Chapter 1: Introduction
1-4 Chipset Overview
The H8DCE serverboard is based on the nVidia nForce Pro 2200/2050 chipset.
The two main components of this chipset (the 2200 and the 2050) both function
as Media and Communications Processors (MCPs). Controllers for the system
memory are integrated directly into the AMD Opteron processors.
2200 Media and Communications Processor
This MCP is a single-chip, high-performance HyperTransport peripheral control-
ler. The 2200 includes a 20-lane PCI Express interface, an AMD Opteron 16-bit
Hyper Transport interface link, a four-port Serial ATA interface, a dual ATA133 bus
master interface, a USB 2.0 interface and support for 32-bit PCI slots. This hub
connects directly to CPU#1 and the 2050 MCP. The GLAN#1 connects directly
to the 2200 MCP.
2050 Media and Communications Processor
The 2050 is pin-to-pin compatible with the 2200. It includes a PCI Express interface
with 20 lanes, an AMD Opteron 16-bit Hyper Transport interface link, and a four-port
Serial ATA interface. The GLAN#2 connects directly to the 2050 MCP.
HyperTransport Technology
HyperTransport technology is a high-speed, low latency point to point link that was
designed to increase the communication speed by a factor of up to 48x between
integrated circuits. This is done partly by reducing the number of buses in the
chipset to reduce bottlenecks and by enabling a more effi cient use of memory in
multi-processor systems. The end result is a signifi cant increase in bandwidth
within the chipset.

H8DCE User’s Manual
1-5 PC Health Monitoring
This section describes the PC health monitoring features of the H8DCE. The
serverboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.
Onboard Voltage Monitors for two CPU cores, Hyper Transport
(1.2V), two memory banks (2.5V), nVidia 2200/2050 chipset (1.5V)
The onboard voltage monitor will scan these voltages continuously. Once a voltage
becomes unstable, it will give a warning or send an error message to the screen.
Users can adjust the voltage thresholds to defi ne the sensitivity of the voltage moni-
tor. Real time readings of these voltage levels are all displayed in BIOS.
Fan Status Monitor with Firmware/Software Speed Control
The PC health monitor can check the RPM status of the cooling fans. The onboard
fans are controlled by thermal management via BIOS.
CPU Overheat/Fan Fail LED and Control
This feature is available when the user enables the CPU overheat/Fan Fail warning
function in the BIOS. This allows the user to defi ne an overheat temperature. When
this temperature is exceeded or when a fan failure occurs, then, the Overheat/Fan
Fail warning LED is triggered.
Auto-Switching Voltage Regulator for the CPU Core
The 3-phase-switching voltage regulator for the CPU core can support up to 80A and
auto-sense voltage IDs ranging from 0.875 V to 1.6V. This will allow the regulator
to run cooler and thus make the system more stable.
1-6 Power Confi guration Settings
This section describes the features of your serverboard that deal with power and
power settings.
Microsoft OnNow
The OnNow design initiative is a comprehensive, system-wide approach to system
and device power control. OnNow is a term for a PC that is always on but appears
to be off and responds immediately to user or other requests.
1-10
Chapter 1: Introduction
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blinking
to indicate that the CPU is in suspend mode. When the user presses any key, the
CPU will wake-up and the LED will automatically stop blinking and remain on.
BIOS Support for USB Keyboard
If a USB keyboard is the only keyboard in the system, it will function like a normal
keyboard during system boot-up.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system
suspend button. When the user depresses the power button, the system will enter
a SoftOff state. The monitor will be suspended and the hard drive will spin down.
Depressing the power button again will cause the whole system to wake-up. Dur-
ing the SoftOff state, the ATX power supply provides power to keep the required
circuitry in the system alive. In case the system malfunctions and you want to turn
off the power, just depress and hold the power button for 4 seconds. The power
will turn off and no power will be provided to the serverboard.
Wake-On-LAN (JWOL)
Wake-On-LAN is defi ned as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, up-dates and access
tracking can occur after hours and on weekends so that daily LAN traffi c is kept
to a minimum and users are not interrupted. The serverboard has a 3-pin header
(JWOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has
WOL capability. Wake-On-LAN must be enabled in BIOS. Note that Wake-On-LAN
can only be used with an ATX 2.01 (or above) compliant power supply.
Wake-On-Ring Header (JWOR)
Wake-up events can be triggered by a device such as the external modem ringing
when the system is in the SoftOff state. Note that external modem ring-on can only
be used with an ATX 2.01 (or above) compliant power supply.
1-11
H8DCE User’s Manual
1-7 Power Supply
As with all computer products, a stable power source is necessary for proper and
reliable operation. It is even more important for processors that have high CPU
clock rates of 1 GHz and faster.
The H8DCE accommodates 12V ATX power supplies. Although most power sup-
plies generally meet the specifi cations required by the CPU, some are inadequate.
A 2 amp current supply on a 5V Standby rail is strongly recommended.
It is strongly recommended that you use a high quality power supply that meets
12V ATX power supply Specifi cation 1.1 or above. Additionally, in areas where
noisy power transmission is present, you may choose to install a line fi lter to shield
the computer from noise. It is recommended that you also install a power surge
protector to help avoid problems caused by power surges.
Warning: To prevent the possibility of explosion, do not use the wrong type of
onboard CMOS battery or install it upside down.
1-8 Super I/O
The disk drive adapter functions of the Super I/O chip include a fl oppy disk drive
controller that is compatible with industry standard 82077/765, a data separator,
write pre-compensation circuitry, decode logic, data rate selection, a clock genera-
tor, drive interface control logic and interrupt and DMA logic. The wide range of
functions integrated onto the Super I/O greatly reduces the number of components
required for interfacing with fl oppy disk drives. The Super I/O supports two 360
K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s,
500 Kb/s or 1 Mb/s.
It also provides two high-speed, 16550 compatible serial communication ports
(UARTs), one of which supports serial infrared communication. Each UART in-
cludes a 16-byte send/receive FIFO, a programmable baud rate generator, complete
modem control capability and a processor interrupt system. Both UARTs provide
legacy speed with baud rate of up to 115.2 Kbps as well as an advanced speed
with baud rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Confi guration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through a SMI or SCI function pin. It also features auto power management
to reduce power consumption.
The IRQs, DMAs and I/O space resources of the Super I/O can be fl exibly adjusted
to meet ISA PnP requirements, which support ACPI and APM (Advanced Power
Management).

