File format is .PCX OEM logo function will require IEI BIOS service to modify BIOS code.

4. Enhanced SATA Drive Support

BIOS support SATA HDD with IDE and AHCI (Hot Plug) mode. 4.1 Drive with IDE Drive (IDE Mode):

Step 1: Select ATA/IDE Configuration Compatible or [P-ATA/S-ATA] Step 2: Legacy IDE Channels [SATA Pri, PATA Sec]

4.2 HDD only (AHCI Mode): Step 1: Select ATA/IDE Configuration Enhanced or [S-ATA Only] Step 2: Configure SATA as AHCI to support hot plug function.

5 Hard Drive Protection Support 5.1 HDD Write Protection

Quick or Silence Boot Option



Hard Disk Write Protect function in the IDE configuration option to protect data and software security. Enable the function on the drive set up page.

5.2 SMART Monitoring Function SMART (Smart Monitoring, Analysis, and Reporting Technology), it allows BIOS to use the SMART protocol to report server system information over a network. Enable the function in each drive option such as HDD.

6. Customize Boot Device Priority 6.1 BIOS Boot Specification (BBS) Compliant

The BIOS Boot Specification provides the feature, the IPL Priority. The IPL Priority is a user-specified priority of IPL devices that is arranged in Setup.

Step 1: Set up the boot order in the Boot Device Priority Page. Step 2: Select the 1st, 2nd, 3rd, and 4th boot device in the system. They can be HDD, CD-Rom/DVD, and USB removable devices.

6.2 Pop-up Boot Menu Change boot sequence without going into setup. Press F11 when system boot up, the Pop-up Boot Menu will show all available boot devices with out change BIOS set up.

6.3 Boot from SCSI, IDE, ATAPI, USB device or Network

After setting up bootable drives, it will be able to assign the bootable drive. 6.4 For SCSI, IDE, and ATAPI drive

Select the bootable drive in Boot Device Priority under the Boot Page in BIOS. 7. Boot from USB Removable Device

USB stands for Universal Serial Bus within Plug and Play features as populate peripheral interface appliance between human and computers. Due to its implementation convenience, it has been tread as a standard interface and task place into PC widely in nowadays computer operation behavior.

7.1 Benefit of Boot-from-USB Feature Users and system integrators can enable the boot-to-USB feature by using the BIOS setting up procedures. Users can enable or disable booting from USB; they can also customize the USB boot order. The boot order determines the sequence a system



follows when scanning floppy, CD/DVD, hard drives, and now USB drives searching for a bootable device.

7.2 USB Booting Applications

The boot-to-USB feature offers the most enhanced flexibility, convenience and supporting. Generally, it can be classified as several features: 1. Increased flexibility by allowing a computer to boot from an USB interface with

difference drive selection. 2. Convenient switching operating system such as Microsoft Windows or Linux by

booting from external USB drives (USB HDD or USB CD-ROM). 3. Support for replacing, repairing, or recovering data from damaged hard drive image.

With boot-to-USB enabled, the end user has the option to run diagnostic utilities and debug damaged internal system devices through USB-bootable device.

4. An array of mass storage opinion for end users requiring large bootable devices. 7.3 USB Boot Set Up Procedures Step 1: Advanced Page: USB Configuration set up option.

Step 2: Enable Legacy USB Support to enable USB drive in DOS mode.

Step 1



Step 3: Boot Page: Removable drives option to specify the USB removable device Step 4: Boot Device Priority option to set up 1st Boot Device as the USB device.

8. Network Boot (Boot on LAN by PXE protocol) 8.1 PXE: Pre-Boot Execution Environment

PXE is an open industry standard developed by a number of software and hardware vendors. It was initial form Intel with many other major manufactures including 3com, HP, and Dell. PXE works with a network interface card or on board Ethernet device in the PC, and makes as Ethernet boot device. It allows a workstation to boot from a server on a network prior to booting the operating system on the local hard drive. In order to boot on LAN, it requires setting up the PXE server, too.

Step 4 Step 3

Step 2



8.2 PXE Working Process

In addition to PXE on the client PC, there are several PXE server components

designed to work in conjunction with a DHCP server. The network must include a PXE

server. The PXE server can be on the same server as DHCP or on a different server,

so you can add PXE to an existing network without affecting the existing DHCP server

or configuration. The PXE server watches for DHCP discovery requests that include a

special tag identifying the client as a PXE client. If the discovery request includes the

tag, the PXE server replies to the client with configuration information, including the

name of a boot image file. The boot image file is transferred to the client using TFTP,

and this file is then used to boot the client.

