4 SDDC technology, since at most only four bits can be corrected with this ECC.
The method provides more ECC bits so each ECC word can correct more than a single-bit failure. This is possible because different mathematical algorithms provide multiple-bit correction with the right number of data bits and ECC bits. For example, a 144-bit ECC word that consists of 128 data bits and 16 ECC bits can be used to correct up to 4 bit errors within certain bit fields of data. These four bits must be adjacent, not random. Even though the ratio of the ECC bits to data bits is the same as the previous example (16/128 vs. 8/64), the longer ECC word allows for a correction and detection algorithm that is more efficient.
3.2 The Intel® E7505 Chipset
The Intel Server Board SE7505VB2 is designed around the Intel E7505 chipset. The chipset provides an integrated I/O bridge and memory controller, and a flexible I/O subsystem core (PCI / PCI-X) . This is targeted for multiprocessor systems and standard high-volume servers. The chipset consists of three components:
MCH: Memory Control Hub. The MCH accepts access requests from the host
(processor) bus and directs those accesses to memory or to one of the PCI buses. The MCH monitors the host bus, examining addresses for each request. Accesses may be directed to a memory request queue for subsequent forwarding to the memory subsystem, or to an outbound request queue for subsequent forwarding to one of the PCI buses. The MCH also accepts inbound requests from the P64H2 and the ICH4. The MCH is responsible for generating the appropriate controls to control data transfer to and from memory.
P64H2: PCI-X 64bit Hub 2.0 I/O Bridge. The P64H2 provides the interface for two PCI-
X buses capable of 133MHz operation. The P64H2 is both master and target on both buses.
Revision 1.2 Intel part number C32194-002
21
Functional Architecture Intel® Server Board SE7505VB2
ICH4: I/O Controller Hub 4. The ICH4 controller has several components. It provides
the interface for a 32-bit/33-MHz PCI bus. The ICH4 can be both a master and a target on that PCI bus. The ICH4 also includes a USB 2.0 controller and an IDE controller. The ICH4 is also responsible for much of the power management functions, with ACPI control registers built in. The ICH4 also provides a number of GPIO pins and has the LPC bus to support low speed legacy I/O.
The MCH, P64H2, and ICH4 chips provide the pathway between processor and I/O systems. The MCH is responsible for accepting access requests from the host (processor) bus, and directing all I/O accesses to one of the PCI buses or legacy I/O locations. If the cycle is directed to one of the 64-bit PCI segments, the MCH communicates with the P64H2 through a private interface called the HI (Hub Interface). If the cycle is directed to the ICH4, the cycle is output on the MCH’s 8-bit HI 1.5 bus. The P64H2 translates the HI 2.0 bus operation to a 64-bit PCI signaling environment operating between 133 MHz and 33 MHz.
The HI 2.0 bus is 16 bits wide and operates at 66 MHz with 512MT/s, providing over 1 GB per second of bandwidth.
All I/O for the board, including PCI and PC-compatible I/O, is directed through the MCH and then through either the P64H2 or the ICH4 provided PCI buses.
The ICH4 provides one 32-bit/33-MHz PCI bus hereafter called P32-A. The P64H2 provides one 64-bit/100-MHz PCI-X bus, hereafter called P64-B, and one
64bit/66MHz PCI bus, hereafter called P64-C.
This independent bus structure allows all three PCI buses to operate independently and concurrently providing additional bandwidth to the system.
3.2.1 MCH Memory Architecture Overview
The MCH supports a 144-bit wide memory sub-system that can support a maximum of 8 GB of DDR266 memory using 2 GB DIMMs. This configuration needs external registers for buffering the memory address and control signals. The four chip selects are registered inside the MCH and need no external registers for chip selects.
The memory interface runs at 266MT/s. The memory interface supports a 72-bit or 144-bit wide memory array. It uses fifteen address lines (BA [1:0] and MA [12:0]) and supports 64 Mb, 128 Mb, 256 Mb, 512 Mb DRAM densities. The DDR DIMM interface supports memory scrubbing, single-bit error correction, and multiple bit error detection and Intel x4 SDDC with x4 DIMMs.

