Buttons
Power Button

Under ACPI, the power button action is under the control of the operation system.

• The following is a table of the state transitions in ACPI mode.

Initial Final Comments
Off On Does a normal reboot. Prompts for password if required.
Standby On Restores device states from RAM. Prompts for password if required.
Hibernate On Restores RAM and device states from disk. Prompts for password if

required.

On Standby,

Hibernate(
default) or
Off

. Action depends on OS setting. Can be set to Standby, Hibernate, or
Off(default).

. Note that the Off option is done under the control of the OS, so it is
functionally the same as doing a Start-Shut down but probably quicker.

Power Button Over-ride

Holding down the Power Button for 4 seconds will cause an unconditional transfer to the Off
state without notifying the operating system.

If press power button for less than 4 seconds, the system will enter suspend to RAM or OFF
state according to OS UI setting.

Lid Switch

This section describes the expected behavior of the system when the lid is opened or closed
by the user.

If the system is running under legacy mode:

• Closing the lid will turn off LCD backlight.
If the system is running under ACPI mode:

• The function of lid switch will follow the OS setting in power management (Nothing,
standby, Hibernate or Power off). If standby, the system wakes up when the lid opens. If
nothing, the backlight must still turn off when the lid is closed.

System status indicators

Please refer to Keyboard BIOS specification.

Core BIOS Features

Enhanced IDE Disk Drive Support (EDD)

In addition to AT standard disk drive support, the Phoenix NoteBIOS 4.06 also supports:

• Auto-detection and sizing of all IDE drives.

• Logical Block Addressing(LBA)

• Fast DMA support

• Ultra DMA-33/66/100 support

The CHS translation mode will be used.

Chapter 2-3

Multi Boot

The notebook can support Multi Boot for selecting the boot sequence of hard disk, floppy, CD
ROM, Network Boot in Setup. It identifies all IPL (Initial Program Load) devices in the system
and attempts to boot them in the order specified in Setup.

Quiet Boot

Quiet Boot replaces the customary technical messages during POST with a more visually
pleasing and comfortable display (OEM Logo screen). During POST, right after the
initialization of VGA, The notebook displays an illustration called the OEM screen during
system boot instead of the traditional POST screen that displays the normal diagnostic
messages.

The OEM Logo screen stays up until just before the operating system loads unless:

• Press <Esc> to change the boot order.

• Press <F2> to enter Setup. (When pressed, need to show “Entering Setup…”)

• Press <F12> to boot from LAN (When pressed, need to show “Booting from LAN…”)

• Whenever POST detects a non-terminal error, it switches to the POST screen near the

end of POST, just prior to prompting for a password.

• If the BIOS or an option ROM requests keyboard input, the system switches over to the
POST screen with prompts for entering the information. POST continues from there with
the regular POST screen.

New Interrupt 15h extensions

The BIOS must support the recently defined standard INT 15 extensions:

Big Memory

Big memory support that can reporting greater than 64 megabytes of RAM. The notebook
supports the INT 15h big-memory reporting functions of E801h, E881h, and E820h. This
feature reports all available extended memory (both below and above the 64MB limit) using
both a real mode (E801h) and a 32-bit protected mode (E881h) interface. Operating systems
can access the real-mode interface through the standard INT 15h call. They can access the
protected-mode interface through a 32-bit interrupt call, much like the EISA protected-mode
interface. The Microsoft-defined E820h function returns a complete memory map through a
series of repeated calls.

Boot Block

The Flash ROM used in many systems today offer the customer the advantage of
electronically reprogramming the BIOS without physically replacing the BIOS ROM. This
advantage, however, does create a possible hazard: power failures or fluctuations that occur
during updating the Flash ROM can damage the BIOS code, making the system unbootable.
To prevent this possible hazard, many Flash ROM include a special non-volatile region that
can never be erased. This region, called the boot block, contains a fail-safe recovery routine.
If the boot block finds corrupted BIOS, it prompts the end user to insert a diskette, from which
it loads several files that replace the corrupted BIOS on the Flash ROM with an uncorrupted
one.

Plug-n-Play (PnP) Support

To achieve the goal of PnP, a POST conflict detection and resolution (CDR) module, and a
run-time services module will be integrated into the system BIOS.

The PnP runtime service module includes multiple interfaces so that the system can support
the current DOS/Win3.1 non-PnP drivers, as well as Win95 operating system that include
specific support for the PnP BIOS specification.

Chapter 2-4

Security Features

Security features to be supported are passwords, electronic serial number, PC identification
string.

The Electronic Serial Number provides a unique way of identifying an individual notebook.
PC Identification strings allow the user or administrator to personalize the notebook for asset

tracking or identification if it is lost.
The Passwords, Serial Number, and PC Identification strings are to be stored in EEPROM.

2 Level Passwords

The notebook supports two levels of password protection. The password support consists of a
User Password and an Administrator Password. They each contain up to eight characters,
and are stored in EEPROM. Using the administration password to enter the setup utility allows
the user to access all the configurable fields. Whereas using the user password only allows
the user to configure a limited number of fields.

When the password is enabled, the notebook may display a suitable password prompt on the
main display in the following situations:.

