Intel Corporation server baseboards contain a number of high-density VLSI and power delivery
components which need adequate airflow to cool. Intel’s own chassis are designed and tested to meet
the intended thermal requirements of these components when the fully integrated system is used
together. It is the responsibility of the system integrator that chooses not to use Intel developed server
building blocks to consult vendor datasheets and operating parameters to determine the amount of
airflow required for their specific application and environmental conditions. Intel Corporation cannot be
held responsible if components fail or the server board does not operate correctly when used outside any
of its published operating or non-operating limits.
The Intel® Server Board SE7221BK1-E may contain design defects or errors known as errata which may
cause the product to deviate from published specifications. Current characterized errata are available on
request.

SE7221BK1-E Technical Product Specification
3. Functional Architecture
This chapter provides a high-level description of the functionality distributed between the
architectural blocks of the Intel® Server Board SE7221BK1-E.
3.1 Processor Subsystem
The Intel® Server Board SE7221BK1-E supports Intel® Pentium® 4 and Celeron® D
processors in the 775-land package, which is a follow on to Pentium® 4 and Celeron® D
processors in the 478-pin package, with enhancements to the Intel® NetBurst® micro-
architecture. Intel® Pentium® 4 and Celeron® D processors built on 90nm process technology
in the 775-land package utilize Flip-Chip Land Grid Array (FC-LGA4) package technology, and
plug into a 775-land LGA socket, referred to as the LGA775 socket. Pentium® 4 and Celeron®
D processors in the 775-land package, like their predecessors in the 478-pin package, are
based on the same Intel® 32-bit micro-architecture and maintain the tradition of compatibility
with IA-32 software. Specific models of the Pentium® 4 Processor in the LGA775 package
support Intel® EM64T (Extended Memory 64 Technology) for 64bit native mode operation with
64bit operating systems. The Intel® Celeron® Processor currently does not support EM64T.
3.1.1
Processor VRD
The Intel® Server Board SE7221BK1-E has a VRD (Voltage Regulator Down) to support one
processor. It is compliant with the VRM 10.1 DC-DC Converter Design Guide Line and provides
a maximum of 120A, which is capable of supporting the requirements for Intel® Pentium® 4 and
Intel® Celeron® D processors.
The board hardware must monitor the processor VTTEN (Output enable for VTT) pin before
turning on the VRD. If the VTTEN pin of the processors is not identical the Power ON Logic will
not turn on the VRD.
3.1.2
Reset Configuration Logic
The BIOS determines the processor stepping, cache size, etc through the CPUID instruction.
The requirements are as follows:
ƒ
Processors run at a fixed speed, but can be programmed by BIOS to operate at a lower
or higher speed.

3.2 Memory Subsystem
The baseboard supports up to four DIMM slots for a maximum memory capacity of 4 GB. The
DIMM organization is x72, which includes eight ECC check bits. The memory interface runs at
400/533MT/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.
3.2.1.1
Memory DIMM Support
The board supports un-buffered (not registered) DDR2 400/533-compliant ECC or Non-ECC
DIMMs operating at 400/533MT/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/SE7221BK1E. 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 256 MB. Therefore, the minimum main memory
configuration is 1 x 256 MB or 256 MB. The largest size DIMM supported is 2 GB however, the
maximum main memory configuration is 4 GB implemented by 4 x 1 GB or 2 x 2 GB DIMMs.