3.2.2 Memory Controller Hub (MCH)
The MCH is a 1005-ball FC-BGA device and uses the proven components of previous generations like the Intel Xeon processor bus interface unit, the hub interface unit, and the DDR memory interface unit. In addition, the MCH incorporates a hub interface (HI) . The HI interface allows the MCH to directly interface with the P64H2. The MCH also increases the main memory interface bandwidth and maximum memory configuration with a 144-bit wide memory interface.
The MCH integrates the following main functions:
An integrated high performance main memory subsystem. An HI 2.0 bus which provides an interface to the P64H2 An HI 1.5 bus which provides an interface to the ICH4 AGP pro slot: Video controller with 3D/2D graphics accelerator
Other features provided by the MCH include the following:
Full support of ECC on the processor bus Full support of Intel x4 SDDC on the memory interface with x4 DIMMs Twelve deep in-order queue, two deep defer queue Full support of registered DDR266 ECC DIMMs. Support for 2 GB DDR memory modules Memory scrubbing

5. PCI I/O Subsystem
5.1 PCI Subsystem
The primary I/O bus for the server board SE7505VB2 is PCI, with three independent PCI bus segments. The PCI buses comply with the PCI Local Bus Specification, Rev 2.3. The P32-A bus segment is directed through the ICH4 while the two 64-bit segments, P64-B and P64-C, are directed through the P64H2 I/O Bridge. The table below lists the characteristics of the three PCI bus segments.
Table 7. PCI Bus Segment Characteristics
PCI Bus Segment Voltage Width Speed Type PCI I/O Card Slots
P32-A 5 V 32-bits 33 MHz PCI Two slots, support full-length cards
P64-B 3.3 V 64-bits 100 MHz PCI-X Two slots, support full-length cards
P64-C 3.3 V 64-bits 66 MHz PCI One slot, supports full-length cards
5.1.1 P32-A: 32-bit/33-MHz PCI Subsystem
All 32-bit/33-MHz PCI I/O for the board is directed through the ICH4. The 32-bit/33-MHz PCI segment created by the ICH4 is known as the P32-A segment. The P32-A segment supports the following embedded devices and connectors:
Serial ATA controller: Silicon Image* 3112A. One 10/100 Network Interface Controller: Intel 82550PM Fast Ethernet Controller. 2D/3D Graphics Accelerator: ATI Rage XL Video Controller
The Serial ATA controller and the NIC will each be allocated a GPIO to disable the device. The video controller will be disabled when an off-board video device is detected in either the AGP or PCI bus segments
5.1.1.1 Device IDs (IDSEL)
Each device under the PCI hub bridge has its IDSEL signal connected to one bit of AD[31:16], which acts as a chip select on the PCI bus segment in configuration cycles. This determines a unique PCI device ID value for use in configuration cycles. The following table shows the bit to which each IDSEL signal is attached for P32-A devices and the corresponding device description.

5.1.1.2 P32-A Arbitration
P32-A supports six PCI devices: the ICH4 and five PCI bus masters (one NIC, one sATA RAID controller, two PCI slots and one ATI Rage XL video controller). All PCI masters must arbitrate for PCI access, using resources supplied by the ICH4. The host bridge PCI interface (ICH4) arbitration lines REQx* and GNTx* are a special case in that they are internal to the host bridge. The following table defines the arbitration connections.

5.1.2 P64-B and P64-C: 64-bit/100- or 66-MHz PCI Subsystem
Two peer 64-bit bus segments are directed through the P64H2 I/O Bridge. The first PCI segment, P64-B, provides two 3.3V 64-bit PCI-X slots capable of 100 MHz operation and support full-length PCI cards.
The second PCI segment, P64-C, provides a single 3.3V 64-bit PCI slot operating at 66 MHz. This segment supports full-length PCI cards. P64-C also has an embedded Intel 82540EM fast Ethernet gigabit controller.
5.1.2.1 Device IDs (IDSEL)
Each device under the PCI hub bridge has its IDSEL signal connected to one bit of AD[31:16], which acts as a chip select on the PCI bus segment in configuration cycles.

5.2 Serial ATA Controller
The board provides an embedded dual port Serial ATA controller through the use of the Silicon Image* 3112A ASIC. The Silicon Image 3112A provides a single 32-bit / 33-MHz PCI bus master interface as a multifunction device, packaged in a 128-pin PQFP. It supports two modes: base mode and RAID mode.
The Silicon Image 3112A controller supports the following features:
Automatically selects highest available transfer speed for all devices Supports:
- UDMA up to 150MB/second
- All UDMA and PIO modes
- Up to two SATA devices
- ACPI and ATA/ATAPI6