• Turning on from off states. (No BIOS suspend/resume password)

• Entering to Setup.

The User will attempt to enter a password, then press ENTER. If the User fails to enter the
password in three tries the system will be halt.

User Password

The user can choose:

• The password will never be required

• Be required to boot.

• The user password may not be set unless the administrator password is set. If the user

wishes to only have one password then the administrator password is used.

Administrator Password

There are three primary uses for the Administrator Password:

• Protect users from changing system configuration that could cause the notebook to
malfunction.

• As the users password if only a single password is desired.

Passwords and Setup

There are individual checkbox items in Setup to allow the user to specify when to require a
password. The wording of these options should be:

Password Required to:
Boot [Enabled]

The following table lists the items in the Setup utility which can be modified by the User.

Time & Date
User password

While setting new password, three failures to enter the old password will result in the system
turning off.

Valid Password Characters

Valid Password Characters

Chapter 2-5

• The numbers 0 to 9.

• The letters A to Z (not case sensitive).

The password is stored as scan codes.

Electronic Serial Number

The electronic serial number is a ten (10) byte string which matches the manufacturing serial
number on the bottom of the notebook. The BIOS must display the electronic serial number in
the boot screen and in Setup. The format of the line should be

Serial Number: SSSSSSSSSS
where SSSSSSSSSS is the electronic serial number. The format of the serial number is:
CCYWWNNNNN
Where
CC is a two character country code (TW for Taiwan).
Y is the year of manufacture (7 = 1997, 8 = 1998, etc.)
WW is the week of manufacture (1 to 52)
NNNNN is the unit number (see below).
Unit number is a number from 00000 to 99999 and is incremented for each unit produced.

The unit number is reset at the beginning of each week. Before displaying the serial number,
the BIOS must check for the special
number is detected, the BIOS should display the message:

INVALID ELECTRONIC SERIAL NUMBER
ENTER THE SERIAL NUMBER NOW:
The BIOS must then force the user to enter the serial number and program the entered serial

number into the EEPROM. The BIOS must perform validity checks on the serial number
entered.

System boards sent to service must be preprogrammed with this invalid serial number. This is
to insure that when a service technician swaps a new main board into a system that he/she
sets the serial number to match the serial number of the system.

This same electronic serial number is used for the serial number returned by the SM BIOS.

Software Password Backdoor

Because users occasionally forget their password we need a method of removing the
password for them. This method must involve little risk to the security of the password system
in general.

The method is that the User calls up Customer Support, Support tells them to press some
*special key combination which causes a
to support representative who then use their secret decoder ring to generate a

which they tell the user to type in. This removes (deletes) all passwords (user and

During the password request process, three failed attempts to enter the backdoor password
will also cause system turning off.

The back door password process can only be held on the cold boot.

Thermal management

There are two types of cooling techniques used for thermal management. The first type is
passive cooling where the CPU speed is reduced or other devices power consumption is

Chapter 2-6

reduced in an effort to reduce heat generation. The second type is active cooling where a fan
is turned on to cool the system.

In non-ACPI mode(Legacy Mode), the thermal management is achieved by controlling the fan
depend on the temperature. Besides turning the fan on and off. The system may also be
shut off whenever the temperature can’t be reduced even the fan are spinning in the full
speed. The system will be turned off immediately when it’s over-heating (over 85°C). The fan
will be turned off when temperature is under 65°C. The table below listed the control point of
temperature changes:

Power Management

Introduction

The notebook supports ACPI power management modes. The system will dynamically switch
to ACPI mode for configuration and power management when an ACPI OS is loaded.

System Time-outs

The system Time-outs include the Standby time-out, the Suspend time-out, and the Hibernate
time-out.

System Time-outs are handled by the operating system in ACPI mode. BIOS time-outs must
be disabled. System time-outs are set using the control panel power applet.

System Power Management

The overall system can be in one of five system power states as described below:

Legacy Mode ACPI mode Power Management

Off Mech. Off (G3) All devices in the system are turned off

completely.

Soft Off (G2/S5) OS initiated shutdown. All devices in the system

are turned off completely.

On Working (G0/S0) Individual devices such as the CPU and hard

disk may be power managed in this state.

Standby (S1) CPU in Stop Clock state

VGA Standby, turn off backlite
PCMCIA Standby
Audio Power Down
Hard Disk Spin Down motor
Super I/O Low Power Mode

Suspend to RAM (S3) CPU set power down

VGA Suspend
PCMCIA Suspend
Audio Power Down
Hard Disk Power Down
CD-ROM Power Down
Super I/O Low Power mode

Save to Disk (S4) Also called Hibernate state. System Saves all

system states and data onto disk prior to power
off the whole system.

Chapter 2-7

Device Power Management

The device specific power management supported by this notebook includes the CPU and the
hard disk.

CPU power management

• ACPI mode

The operating system detects when the system is idle and places the CPU in one of the 3
CPU low power states (C1, C2 or C3) depending on how much latency it believes the
system can afford.

The C1 state is simply the CPU halt instruction. The C2 state is the CPU stop grant state.
The C3 state is the CPU stop clock state. The CPU stays in this state until an interrupt
occurs.