ƒ
The maximum memory capacity is 4 GB
Note* Although the Intel® Server Board SE7221BK1-E supports a maximum memory
capacity of 4 GB, system resources consume roughly 750 MB of physical memory in the
maximum memory configuration. As a result, when 4 GB of memory is used, the amount of
memory made available to the operating system is significantly lower than 4 GB; roughly
3200 MB. THIS IS ONLY AN ISSUE WHEN 4 GB OF MEMORY IS USED. A memory
configuration of less than 4 GB will not be susceptible to this issue. Please refer to Intel®
Technical Advisory TA 719-01 on the support web site located at
http://support.intel.com/support/motherboards/server/SE7221BK1E.
ƒ
The minimum memory capacity is 256 MB via 1 x 256 MB DIMM module
3.2.1.2
Memory Configuration
The memory interface between the GMCH and the DIMMs is 64-bit (non-ECC) or 72-bit (ECC)
wide interface.
There are two banks of DIMMs, labeled 1 and 2. Bank 1 contains DIMM socket locations
DIMM_1A and DIMM_2A. Bank 2 contains DIMM socket locations DIMM_1B and DIMM_2B.
The sockets associated with each bank or “channel”, are located next to each other and the
DIMM socket identifiers are marked on the baseboard silkscreen, near the DIMM socket. Bank 1
is associated with Memory Channel A while Bank 2 is associated with Memory Channel B.
When only two DIMM modules are being used, the population order must be DIMM_1A,
DIMM_1B to ensure dual channel operating mode.
To reiterate: In order to operate in Dual Channel Dynamic Paging Mode, the following conditions
must be met:
•
•
2 identical DIMMs are installed, one each in DIMM_1A and DIMM_1B
4 identical DIMMs are installed (one in each socket location)
Installing only 3 DIMMs is not supported. Do not use DIMMs that are not “matched”
(same type and speed). Use of identical memory parts is always the preferred method.
See Table 2 and Figure 2 on the following page for reference.
The system design is free to populate or not to populate any rank on either channel, including
either degenerate single channel case.
DIMM and memory configurations must adhere to the following:

4. The Intel® E7221 Chipset
The Intel® Server Board SE7221BK1-E is designed around the Intel® E7221 chipset. The
chipset provides an integrated I/O bridge and memory controller, and a flexible I/O subsystem
core (PCI Express*). The chipset consists of three primary components:
ƒ
GMCH: Graphics Memory Control Hub. The GMCH accepts access requests from the
host (processor) bus and directs those accesses to memory or to one of the PCI buses.
The GMCH 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 GMCH also accepts inbound requests from the ICH6R. The GMCH is
responsible for generating the appropriate controls to control data transfer to and from
memory.
The Intel® E7221 GMCH comes with an integrated high performance graphics media
accelerator (Intel® GMA 900) and supports one x8 port configuration PCI-E interface.
Maximum theoretical peak bandwidth on each x8 PCI Express* interface of 2.5 GB/s in
each direction simultaneously, for 5 GB/s per port.
ƒ
ICH6R: I/O Controller Hub 6R. The ICH6R controller has several components. It
provides the interface for a 32-bit/33-MHz PCI bus. The ICH6R can be both a master
and a target on that PCI bus. The ICH6R also includes a USB 2.0 controller and an IDE
controller. The ICH6R is also responsible for much of the power management functions,
with ACPI control registers built in. The ICH6R also provides a number of GPIO pins and
has the LPC bus to support low speed legacy I/O.
The GMCH and ICH6R chips provide the pathway between processor and I/O systems.
The GMCH 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 PCI-E segments, the GMCH communicates with the PCI-E
Devices (add-in card, on board devices) through the PCI-E interface. If the cycle is
directed to the ICH6R, the cycle is output on the GMCH’s DMI bus. All I/O for the board,
including PCI and PC-compatible I/O, is directed through the GMCH and then through
the ICH6R provided PCI buses.
ƒ
PXH: PCI-X Hub The PXH hub is peripheral chips that perform PCI bridging functions
between the PCI Express* interface and the PCI bus. The PXH contains two PCI bus

interfaces that can be independently configured to operate in PCI (33 or 66 MHz), PCI-X
Mode1 (66,100,133), for either 32 or 64 bits.
4.1.1
GMCH Memory Architecture Overview
The GMCH supports a 72-bit wide memory sub-system that can support a maximum of 4 GB of
DDR2 memory using 1 GB DIMMs. This configuration needs external registers for buffering the
memory address and control signals. The four chip selects are registered inside the GMCH and
need no external registers for chip selects.
The memory interface runs at 400/533MT/s. The memory interface supports a 72-bit wide
memory array. It uses seventeen address lines (BA [2:0] and MA [13:0]) and supports 256 Mb,
512 Mb, 1 Gb 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.
4.1.1.1
DDR2 Configurations
The DDR2 interface supports up to 4 GB of main memory and supports single- and double-
density DIMMs. The DDR2 can be any industry-standard DDR2. The following table shows the
DDR2 DIMM technology supported.