2-1 Static-Sensitive Devices
Electric Static Discharge (ESD) can damage electronic com ponents. To prevent
damage to your system board, it is important to handle it very carefully. The following
measures are generally suffi cient to protect your equipment from ESD.
Precautions
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing the board from the antistatic
bag.
• Handle the board by its edges only; do not touch its components, peripheral
chips, memory modules or gold contacts.
• When handling chips or modules, avoid touching their pins.
• Put the serverboard and peripherals back into their antistatic bags when not in
use.
• For grounding purposes, make sure your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and
the serverboard.
• Use only the correct type of CMOS onboard battery as specifi ed by the manufac-
turer. Do not install the CMOS onboard battery upside down, which may result
in a possible explosion.
Unpacking
The serverboard is shipped in antistatic packaging to avoid static damage. When
unpacking the board, make sure the person handling it is static protected.
Installation Procedures
Follow the procedures as listed below to install the serverboard into a chassis:
1. Install the processor(s) and the heatsink(s).
2. Install the serverboard in the chassis.
3. Install the memory and add-on cards.
4. Finally, connect the cables and install the drivers.
2-1
H8DCE User's Manual
2-2 Processor and Heatsink Installation
Exercise extreme caution when handling and installing the processor.
!
Installing the CPU Backplates
Two CPU backplates (BKT-0004) are included in the retail box. The backplates
prevent the CPU area of the serverboard from bending and provide a base for at-
taching the heatsink retention modules. To install, begin by peeling off the release
paper to expose the adhesive. On the underside of the serverboard, locate the two
holes on either side of the CPU socket. Attach the adhesive side of the backplate
to the board by inserting the standoffs into the two holes and applying light pressure
so that the backplate sticks to the underside of the board. Repeat for the second
CPU socket. See Figure 2-1.
Always connect the power cord last and always remove it before
adding, removing or changing any hardware components.
Installing the Processor (install to the CPU#1 socket fi rst)
1. Lift the lever on CPU socket #1 until
it points straight up.
2. Use your thumb and your index fi n-
ger to hold the CPU. Locate pin 1 on
the CPU socket and pin 1 on the CPU.
Both are marked with a triangle.
3. Align pin 1 of the CPU with pin 1
of the socket. Once aligned, carefully
place the CPU into the socket. Do not
drop the CPU on the socket, move the
CPU horizontally or vertically or rub the
CPU against the socket or against any
pins of the socket, which may damage
the CPU and/or the socket.
Triangles
2-2
4. With the CPU inserted into the
socket, inspect the four corners of the
CPU to make sure that it is properly
installed and fl ush with the socket.
5. Gently press the CPU socket lever
down until it locks in the plastic tab.
For a dual-processor system, repeat
these steps to install another CPU into
the CPU#2 socket.
Installing the Heatsink Retention Modules
Chapter 2: Installation
Two heatsink retention modules (BKT-0005) and four screws are included in the
retail box. Once installed, these are used to help attach the heatsinks to the CPUs.
To install, position the module so that the CPU backplate standoffs insert through the
holes on the heatsink retention module and the four feet on the module contact the
serverboard. Secure the retention module to the backplate with two of the screws
provided. See Figure 2-1. Repeat for the second CPU socket. Note: BKT-0005
is included for use with non-proprietary heatsinks only. When installing proprietary
heatsinks, only BKT-0004 (CPU backplate) is needed. The BKT-0005 retention
module was designed to provide compatibility with clip-and-cam type heatsinks
from third parties.
Figure 2-1. CPU Backplate/Heatsink Retention Module Installation
Installing the Heatsink
We recommend the use of active type heatsinks (except for 1U systems). Use the
Fan7 header for the CPU1 fan and the Fan8 header for the CPU2 fan due to fan
monitoring and wiring considerations. To install the heatsinks, please follow the
installation instructions included with your heatsink package (not included).