PC needs its IP address and IP

address of the boot server. If there

is one, it issues DHCP request

with PXE extension tags

PC needs the filename of the

Network Bootstrap Program,

issues a special DHCP request.

8.3 Advantages for networking booting

1. Booting diskless system, such as thin clients and dedicated systems. 2. Deploying software and OS for new systems. 3. Automating systems maintenance, such as backups. 4. Automating system checking, such as virus scanning. 5. Ensuring security where a guaranteed security system is needed. 6. Lower build cost. Network booting reduces the need for high-cost components like

local hard drives or flash, at the very least, it shrinks the flash footprint and simplifies flash requirements.

7. Pre-OS. Device administrators can setup a “Pre-OS boot” in which devices are booted from a network server before the operating system is loaded from the local hard drive.

8.4 PXE Applications

1. Disaster Recovery. With the proper controls designed into your management application, the managed PC boot Agent can permit devices to boot from the server in a network safe mode if local booting failed.

2. Security. To secure data and eliminate unauthorized Programs. Administrators can use network booting to search an image in networking hard drive.

3. Multi-OS Application, select different bootable image in the networking drive to operate in different operation system.

4. Flexible storage capacity. With network booting, even if the OS and application grow in size, flash requirements don’t increase.

8.5 PXE Configuring

In order to using PXE function in IEI products, there are two steps set up required. One is for local machine BIOS set up for PXE ready. Another one is PXE image host server for hosting bootable images.

TFTP service sends Network Boot

Program file to the PC via TFTP TFTP Data Packets



8.5.1 BIOS Setup in Local client machine Step 1: Using ATX power type to keep LAN alive. Step 2: Power Key Page: Enable Resume on LAN

Step 3: Boot Page: Boot Device Priority option to set up 1st Boot Device as the LAN device.

Step2

Step1



8.5.2 PXE server setup There are 2 ways to build up PXE image host server

I. Windows2000/2003 server version Step1: Setup DHCP and BOOTP service active in the server to assign IP address to client systems. If there were any other server or router with DHCP function, it would only require choosing BOOTP Step 2: Set up TFTP service in the DHCP control panel from administrative tools. Step 3: Uploading image file to the TFTP file server.

II. Third party software Some third party software can provide combine function for DHCP and TFTP service (http://tftpd32.jounin.net/). It can be apply in some small networking environment.

9. User Data Storage area 9.1 SMBIOS (DMI) 2.4 Compliant

System Management BIOS (SMBIOS) / Desktop Management Interface (DMI) - Allows

manufacturers to develop structures to access attributes that are known by the system

BIOS, but have no standard interface to management software. SMBIOS defines this

information in a series of data tables, which the BIOS write into the runtime memory

image. Both AMI and Award provides their own software to modify BIOS customize

data inside. This feature will require BIOS service to add in data.



10. Power Management (PM)

Capacity and lifetime of computer system has improved much more than before.

Nevertheless modern processors consume much more energy than older ones and

each system generates more devices hungry for energy. That's why Power

Management is more important than ever. Much can be achieved applying intelligent

Power Management policies. There are two kind of Power management in BIOS

options; APM and ACPI.

10.1 PM Power Saving Mode Power saving mode is depending on the Away System time.

From Working System to Standby mode; The CPU performance will slow down from full speed status; user can easily wake up computer by moving mouse or press any key on the keyboard. System in Suspend Mode will only keep very low power to keep data, user need to use wake up bottom or key to call back system.

10.2 Advanced Power Management (APM)

Short for Advanced Power Management, an API developed by Intel and Microsoft

that allows developers to include power management in BIOS. APM defines a layer

between the hardware and the operating system that effectively shields the

programmer from hardware details.