PCI I/O Subsystem Intel® Server Board SE7505VB2
The baseboard ships with the Silicon Image controller set to Base ATA mode. To switch the controller to RAID mode, a utility needs to be downloaded from the SE7505VB2 support website or run from the resource CD. This utility switches the controller from one mode to the other. Appropriate drivers need to be loaded, depending on the mode the controller is set to.
This method was chosen over a BIOS F2 setup switch to allow the controller settings to be maintained in the event of a Clear CMOS operation. If the RAID drivers were loaded and a Clear CMOS operation was executed, but the device was not reset to RAID mode, the operating system would not load. Refer to the SE7505VB2 support website for details on which operating systems support RAID mode.
Note: The onboard NICs need to be enabled for the ATA mode/RAID mode utility to properly program the device. The utility toggles the Sub-System ID (SSID) in the NIC EEPROM between two different values. The BIOS will load the appropriate Silicon Image Option ROM based on the SSID that is set in the NIC EEPROM. The NICs need to be enabled for the BIOS to know which SSID is set and subsequently which option ROM to load.
When in RAID mode, the Silicon Image controller can support the following RAID levels:
Table 14. sATA RAID Level
RAID Level Performance Capacity # of
Drives
RAID 0 (Striping) Highest Number of drives multiplied
by the smallest drive size
RAID 1 (Mirroring)
Normal 50% min 2
2
RAID 0 configurations are primarily used for high performance applications, as it doubles the sustained transfer rate of its drives. RAID 1 configurations are primarily used for data protection. RAID 1 creates an identical backup of the primary drive to a secondary drive. Whenever a disk write is performed, the controller sends data simultaneously to a second drive located on a different data channel.
5.3 Video Controller
The baseboard provides an ATI Rage XL PCI graphics accelerator, along with 8 MB of video SDRAM and support circuitry for an embedded SVGA video subsystem. The ATI Rage XL chip contains a SVGA video controller, clock generator, 2D and 3D engine, and RAMDAC in a 272­pin PBGA. One 2Mx32 SDRAM chip provides 8 MB of video memory.
The SVGA subsystem supports a variety of modes, up to 1600 x 1200 resolution in 8/16/24/32 bpp modes under 2D, and up to 1024 x 768 resolution in 8/16/24/32 bpp modes under 3D. It supports both CRT and LCD monitors with up to 100 Hz vertical refresh rate.
The baseboard provides a standard 15-pin VGA connector at the rear of the system, in the standard ATX I/O opening area. The video controller disabled by default in BIOS Setup when an off-board video adapter is detected in either the AGP or PCI slots. Optionally, the video controller can be set to support dual monitor mode when an off-board AGP adapter is detected. The onboard controller would act as the primary video controller and the AGP adapter becomes the secondary adapter under an operating system that supports this functionality.

PCI I/O Subsystem Intel® Server Board SE7505VB2
5.5 Interrupt Routing
The board interrupt architecture accommodates both PC-compatible PIC mode and APIC mode interrupts through use of the integrated I/O APICs in the ICH4.
5.5.1 Legacy Interrupt Routing
For PC-compatible mode, the ICH4 provides two 82C59-compatible interrupt controllers. The two controllers are cascaded with interrupt levels 8-15 entering on level 2 of the primary interrupt controller (standard PC configuration). A single interrupt signal is presented to the processors, to which only one processor will respond for servicing. The ICH4 contains configuration registers that define which interrupt source logically maps to I/O APIC INTx pins.
The ICH4 handles both PCI and IRQ interrupts. The ICH4 translates these to the APIC bus. The numbers in the table below indicate the ICH4 PCI interrupt input pin to which the associated device interrupt (INTA, INTB, INTC, INTD) is connected. The ICH4 I/O APIC exists on the I/O APIC bus with the processors.

P32-A Slot 1 ICH4_PIRQF# ICH4_PIRQG# ICH4_PIRQH# ICH4_PIRQE#
5.5.2 APIC Interrupt Routing
For APIC mode, the baseboard interrupt architecture incorporates three Intel® I/O APIC devices to manage and broadcast interrupts to local APICs in each processor. The Intel I/O APICs monitor each interrupt on each PCI device, including PCI slots in addition to the ISA compatibility interrupts IRQ(0-15).
When an interrupt occurs, a message corresponding to the interrupt is sent across a three-wire serial interface to the local APICs. The APIC bus minimizes interrupt latency time for compatibility interrupt sources. The I/O APICs can also supply greater than 16 interrupt levels to the processor(s). This APIC bus consists of an APIC clock and two bidirectional data lines.