H8DCE User's Manual
2-3 Mounting the Serverboard into a Chassis
All serverboards and motherboards have standard mounting holes to fi t different
types of chassis. Make sure that the locations of all the mounting holes for both
the serverboard and the chassis match. Although a chassis may have both plastic
and metal mounting fasteners, metal ones are highly recommended because they
ground the serverboard to the chassis. Make sure that the metal standoffs click in
or are screwed in tightly.
1. Check the compatibility of the serverboard ports and the I/O shield
The H8DCE serverboard requires a chassis that can support extended ATX boards
of 12" x 13.05" in size. Make sure that the I/O ports on the serverboard align with
their respective holes in the I/O shield at the rear of the chassis.
2. Mounting the serverboard onto the mainboard tray in the chassis
Carefully mount the serverboard onto the mainboard tray by aligning the serverboard
mounting holes with the raised metal standoffs in the tray. Insert screws into all
the mounting holes in the serverboard that line up with the standoffs. Then use a
screwdriver to secure the serverboard to the mainboard tray - tighten until just snug
(if too tight you might strip the threads). Metal screws provide an electrical contact
to the serverboard ground to provide a continuous ground for the system.
2-4 Installing Memory
CAUTION
Exercise extreme care when installing or removing memory modules
to prevent any possible damage.
1. Insert each memory module vertically into its slot, paying attention to the notch
along the bottom of the module to prevent inserting the module incorrectly (see
Figure 2-2). See support information below.
2. Gently press down on the memory module until it snaps into place.
Note: each processor has its own built-in memory controller, so the CPU2 DIMMs
cannot be addressed if only a single CPU is installed. 128 MB, 256 MB, 512 MB,
1 GB, 2 GB* and 4 GB* memory modules are supported. It is highly recommended
that you remove the power cord from the system before installing or changing any
memory modules.
*With Opteron 246 C-stepping CPUs and above.
2-4
Chapter 2: Installation
Support
The H8DCE supports single or dual-channel, registered ECC DDR400/333/266
SDRAM.
Both interleaved and non-interleaved memory are supported, so you may populate
any number of DIMM slots (see note on previous page and charts on following
page). The CPU2 DIMM slots can only be accessed when two CPUs are installed
(however, the CPU2 DIMM slots are not required to be populated when two CPUs
are installed).
Populating two adjacent slots at a time with memory modules of the same size and
type will result in interleaved (128-bit) memory, which is faster than non-interleaved
(64-bit) memory.
Optimizing memory performance
If two processors are installed, it is better to stagger pairs of DIMMs across both
sets of CPU DIMM slots, e.g. fi rst populate CPU1 slots 1A and 1B, then CPU2 slots
1A, and 1B, then the next two CPU1 slots, etc. This balances the load over both
CPUs to optimize performance.
Maximum memory (two CPUs): 32 GB for DDR266 and 16 GB for DDR400/333.
If only one CPU is installed, maximum supported memory is halved (16 GB for
DDR266 and 8 GB for DDR400/333).
Figure 2-2. Side and Top Views of DDR Installation
To Install:
Insert module vertically
and press down until it
snaps into place. The
release tabs should
close - if they do not
you should close them
yourself.
Note the notch in the slot and on the bottom of the DIMM.
These prevent the DIMM from being installed incorrectly.
To Remove:
Use your thumbs to
gently push each release tab outward to
release the DIMM from
the slot.