Graphics Memory Controller Hub (GMCH)
The GMCH is a 1210-ball FC-BGA device and uses the proven components of previous
generations like the Intel® Pentium® 4 processor bus interface unit, the hub interface unit, and
the DDR2 memory interface unit. In addition, the GMCH incorporates an integrated high
performance graphics media accelerator and a PCI Express* interface. The PCI Express*
interface allows the GMCH to directly interface with the PCI Express* devices (like PXH/PXHD).
The GMCH also increases the main memory interface bandwidth and maximum memory
configuration with a 72-bit wide memory interface.
The GMCH integrates the following main functions:

The Intel® E7221 GMCH includes an integrated graphics engine that supports standard SVGA
drivers with analog display capabilities. 8 MB of memory is pre-allocated in the main memory to
support the internal graphical device when less than 4 GB of physical memory is installed.
However, when the maximum of 4 GB of memory is installed, onboard system resources such
as video consume a considerable amount of memory, leaving just above 3 GB of available
memory for the operating system. Details of this issue have been communicated via the
Technical Advisory TA_719-01 which can be found at:

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 is disabled by default in BIOS Setup when
an off-board video adapter is detected in either the PCI-E or PCI slots.
5.3 Network Interface Controller (NIC)
The Intel® Server Board SE7221BK1-E supports two 10Base-T/100Base/1000Base-T
(82541PI controller) network interfaces. One is through ICH6R directly, and another one is
through PXH (SE7221BK1LX sku only).
The Intel® 82541PI Gigabit Ethernet is a single, compact component with an integrated Gigabit
Ethernet Media Access Control (MAC) and physical layer (PHY) functions. For desktop,
workstation and mobile PC Network designs with critical space constraints, the Intel® 82541PI
allows for a Gigabit Ethernet implementation in a very small area that is footprint compatible
with current generation 10/100 Mbps Fast Ethernet designs. The Intel® 82541PI integrates
fourth generation gigabit MAC design with fully integrated, physical layer circuitry to provide a
standard IEEE 802.3 Ethernet interface for 1000BASE-T, 100BASE_TX, and 10BASE-T
applications (802.3, 802.3u, and 802.3ab). The controller is capable of transmitting and
receiving data at rates of 1000 Mbps, 100 Mbps, or 10 Mbps. In addition to managing MAC and
PHY layer functions, the controller provides a 32-bit wide direct Peripheral Component
Interconnect (PCI) 2.3 compliant interface capable of operating at 33 or 66MHz.
5.3.1
NIC Connector and Status LEDs
The NICs drive two LEDs located on each network interface connector.
For the NIC 1 connector, the green LED indicates network connection when on, and
Transmit/Receive activity when blinking. The yellow LED indicates 1000-Mbps operation when
lit, the green LED indicates 100-Mbps operation when lit and 10-Mbps when off.

SE7221BK1-E Technical Product Specification
For the NIC 2 connector (SE7221BK1LX sku only), the yellow LED indicates network
connection when on, and Transmit/Receive activity when blinking. The orange LED indicates
1000-Mbps operation when lit, the green LED indicates 100-Mbps operation when lit and 10-
Mbps when off.
5.4 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 ICH6.
5.4.1
Legacy Interrupt Routing
For PC-compatible mode, the ICH6 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 ICH6R contains
configuration registers that define which interrupt source logically maps to I/O APIC INTx pins.
The ICH6 handles both PCI and IRQ interrupts. The ICH6R translates these to the APIC bus.
The numbers in the table below indicate the ICH6R PCI interrupt input pin to which the
associated device interrupt (INTA, INTB, INTC, INTD, INTE, INTF, INTG, INTH for PCI bus and
PXIRQ0, PXIRQ1, PXIRQ2, PXIRQ3 for PCI-X bus) is connected. The ICH6R I/O APIC exists
on the I/O APIC bus with the processors.

PCI Slot 5 (64b/66M
5.4.2
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.
5.4.2.1
Legacy Interrupt Sources
The table below recommends the logical interrupt mapping of interrupt sources on the board.
The actual interrupt map is defined using configuration registers in the ICH6.

Serialized IRQ Support
The SE7221BK1-E 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 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.