Hard Disk

• ACPI mode

Newer OSes use the spin down timer of the hard drive to set time-outs. The user can sets
the hard disk spin down time-out in the control panel power applet.

System Wake Up Sources

The table below lists the wake up events for all low power states:
Events S1 S3 S4 Process required

Critical low battery - - - -

Field ‘Process Required’ identifies that further process for the occurred events must be
processed during wake up or resume procedure.

*1: Hot keys are not wake up source of standby, suspend to RAM and Hibernate states.
*2: Activity of the USB device is dependent on the driver support.

Power Button

The power button will wake the system from any low power state as described in the Power
Button section.

Real Time Clock Alarm

The Real Time Clock alarm interrupt will wake the system from standby, suspend.

Power Management – ACPI

Introductions

The Advanced Configuration and Power Interface (ACPI) is a well-specified power
management and configuration mechanism. It evolves the existing collection of power
management codes, APM, PnP BIOS, ..etc.

Power State Transition Diagram

The state transition diagram is identical to the one in APM mode.

Time-outs while On AC Power

OS determines the behavior of the feature.

Embedded controller

The keyboard controller will act as the ACPI embedded controller and support the ACPI EC
protocol and interface.

SCI/SMI events

All ACPI OS controllable events will be triggered as SCI. Otherwise SMI will be triggered.

PC2001

The notebook must meet Microsoft Logo requirements in accordance with the PC2001 Design
Guide and the Microsoft Logo test programs.

Miscellaneous Features

Single BIOS ROM

The system BIOS and Keyboard BIOS share one single flash ROM. The size of the flash
ROM is 512KB.

USB Support

This feature allows the use of a USB keyboard to access BIOS Setup and to be used in DOS
without additional drivers.

IDE interface

The IDE device supported master channel.

Flash utility – one BIOS ROM only

The flash utility can be used to program both system and keyboard BIOS at the same time.

Chapter 2-9

EEPROM

There is one EEPROM which is used to store many important system and user data in the
notebook The size of the EEPROM is 2K bytes.

Password Protection

Password and Security support will be implemented in this model. See the PhoenixBIOS 4.0
User Manual for sample screen and the description of Password and Security support.

VGA Support

This section describes the expected behavior when a video monitor is connected to the VGA
port on the notebook or port replicator.

The BIOS will use both of the RGB and pin 11 methods to determine the presence of an
external VGA monitor. Either case meet will indicate an external VGA monitor is present.

The BIOS setup utility will have a menu for setting up the behavior of the external VGA port
according to user preference. There are two settings:

Setting 1, AUTO: Auto-select External VGA if attached(CRT only), LCD if external not
attached.

Setting 2, BOTH: Both External VGA and LCD always on.
When setting 1 is selected the BIOS will automatically turn the internal display off and the

external monitor on, whenever an external monitor is detected. Otherwise it will enter LCD
only mode (with the backlite off if the cover lid is closed). This means that the BIOS must
check for the external video being present during POST; on resume from standby, on resume
from suspend to RAM, on resume from hibernate; on warm dock, on hot dock, on hot undock,
and on warm undock.

When setting 2 is selected, the BIOS will always turn on both the internal display and external
monitor regardless of whether an external monitor is detected.

The hot key for switching the external video (Fn + F5) must only make a temporary change. It

′

must not change the user
external video port. Also the hot key must not check to see if an external monitor is detected
before switching to external only mode. It should just toggle between internal only, both, and
external only (without regard to monitor detect). The hot key setting will not survive suspend
to RAM, hibernate. In these cases the mode should be set back to the setting stored in
CMOS.

s preference in CMOS, it will just change the current state of the

Internal Pointing Device Support

Added a new BIOS setup to enhance the PS/2 pointing devices

PS/2 Pointing Devices:

Auto-Selected: Disable internal pointing devices if external PS/2 mouse is present.

Simultaneous:

• If an external PS/2 mouse is detected, it will be enabled. If USB mice are detected, they
will be enabled as well. If an external mouse contains a third mouse button, it will function
as expected.

• Double click the Mouse icon in the Windows2000/XP Control Panel to adjust pointer
speed, double click speed, right-handed versus left-handed button settings, and pointer
appearance. The settings in this applet apply to all the external and internal pointing
devices in the system. Except as described below, there are no individual pointing device
adjustments available.

The internal pointing device is always enabled. Any external pointing device

connected will also be enabled at the same time.

Chapter 2-10

• Tapping (or double tapping) on the TouchPad is equivalent to a single (or double) left
mouse click. The Synaptics TouchPad driver will be available on the hard drive and the

customer may choose to manually install it. The Synaptics TouchPad driver should only be
installed after first selecting Touch pad only in BIOS Setup.

• Hold down center button of external PS/2 mouse: While holding down the center button of
an external mouse, move the mouse. This will cause the window to move. If the center
button is not held down, all pointing devices function normally.

• Use TouchPad: The TouchPad is locked in as the Scrolling or Magnifying Glass device.
Sweeping across the TouchPad causes the window to move. The other pointing devices
function normally.