2-10 Enabling SATA RAID
Now that the hardware is set up, you must now install the operating system and the
SATA RAID drivers, if you wish to use RAID with your SATA drives. The installation
procedure differs depending on whether you wish to have the operating system
installed on a RAID array or on a separate non-RAID drive. See the instructions
below for details.
Serial ATA (SATA)
Serial ATA (SATA) is a physical storage interface that employs a single cable with a
minimum of four wires to create a point-to-point connection between devices. This
connection is a serial link that supports a SATA transfer rate from 150 MBps. The
serial cables used in SATA are thinner than the traditional cables used in Parallel
ATA (PATA) and can extend up to one meter in length, compared to only 40 cm for
PATA cables. Overall, SATA provides better functionality than PATA.
Installing the OS/SATA Driver
Before installing the OS (operating system) and SATA RAID driver, you must decide
if you wish to have the operating system installed as part of a bootable RAID array
or installed to a separate non-RAID hard drive. If on a separate drive, you may
install the driver either during or after the OS installation. If you wish to have the
OS on a SATA RAID array, you must follow the procedure below and install the
driver during the OS installation.
Building a Driver Diskette
You must fi rst build a driver diskette from the Supermicro CD-ROM that was included
with the system. (You will have to create this disk on a computer that is already
running and with the OS installed.) Insert the CD into your CD-ROM drive and
start the system. A display as shown in Figure 2-5 will appear. Click on the icon
labeled "Build Driver Diskettes and Manuals" and follow the instructions to create
a fl oppy disk with the driver on it. Once it's been created, remove the fl oppy and
insert the installation CD for the Windows Operating System you wish to install into
the CD-ROM drive of the new system you are about to confi gure.
2-23
H8DCE User's Manual

Utility program.
Using the nVidia RAID Utility
The nVidia RAID Utility program is where you can defi ne the drives you want to
include in the RAID array and the mode and type of RAID. Two main windows
are shown in the utility. The "Free Disks" window on the left will list all available
drives. Use the arrow keys to select and move drives to the window on the right,
which lists all drives that are to become part of the RAID array.
Once you have fi nished selecting the drives and type of RAID you wish to use for
your RAID array, press the <F7> key. You will be prompted to verify your choice; if
you want to continue with your choices, select "Yes". Note that selecting "Yes" will
clear all previous data from the drives you selected to be a part of the array. You
are then given the choice of making the RAID array bootable by pressing the the
<B> key. After you have fi nshed, press the <Ctrl> and <X> keys simultaneously.
Installing the OS and Drivers
With the Windows OS installation CD in the CD-ROM drive, restart the system.
When you see the prompt, hit the <F6> key to enter Windows setup. Eventually a
blue screen will appear with a message that begins "Windows could not determine
the type of one or more storage devices . . ." When you see the screen, hit the <S>
key to "Specify Additional Device", then insert the driver diskette you just created
2-24

3-1 Troubleshooting Procedures
Use the following procedures to troubleshoot your system. If you have followed all
of the procedures below and still need assistance, refer to the ‘Technical Support
Procedures’ and/or ‘Returning Merchandise for Service’ section(s) in this chapter.
Always disconnect the AC power cord before adding, changing or installing any
hardware components.
Before Power On
1. Check that the onboard Power LED is lit (D25 on the serverboard).
2. Make sure that the 8-pin 12v power connector at JPW1 and the 4-pin connector
at PW3 are both connected to your power supply.
3. Make sure that no short circuits exist between the serverboard and chassis.
4. Disconnect all ribbon/wire cables from the serverboard, including those for the
keyboard and mouse.
5. Remove all add-on cards.
6. Install a CPU and heatsink (making sure it is fully seated) and connect the in-
ternal (chassis) speaker and the power LED to the serverboard. Check all jumper
settings as well.
7. Use the correct type of onboard CMOS battery as recommended by the manufac-
turer. To avoid possible explosion, do not install the CMOS battery upside down.
No Power
1. Make sure that no short circuits exist between the serverboard and the chas-
sis.
2. Verify that all jumpers are set to their default positions.
3. Check that the 115V/230V switch on the power supply is properly set.
4. Turn the power switch on and off to test the system.
5. The battery on your serverboard may be old. Check to verify that it still supplies
~3VDC. If it does not, replace it with a new one.