6. ACPI Implementation
6.1 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 SE7221BK1-E 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.
The S0 sleep state is when everything is on. This is the state that no sleep is
enabled.
S0 Sleep State
S1 Sleep State
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.
S4 Sleep State
S5 Sleep State
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.
6.1.1
Front Panel Switches
The baseboard supports two front panel buttons:
ƒ
ƒ
Power button
Reset button
The power button input (J1J1 pin 11and 13) provides
Power Button Off to On:
FP_PWR_BTN_N signal to the mBMC (PC87431M). mBMC will
output a MBMC_PWR_BTN_N signal to ICH6. If the PWRBTN#
signal of ICH6R is asserted, the assertion causes a wake event.
And then, the SLP_S3 signal of ICH6R will be not asserted. The
SLP_S3 signal will be passed to the PS_ON# signal of ATX power

SE7221BK1-E Technical Product Specification
supply through an inverter, and then transition to an ON state.
The ICH6 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 ICH6 and Super IO to the OFF state.
Power Button On to Off
(Legacy):
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.
Power Button On to Off
(ACPI):
The reset button will generate a hard reset to the system.
The NMI button will force an NMI to the processors.
Reset Button:
NMI Button:
6.1.2
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 15. Supported Wake Events

Under ACPI, the operating system programs the ICH6R and Super IO 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.

9. BIOS Setup Utility
The BIOS Setup utility is provided to perform system configuration changes and to display
current settings and environment information.
The BIOS Setup utility stores configuration settings in system non-volatile storage. Changes
affected by BIOS Setup will not take effect until the system is rebooted. The BIOS Setup Utility
can be accessed when prompted during POST by using the F2 key.
9.1 Localization
The BIOS Setup utility uses the Unicode standard and is capable of displaying setup forms in
English, French, Italian, German, and Spanish. BIOS supports these languages for console
strings as well.
9.2 Console Redirection
BIOS Setup is functional via console redirection over various terminal standards emulation.
This may limit some functionality for compatibility, e.g., usage of colors or some keys or key
sequences or support of pointing devices.
9.3 Configuration Reset
There are different mechanisms for resetting the system configuration to default values. When
a reset system configuration request is detected, the BIOS will load the default system
configuration values during the next POST.
A reset system configuration request can be generated by moving the Clear CMOS jumper.
9.4 Keyboard Commands
The Keyboard Command Bar supports the following keys:
Table 39. BIOS Setup Keyboard Command Bar Options
Key

Description
Enter Execute Command The Enter key is used to activate sub-menus when the selected feature is a sub-menu,
or to display a pick list if a selected option has a value field, or to select a sub-field for
multi-valued features like time and date. If a pick list is displayed, the Enter key will
undo the pick list, and allow another selection in the parent menu.

The ESC key provides a mechanism for backing out of any field. This key will undo the
pressing of the Enter key. When the ESC key is pressed while editing any field or
selecting features of a menu, the parent menu is re-entered.
When the ESC key is pressed in any sub-menu, the parent menu is re-entered. When
the ESC key is pressed in any major menu, the exit confirmation window is displayed
and the user is asked whether changes can be discarded. If “No” is selected and the
Enter key is pressed, or if the ESC key is pressed, the user is returned to where they
were before ESC was pressed without affecting any existing any settings. If “Yes” is
selected and the Enter key is pressed, setup is exited and the BIOS continues with
POST.
Select Item
The up arrow is used to select the previous value in a pick list, or the previous options
in a menu item's option list. The selected item must then be activated by pressing the
Enter key.

The plus key on the keypad is used to change the value of the current menu item to the
next value. This key scrolls through the values in the associated pick list without
displaying the full list. On 106-key Japanese keyboards, the plus key has a different
scan code than the plus key on the other keyboard, but will have the same effect.
F9
Pressing F9 causes the following to appear:
Load Setup Defaults?
[OK]
[Cancel]
If “OK” is selected and the Enter key is pressed, all setup fields are set to their default
values. If “Cancel” is selected and the Enter key is pressed, or if the ESC key is
pressed, the user is returned to where they were before F9 was pressed without
affecting any existing field values.