5.5.3 Serialized IRQ Support
The SE7505VB2 server board supports a serialized interrupt delivery mechanism. Serialized Interrupt Requests (SERIRQ) consists of a start frame, a minimum of 17 IRQ / data channels, and a stop frame. Any slave device in the quiet mode may initiate the start frame. While in the continuous mode, the start frame is initiated by the host controller.
5.5.4 IRQ Scan for PCIIRQ
The IRQ / data frame structure includes the ability to handle up to 32 sampling channels with the standard implementation using the minimum 17 sampling channels. The board has an external PCI interrupt serializer for PCIIRQ scan mechanism of ICH4 to support 16 PCIIRQs.
5.6 PCI Error Handling
The PCI bus defines two error pins, PERR# and SERR#, for reporting PCI parity errors and system errors, respectively. In the case of PERR#, the PCI bus master has the option to retry the offending transaction, or to report it using SERR#. All other PCI-related errors are reported by SERR#. SERR# is routed to NMI if enabled by BIOS.

SE7505VB2 ACPI Implementation Intel® Server Board SE7505VB2
7. SE7505VB2 ACPI Implementation
7.1 ACPI
An ACPI-aware operating system generates an SMI to request that the system be switched into ACPI mode. The BIOS responds to enable ACPI mode. The system automatically returns to legacy mode upon hard reset or power-on reset.
The SE7505VB2 platform supports S0, S1, S4, and S5 states. When the system is operating in ACPI mode, the OS retains control of the system and OS policy determines the entry methods and wake up sources for each sleep state
Note: Sleep entry and wake up event capabilities are provided by the hardware but are enabled by the operating system.
S0 Sleep State
S1 Sleep State
S4 Sleep State
S5 Sleep State
The S0 sleep state is when everything is on. This is the state that no sleep is enabled.
The S1 sleep state is a low wake-up latency sleep state. In this state, no system context is lost (Processor or chipset). The system context is maintained by the hardware.
The S4 Non-Volatile Sleep state (NVS) is a special global system state that allows system context to be saved and restored (relatively slowly) when power is lost to the baseboard. If the system has been commanded to enter the S4 sleep state, the operating system will write the system context to a non-volatile storage file and leave appropriate context markers.
The S5 sleep state is similar to the S4 sleep state except the operating system does not save any context nor enable any devices to wake the system. The system is in the “soft” off state and requires a complete boot when awakened.
7.1.1 Front Panel Switches
The baseboard supports two front panel buttons:

Intel part number C32194-002
Intel® Server Board SE7505VB2 SE7505VB2 ACPI Implementation
The power button input (SW2#) provides PWRBTN_IN signal to the sIO. The power button input behaves differently depending on whether or not the operating system supports ACPI.
Power Button Off to On:
The sIO may be configured to generate wakeup events for several different system events: Wake on LAN*, PCI Power Management Interrupt, and Real Time Clock Alarm are examples of these events. Since the processors are not executing, the BIOS does not participate in this sequence. The sIO provides ONSTL# signal to the power supply. The ICH4 and receive power good and reset and then transition to an ON state.
Power Button On to Off (Legacy):
The ICH4 is configured to generate an SMI due to a power button event. The BIOS services this SMI and sets the state of the machine in the ICH4 and sIO to the OFF state.
Power Button On to Off (ACPI):
If an ACPI operating system is loaded, the power button switch generates a request (via SCI) to the OS to shutdown the system. The OS retains control of the system and determines what sleep state (if any) the system transitions to.
Reset Button:
NMI Button:
The reset button will generate a hard reset to the system.
The NMI button will force an NMI to the processors.
7.1.2 Wake up Sources (ACPI and Legacy)
The baseboard is capable of wake up from several sources under a non-ACPI configuration, such as when the operating system does not support ACPI. The wake up sources are defined in the following table.
Table 19. Supported Wake Events
Wake Event Supported via ACPI
(by sleep state)
Power Button Always wakes system Always wakes system
Ring indicate from serial1 S1, S4, S5 S5
Ring indicate from serial2 S1, S4, S5 S5
PME from PCI 32/33 S1, S4, S5 S5
PME from PCI secondary 64/100 S1, S4, S5 S5
PME from primary PCI 64/66 S1, S4, S5 S5
RTC Alarm S1, S4 No
Mouse S1 No
Keyboard S1 No
USB S1 No
Supported Via Legacy Wake
Under ACPI, the operating system programs the ICH4 and sIO to wake up on the desired event, but in legacy mode, the BIOS enables/disables wake up sources based on an option in BIOS Setup. The operating system or a driver must clear any pending wake up status bits in the associated hardware (such as the Wake on LAN status bit in the LAN application specific integrated circuit (ASIC), or PCI Power Management Event (PME) status bit in a PCI device. The legacy wake up feature is disabled by default.