H8DCE User's Manual
No Video
1. If the power is on but you have no video, remove all the add-on cards and
cables.
2. Use the speaker to determine if any beep codes exist. Refer to Appendix A for
details on beep codes.
NOTE
If you are a system integrator, VAR or OEM, a POST diagnostics
card is recommended. For I/O port 80h codes, refer to App. B.
Memory Errors
1. Make sure that the DIMM modules are properly and fully installed.
2. You should be using registered ECC DDR memory (see next page). Also, it is
recommended that you use the same memory type and speed for all DIMMs in the
system. See Section 2-4 for memory details and limitations.
3. Check for bad DIMM modules or slots by swapping modules between slots and
noting the results.
4. Check the power supply voltage 115V/230V switch.
Losing the System’s Setup Confi guration
1. Make sure that you are using a high quality power supply. A poor quality power
supply may cause the system to lose the CMOS setup information. Refer to Sec-
tion 1-6 for details on recommended power supplies.
2. The battery on your serverboard may be old. Check to verify that it still supplies
~3VDC. If it does not, replace it with a new one.
3. If the above steps do not fi x the setup confi guration problem, contact your vendor
for repairs.
3-2 Technical Support Procedures
Before contacting Technical Support, please take the following steps. Also, note
that as a serverboard manufacturer, we do not sell directly to end-users, so it is

3-3 Frequently Asked Questions
Question: What type of memory does my serverboard support?
Answer: The H8DCE supports up to 32 GB of registered ECC DDR266 or up to
16 GB of registered ECC DDR400/333 interleaved or non-interleaved SDRAM with
two CPUs installed. With only one CPU installed the maximum memory support is
halved. See Section 2-4 for details on installing memory.
Question: How do I update my BIOS?
Answer: It is recommended that you not upgrade your BIOS if you are not experi-
encing problems with your system. Updated BIOS fi les are located on our web site.
Please check our BIOS warning message and the information on how to update
your BIOS on our web site. Also, check the current BIOS revision and make sure
it is newer than your current BIOS before downloading.
Select your mainboard model on the web page and download the corresponding
BIOS fi le to your computer. Unzip the BIOS update fi le, in which you will fi nd the
readme.txt (fl ash instructions), the amifl ash.exe (BIOS fl ash utility) and the BIOS
image (xxx.rom) fi les. Copy these fi les to a bootable fl oppy disk, insert the disk
into drive A and reboot the system. At the DOS prompt after rebooting, enter the
command "amifl ash" (without quotation marks) then type in the BIOS fi le that you
want to update with (xxxx.rom).

H8DCE User's Manual
Question: What's on the CD that came with my serverboard?
Answer: The supplied compact disc has quite a few drivers and programs that will
greatly enhance your system. We recommend that you review the CD and install the
applications you need. Applications on the CD include chipset drivers for Windows
and security and audio drivers.
Question: Why can't I turn off the power using the momentary power on/off
switch?
Answer: The instant power off function is controlled in BIOS by the Power But-
ton Mode setting. When the On/Off feature is enabled, the serverboard will have
instant off capabilities as long as the BIOS has control of the system. When the
Standby or Suspend feature is enabled or when the BIOS is not in control such
as during memory count (the fi rst screen that appears when the system is turned
on), the momentary on/off switch must be held for more than four seconds to shut
down the system. This feature is required to implement the ACPI features on the
serverboard.
Question: How do I connect the ATA133 cable to my IDE device(s)?
Answer: The 80-wire/40-pin high-density ATA133 IDE cable that came with your
system has two connectors to support two drives. This special cable must be used
to take advantage of the speed the ATA133 technology offers. Connect the blue
connector to the onboard IDE header and the other connector(s) to your hard
drive(s). Consult the documentation that came with your disk drive for details on
actual jumper locations and settings.