10.3 Enable APM function Step1: Power Key Page to select Power Supply Type

Step2: Enable Power Management/APM

10.4 Monitor / Hard Drive Power Saving Function More and more monitors are turn to LCD monitors, in order to increase monitor lifetime, it is recommended to turn off monitor power if away system. APM Configuration provides Video and Hard Drive Standby and Suspend Mode to save power and protect to devices. Standby Mode: Quick resume back to system Suspend Mode: More power saving 10.5 Monitor Video Standby or Suspend Mode Step1: Select Video Power down Mode to Standby or Suspend Mode Step2: Set up Standby or Suspend time out from 1 min to 60 mines. 10.5 Hard Drive Standby or Suspend Mode Step1: Select Hard Disk Power down Mode to Standby or Suspend Mode



Step2: Set up Standby or Suspend time out from 1 min to 60 mines. 10.6 ACPI (Advanced Configuration & Power Interface) Compliant

ACPI (Advanced Configuration and Power Interface) is an industry specification for the efficient handling of power consumption in computers. ACPI specifies how a computer's BIOS, operating system and peripherals communicate with each other about power usage. With ACPI feature support, Operation system support can provide different kind of power management mode

10.6.1 Enable ACPI System Standby function

Step 1: Advance Page: ACPI configuration page to select ACPI Aware O/S to YES. Step 2: Enable General ACPI configuration to S1 Step 3: Advantage ACPI Page to enable ACPI APIC Support for extra devices need IRQ address after 15.



Step 4: Set up power saving mode in operation system. Step 5: Set up turn off monitor or hard drive away time for standby mode Step 6: Set up Hibernate time for save to disk ACPI mode.

11. Serial port Console Redirection

Console redirection allows you to maintain a system from a remote location by re-directing keyboard input and text output through the serial port. Graphic output is not redirected. Console redirection can be used under MS-DOS® for tasks such as setting up a common BIOS configuration or setting up a RAID configuration

11.1 Console Redirection Application

1. System monitor for BIOS configuration 2. Central remote control 3. Support IPMI module for system health monitor and remote

11.2 Minimum Requirement



- An available serial port (COM port) on a client system - This port must not conflict with any other ports on the system. - Available serial port (COM) on the server - For systems with two available serial ports, you can use either the COM 1 or COM 2

port. 11.3 Local System BIOS Setup

Step 1: Advanced Page to select Remote Access Configuration option. Step 2: Enable Remote Access Step 3: Select available COM port Step 4: Select serial port mode by [Bits/sec, Data bit, Parity, and Stop Bit] need to meet with remote connection device spec such as modem speed. Step 5: Select Hardware or software flow control, default in none. Step 6: Select Emulator type Step 7: Enable VT-UTF8 Combo Key Support to support VT-UTF8 emulator.

11.4 Console redirection on the remote system

1. Click the Start button, point to Programs—> Accessories—> Communications, and click HyperTerminal.

2. Enter any name for the new connection and select any icon. Click OK. 3. From the Connect to pull-down menu, select a COM port available on your client

system and click OK. After you have selected an available COM port, the COM port properties window is displayed.

4.



5. Select Bits per second. Console redirection supports 9600, 19.2 K, 57.6 K, or 115.2 K bps.

6. Set Data bits to 8. 7. Set Parity to None. 8. Set Stop bits to 1. 9. Set Flow control to Hardware. Click OK. 10.

11. Reboot System The hyper terminal will show the system boot up page for BIOS set up or DOS command function.

12. Watchdog Timer

The Watchdog Timer is provided to ensure that standalone systems can always



recover from catastrophic conditions that cause the CPU to crash. This condition may have occurred by external EMI or a software bug. When the CPU stops working correctly, Watchdog Timer will either perform a hardware reset (cold boot) or a Non-Mask Interrupt (NMI) to bring the system back to a known state. A BIOS function call (INT 15H) is used to control the Watchdog Timer: INT 15H: AH - 6FH Sub-function: AL - 2: Set the Watchdog Timer's period BL : Time-out value (Its unit--second is dependent on the item "Watchdog Timer unit select" in CMOS setup). You have to call sub-function 2 to set the time-out period of Watchdog Timer first. If the time-out value is not zero, the Watchdog Timer will start counting down. While the timer value reaches zero, the system will reset. To ensure that this reset condition does not occur, calling sub-function 2 must periodically refresh the Watchdog Timer. However, the Watchdog timer will be disabled if you set the time-out value to be zero. A tolerance of at least 10% must be maintained to avoid unknown routines within the operating system (DOS), such as disk I/O that can be very time-consuming. Note: When exiting a program it is necessary to disable the Watchdog Timer, otherwise the system will reset. 12.1 Example program ; INITIAL TIMER PERIOD COUNTER ; W_LOOP: MOV AX, 6F02H ;setting the time-out value MOV BL, 30 ;time-out value is 48 seconds INT 15H ; ; ADD YOUR APPLICATION PROGRAM HERE