1. These are “Reserved ” pins on the Intel the system designer must terminate these signals to the processor VCC.
2. Baseboards treating AA3 and AB3 as Reserved will operate correctly with a bus clock of 100 MHz.
3. The FC-mPGA2P package contains an extra pin (located at location AE30) compared to the INT-mPGA package. This additional pin serves as a keying mechanism to prevent the FC-mPGA2P package from being installed in the 603-pin socket. Since the additional contact for pin AE30 is electrically inert, the 604-pin socket will not have a solder ball at this location.

9. Configuration Jumpers
This section describes configuration jumper options on the Intel Server Board SE7505VB2.
9.1 System Recovery and Update Jumpers
A 10-pin block (J4J1), located just below the DIMM connectors, provides a total of four 2-pin jumper blocks that are used to configure several system recovery and update options. The figure below shows the jumper pins and their functions. The factory defaults are set to a protected mode for each function.
Two jumpers are stored on four pins during normal operation. The BIOS bootblock write protect jumper on pins 7-8 should be left on these pins at all times except when instructed by the BIOS release notes to remove it. The jumper stored on pins 9-10 is used to perform different functions depending on the pins it is placed. For normal operation, this jumper should be on the storage pins.

10. BIOS
10.1 Using the BIOS Setup Utility
This section describes the BIOS Setup Utility options. For more details on the BIOS and its functionality, contact your Intel field representative to obtain the Intel Server Board SE7505VB2 BIOS External Product Specification (Note that access to this document is restricted). Use BIOS Setup to change the server configuration defaults. You can run BIOS Setup with or without an operating system being present.
10.1.1 If You Cannot Access Setup
If you are not able to access BIOS Setup, you might need to clear the CMOS memory.
10.1.2 Starting Setup
You can enter and start BIOS Setup under several conditions:
When you turn on the server, after POST completes the memory test When you have moved the CMOS jumper on the server board to the “Clear CMOS”
position (enabled)
In the two conditions listed above, after rebooting, you will see this prompt:
Press <F2> to enter SETUP
In a third condition, when CMOS/NVRAM has been corrupted, you will see other prompts but not the <F2> prompt:
Warning: CMOS checksum invalid Warning: CMOS time and date not set
When this happens, the BIOS will load default values for CMOS and attempt to boot.
10.1.3 Setup Menus
Each BIOS Setup menu page contains a number of features. Except for those that are provided for informational purposes, each feature is associated with a value field that contains user­selectable parameters. Parameters may be changed depending upon the security option chosen. If a value is not changeable due to insufficient security privileges (or other reasons), the feature’s value field becomes inaccessible.
The bottom portion of the BIOS Setup screen provides a list of commands that are used for navigating the Setup utility. Table 46 describes the keyboard commands you can use in the BIOS Setup menus.

Before you upgrade the BIOS, prepare for the upgrade by recording the current BIOS settings, obtaining the upgrade utility, reviewing the release notes, and making a copy of the current BIOS.
10.2.1.1 Recording the Current BIOS Settings
1. Boot the computer and press <F2> when you see the message:
Press <F2> Key if you want to run SETUP
2. Write down the current settings in the BIOS Setup program or go to the Exit menu and choose to “Save Custom Defaults”.
Note: Do not skip step 2. You will need these settings to configure your computer at the end of the procedure.
If you chose to “Save Custom Defaults,” after the new BIOS is flashed, you can restore your settings from the “Load Custom Default” option.
10.2.1.2
Obtaining the Upgrade Utility
You can upgrade to a new version of the BIOS using the new BIOS files and the BIOS upgrade utility, PHLASH16.EXE. You can obtain the BIOS upgrade file and the PHLASH.EXE utility from the Intel Customer Support Web site:
http://support.intel.com/support/motherboards/server/SE7505VB2
Note: Please review the instructions distributed with the upgrade utility before attempting a BIOS upgrade. Review also any release notes that accompany the new version of the BIOS. The release notes may contain critical information regarding jumper settings, specific fixes, or other information to complete the upgrade.
Note: The PHLASH16.EXE program will not work in a HIMEM controlled DOS environment by default. You’ll need to add the ‘/X’ switch after the PHLASH16.EXE command to enable your BIOS Update to work if HIMEM is loaded.
This upgrade utility allows you to upgrade the BIOS in flash memory. The following steps explain how to upgrade the BIOS.