Chapter 4
BIOS
4-1 Introduction
This chapter describes the AMIBIOS™ Setup utility for the H8DCE. The AMI ROM
BIOS is stored in a fl ash chip and can be easily upgraded using a fl oppy disk-based
program.
Note: Due to periodic changes to the BIOS, some settings may have been added or
deleted and might not yet be recorded in this manual. Please refer to the Manual
Download area of our web site for any changes to BIOS that may not be refl ected
in this manual.
Starting the Setup Utility
To enter the BIOS Setup Utility, hit the <Delete> key while the system is booting-up.
(In most cases, the <Delete> key is used to invoke the BIOS setup screen. There
are a few cases when other keys are used, such as <F1>, <F2>, etc.) Each main
BIOS menu option is described in this manual.
The Main BIOS screen has two main frames. The left frame displays all the options
that can be confi gured. “Grayed-out” options cannot be confi gured. The right frame
displays the key legend. Above the key legend is an area reserved for a text mes-
sage. When an option is selected in the left frame, it is highlighted in white. Often
a text message will accompany it. (Note that BIOS has default text messages built
in. We retain the option to include, omit, or change any of these text messages.)
Settings printed in Bold are the default values.
A "
" indicates a submenu. Highlighting such an item and pressing the <Enter>
key will open the list of settings within that submenu.
The BIOS setup utility uses a key-based navigation system called hot keys. Most
of these hot keys (<F1>, <F10>, <Enter>, <ESC>, <Arrow> keys, etc.) can be used
at any time during the setup navigation process.

H8DCE User's Manual
4-2 Main Menu
When you fi rst enter AMI BIOS Setup Utility, you will see the Main Menu screen.
You can always return to the Main Menu by selecting the Main tab on the top of
the screen with the arrow keys.
The Main Menu screen provides you with a system overview, which includes the
version, built date and ID of the AMIBIOS, the type, speed and number of the pro-
cessors in the system and the amount of memory installed in the system.
System Time/System Date
You can edit this fi eld to change the system time and date. Highlight System Time
or System Date using the <Arrow> keys. Enter new values through the keyboard.
Press the <Tab> key or the <Arrow> keys to move between fi elds. The date must
be entered in DAY/MM/DD/YYYY format. The time is entered in HH:MM:SS format.
Please note that time is in a 24-hour format. For example, 5:30 A.M. appears as
05:30:00 and 5:30 P.M. as 17:30:00.
4-3 Advanced Settings Menu
CPU Confi guration Sub-Menu
GART Error Reporting
This setting is used for testing only.
MTRR Mapping
This determines the method used for programming CPU MTRRs when 4 GB or more
memory is present. The options are Continuous, which makes the PCI hole non-
cacheable, and Discrete, which places the PCI hole below the 4 GB boundary.
IDE Confi guration
Onboard PCI IDE Controller
The following options are available to set the IDE controller status: Disabled will dis-
able the controller. Primary will enable the primary IDE controller only. Secondary
will enable the secondary IDE controller only. Both will enable both the primary and
the secondary IDE controllers. The six controllers listed are for two dual-channel
IDE and eight SATA devices.

Highlight one of the items above and press <Enter> to access the submenu for
that item.
Type
Select the type of device connected to the system. The options are Not Installed,
Auto, CDROM and ARMD.
LBA/Large Mode
LBA (Logical Block Addressing) is a method of addressing data on a disk drive.
In the LBA mode, the maximum drive capacity is 137 GB. For drive capacities of
over 137 GB, your system must be equipped with 48-bit LBA mode addressing.
If not, contact your manufacturer or install an ATA/133 IDE controller card that
supports 48-bit LBA mode. The options are Disabled and Auto.
Block (Multi-Sector Transfer)
Block mode boosts IDE drive performance by increasing the amount of data
transferred. Only 512 bytes of data can be transferred per interrupt if block mode
is not used. Block mode allows transfers of up to 64 KB per interrupt. Select
"Disabled" to allow the data to be transferred from and to the device one sec-
tor at a time. Select "Auto" to allows the data transfer from and to the device
occur multiple sectors at a time if the device supports it. The options are Auto
and Disabled.
PIO Mode
PIO (Programmable I/O) mode programs timing cycles between the IDE drive
and the programmable IDE controller. As the PIO mode increases, the cycle time
decreases. The options are Auto, 0, 1, 2, 3, and 4. Select Auto to allow AMI
BIOS to auto detect the PIO mode. Use this value if the IDE disk drive support
cannot be determined. Select 0 to allow AMI BIOS to use PIO mode 0. It has a
data transfer rate of 3.3 MBs. Select 1 to allow AMI BIOS to use PIO mode 1.
It has a data transfer rate of 5.2 MBs. Select 2 to allow AMI BIOS to use PIO
mode 2. It has a data transfer rate of 8.3 MBs. Select 3 to allow AMI BIOS to
use PIO mode 3. It has a data transfer rate of 11.1 MBs. Select 4 to allow AMI
BIOS to use PIO mode 4. It has a data transfer rate of 16.6 MBs. This setting
generally works with all hard disk drives manufactured after 1999. For other disk
drives, such as IDE CD-ROM drives, check the specifi cations of the drive.