SE7221BK1-E Technical Product Specification
If you chose to “Save Custom Defaults,” after the new BIOS is flashed, you can restore your
settings from the “Load Custom Default” option.
9.6.1.2
Obtaining the Upgrade Utility
You can upgrade to a new version of the BIOS using the new BIOS files and the BIOS upgrade
utility. You can obtain the BIOS upgrade file and the utility from the Intel Customer Support Web
site: http://support.intel.com/support/motherboards/server/SE7221BK1-E.
9.6.1.3

9.6.2
Flash Architecture and Flash Update Utility
The flash ROM contains system initialization routines, the BIOS Setup Utility, and runtime
support routines. The exact layout is subject to change, as determined by Intel. A 64 KB user
block is available for user ROM code or custom logos. The flash ROM also contains initialization
code in compressed form for on-board peripherals, like SCSI, NIC and video controllers. The
flash ROM also contains support for the Rolling single boot BIOS update feature.
The complete ROM is visible, starting at physical address 4 GB minus the size of the flash ROM
device. The Flash Memory Update utility loads the BIOS image minus the recovery block to the
secondary flash partition, and notifies the BIOS that this image should be used on the next
system re-boot. Because of shadowing, none of the flash blocks are visible at the aliased
addresses below 1 MB.
9.6.3
Rolling BIOS and On-line updates
The Online Update nomenclature refers to the ability to update the BIOS while the server is
online, in operation, as opposed to having to put the server out of operation while doing a BIOS
update. The Rolling BIOS nomenclature refers to the capability for having two copies of BIOS,
viz. the one in use, and the other to which an updated BIOS version can be written. When
ready, the system can roll forward to the new BIOS. In case of a failure with the new version,
the system can roll back to the previous version.
While the exact nature of hardware changes for the support of on-line update / rolling BIOS are
out of scope of this document, BIOS relies on specialized hardware and additional flash space
for this. Flash is divided into two partitions, viz. primary and secondary. The active partition
from which the system boots shall be referred to as the primary partition. The AMI FLASH
update suite and Intel On-line updates preserve the existing BIOS image on the primary
partition. BIOS updates are diverted to the secondary partition. After the update, a notification
flag will be set. During the subsequent boot following BIOS update, system will continue to
attempt to boot from primary BIOS partition. On determining that a BIOS update occurred in the
previous boot, system will attempt to boot the new BIOS. If a failure happens, specialized
hardware will switch back to the BIOS on the other partition, thus affecting a “Roll Back”.

9.6.3.1
Recovery Mode
Three conditions can cause the system to enter recovery mode. Pressing a hot-key, setting the
recovery jumper, and damage to both partitions of the ROM image will cause the system to
enter recovery and update System ROM without the boot-block.
•
BIOS Recovery
The recovery disk must include the BIOS image file AMIBOOT.ROM. The 2 MB
AMIBOOT.ROM file may be used on a 2.88MB floppy media (to go with a 2.88 MB legacy or
USB floppy device), a USB mass storage device (i.e. a USB disk on key, must be USB 1.1
or 2.0 compliant), a USB CDROM (USB 1.1 or 2.0 compliant), an ATAPI mass storage
device, or an ATAPI CDROM or DVD.
The recovery mode procedure is as follows:
1) Insert the Recovery media with AMIBOOT.ROM into the system as appropriate
based on whatever device is used.
2) Power on system, and when progress code E9 is displayed on port 80h,the system
will detect the disk.(if there is no image file present, the system will cycle through
progress code F1 to EF.)
3) When F3 is displayed on port 80h, the system will read the BIOS image file.
4) The screen will display flash progress and show if NVRAM and CMOS have been
destroyed.
5) When recovery mode is complete, the system will halt and the system can be
powered off.
NOTE: There are three different hot-keys that can be invoked:
<Ctrl+Home> - Recovery with CMOS destroyed and NVRAM preserved.
<Ctrl+PageDown> - Recovery with both CMOS and NVRAM preserved.
<Ctrl+PageUp> - Recovery with both CMOS and NVRAM destroyed.
•
Multi-Disk Recovery
With this new feature the System Recovery can be made from Multiple Floppy Disks to
support ROM image greater than 1MB.
Usage:
1) Use the SPLIT.EXE utility to split the ROM image.
Execute the following command at the command prompt:
split <File Name To Be Split> <New File Name> <File Size in KB>
For Example:
C:\split AMIBOOT.ROM AMIBOOT 1024
2) The above command will create the files of sizes 1MB each (1024 KB) with names
AMIBOOT.000, AMIBOOT.001... and so on, depending upon the AMIBOOT.ROM file
size.
3) Load the first disk AMIBOOT.000
Revision 1.3