10.2.1.3 Creating a Bootable Diskette
1. Use a DOS system to create the diskette.
2. Insert a diskette in diskette drive A.
3. At the C:\ prompt, for an unformatted diskette, type:
format a:/s
or, for a diskette that has already been formatted, type:
sys a:
4. Press <Enter>.
10.2.1.4 Creating the BIOS Upgrade Diskette
The BIOS upgrade file is a compressed self-extracting archive that contains the files you need to upgrade the BIOS.
1. Download the BIOS image file to a temporary folder on your hard drive. The image is available from http://support.intel.com/support/motherboards/server/SE7505VB2
2. Execute the BIOS.EXE file to extract the update files from the image file.
3. Insert the bootable diskette you created in the steps above into the diskette drive.
4. Copy the BIOS update files from the temporary folder onto the bootable diskette.
10.2.2 Upgrading the BIOS
Note: Make sure to read your BIOS release notes for any specific instructions on updating
the BIOS (i.e. special jumper settings).
1. Place the bootable diskette containing the BIOS update files into the diskette drive of your system. Boot the system with the diskette in the drive.
2. A menu will appear with two options. Use option 1 to automatically update the system BIOS (See step 3). Use option 2 to manually update the system BIOS and the User Binary (See step 4).
3. If you selected option 1, to automatically update the system BIOS: The system will execute the Phlash update utility and update the BIOS. When the update is complete, the utility will display a green box with a message that says “Completed Successfully.” The system will then reboot. Skip to step 5.

4. If you selected option 2, to manually update the BIOS or to update the flash memory, you can either select “Update Flash Memory From a File” or “Update System BIOS”:
Update Flash Memory From a File: When prompted for a file name, type BIOS.wph
and press Enter.
Update System BIOS: The system will warn you that the BIOS will be updated.
Verify the BIOS version is correct and press Enter to continue. When the update is complete, the utility will display a green box with a message that says “Completed Successfully.” The system will then reboot.
5. Wait while the BIOS files are updated. Do not power down the system during the BIOS update process! The system should reset automatically when the BIOS update process is completed. If it does not and the green box is displayed, go ahead and reboot the machine manually. Remove the diskette from the diskette drive.
6. Check to make sure the BIOS version displayed during POST is the new version as the system reboots.
7. Enter Setup by pressing the F2 key during boot. Once in Setup, press the F9 and <Enter> to set the parameters back to default values. If you do not set the CMOS values back to defaults using the F9 key, the system may function erratically.
8. Re-enter the values you wrote down at the beginning of this process, or if you saved your Custom Defaults, reload them by choosing from the Exit menu, the Load Custom Defaults option. Press F10 and <Enter> to exit BIOS Setup and Save Changes.
Note: You may encounter a CMOS Checksum error or other problem after reboot. Try shutting down the system and booting up again. CMOS checksum errors require that you enter Setup, check your settings, save your settings, and exit Setup.
10.2.3 Crisis Recovery Diskette
It is unlikely that anything will damage the BIOS; however, a recovery disk should be created to ensure a quick recovery should it happen. The following steps explain how to create the crisis recovery diskette.
You can obtain the Crisdisk.exe file needed to create the crisis disk from the Intel Customer Support Web site: http://support.intel.com/support/motherboards/server/SE7505VB2

10.2.3.1 Creating the Crisis Recovery Diskette
Note: The crisis recovery diskette must be created on a Windows 98, Windows 2000, or
Windows XP system.
Use the following steps to create the diskette:
1. Create an empty folder at the Windows workstation.
2. Copy the Crisdisk.exe folder into the folder and execute the command Crisdisk to extract the contents of the self-extracting file into the folder.
3. Insert an empty diskette into the A: drive.
4. While in the folder with the Crisdisk contents, type Wincris.
5. You will be prompted by a screen that contains three options:
Create MINIDOS Crisis Disk: Installs the necessary recovery files onto the A: drive.
Use this option if the diskette you are using is already formatted and bootable.
Create FULLDOS Crisis Disk: Makes the floppy disk in A: bootable and then installs
the necessary recovery files. Use this option if the diskette you are using is blank, but not bootable.
Format the A: Drive Diskette: Formats the diskette in the A: drive. Use this option if
the diskette is not blank. When this option is complete, you will then need to use the “Create FULLDOS Crisis Disk option.”
When the crisis diskette has been created, you will be prompted with a message to remove the diskette. You will then be asked whether you want to create additional crisis diskettes.