SE7221BK1-E Technical Product Specification
4) After reading the file it increments the file extension and then searches for
AMIBOOT.001 in the same floppy.
5) If doesn't find the file in the floppy it will beep for once (1sec) and search again.
6) If it finds the first file and if it needs more files it will increment the file extension and
searches again for AMIBOOT.002 this time it beeps 2 times (each beep 1sec long and
with 0.5sec gap)
7) This continues until the total file size read is equal to the ROM image size.
Summary of Beep codes
Beep Code List:
This uses the standard beep codes used by AMI Core8 for Recovery with some additional
codes. They are… (each beep is 1sec long with 0.5sec gap)
1) 1 long beep
2) 2 long beeps
3) 3 long beeps
Insert for AMIBOOT.001 File
Insert for AMIBOOT.002 File
Insert for AMIBOOT.003 File
Limitations:
1) Maximum Files supported 1000 files (AMIBOOT.000 to AMIBOOT.999)
•
Manually Recovering the BIOS
A BIOS recovery can also be manually initiated. This option would be used only when the
BIOS is corrupt, but the ROM checksum error does not occur during POST. To manually
initiate a BIOS recovery, use the following steps:
1) Power down and unplug the system from the AC power source.
2) Move the recovery jumper at J1F2 from the storage position at pins 9 and 10 to
cover pins 10 and 11. See the figure below.
3) Insert the Crisis Recovery Diskette into the A: diskette drive.
4) Plug the system into the AC power source and power it on.
5) A blue screen will be displayed and the recovery process will automatically run. The
system will continue to beep throughout the recovery process. The recovery process
is complete when the beeping stops.
6) Remove the diskette.
7) Power down and unplug the system from the AC power source.
8) Move the BIOS recovery jumper at J1F2 back to the original position, covering
storage pins 9 and 10.

BIOS Event Log
The BIOS will output the current boot progress codes on the video screen. Progress codes are
32 bit quantities plus optional data. The 32 bit numbers include Class, subclass and Operation
information. Class and subclass point to the type of the hardware that is being initialized, where
as the Operation field represents the specific initialization activity. Based upon the data bit
availability to display Progress Code, a progress code can be customized to fit the data width.
The higher the data bit, higher the granularity of information, which could send on the progress
port. The progress codes may be reported by system BIOS or option ROMs.
The Response section in following table is divided in 3 different types:
•

•
Warning – The message is displayed on screen and error is logged in SEL. System will
continue booting with degraded state. User may want to replace erroneous unit
Pause – The message is displayed on screen and user input is required to continue.
User can take immediate corrective action or can choose to continue booting.
Halt – System cannot boot unless error is resolved. User needs to replace faulty part
and restart the system.

9.8 Diagnostic LEDs
All port 80 codes are displayed using the Diagnostic LEDs found on the back edge of the
baseboard. The diagnostic LED feature consists of a hardware decoder and four dual color
LEDs. During POST, the LEDs will display all normal POST codes representing the progress of
the BIOS POST. Each code will be represented by a combination of colors from the four LEDs.
The LEDs are capable of displaying three colors: Green, Red, and Amber. The POST codes are
divided into two nibbles, an upper nibble and a lower nibble. Each bit in the upper nibble is
represented by a Red LED and each bit in the lower nibble is represented by a green LED. If
both bits are set in the upper and lower nibbles then both Red and Green LEDs are lit, resulting
in an Amber color. If both bits are clear, then the LED is off.
In the below example, BIOS sends a value of ACh to the Diagnostic LED decoder. The LEDs
are decoded as follows:
ƒ
ƒ
Red bits = 1010b = Ah
Green bits = 1100b = Ch
Since the red bits correspond to the upper nibble and the green bits correspond to the lower
nibble, the two are concatenated to be ACh.

Power Timing Requirements
These are the timing requirements for the power supply operation. The output voltages must
rise from 10% to within regulation limits (Tvout_rise) within 5 to 70ms, except for 5VSB - it is
allowed to rise from 1.0 to 70ms. The +3.3V, +5V and +12V output voltages should start to rise
approximately at the same time. All outputs must rise monotonically. The +5V output needs
to be greater than the +3.3V output during any point of the voltage rise. The +5V output must
never be greater than the +3.3V output by more than 2.25V. Each output voltage shall reach
regulation within 50ms (Tvout_on) of each other during turn on of the power supply. Each
output voltage shall fall out of regulation within 400msec (Tvout_off) of each other during turn
off. Refer to the table below for the timing requirements for the power supply being turned on
and off via the AC input, with PSON held low and the PSON signal, with the AC input applied.
