JHT01 Service Manual
3. Core BIOS Features
3.1 Multi Boot
The notebook can support Multi-Boot for selecting the boot sequence of Hard Drive, Removable Devices, CD-ROM/DVD Drive and Network in Setup.
3.2 Quiet Boot
Quiet Boot replaces the customary technical messages during POST with a more visually pleasing and comfortable display (OEM 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 screen stays up until just before the operating system loads unless:
• Pressing <Esc> to switch to the POST screen and the boot process will
continue until the end of POST.
•
Pressing <F2> to enter Setup.
• Pressing <F12> to enter Boot Menu.
•
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 request 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.
3.3 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.

4. Thermal management
Please refer to Keyboard BIOS specification.
5. Power Management for ACPI mode
5.1 Introduction

ACPI mode
2-7
JHT01 Service Manual
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 stops clock state. The CPU stays in this state until an interrupt occurs.
5.4.2 Hard Disk
The operating system uses the spin down timer of the hard drive to set time-outs. The BIOS time-out of the hard disk must be disabled in ACPI mode. The user can sets the hard disk spin down time-out in the control panel power applet.
5.4.3 Display Device
The monitor can be turned off after a period of no activity based on the settings of the OS.
5.4.4 System Wake Up Sources
The table below lists the wake up events for all low power states:
Events S3 S4 S5 Process required
Any key O X X X
Power button O O O X
LAN (On board) O O X O

•
LAN (On board)
The function of waking up the system from standby (DC/AC) / hibernation (AC mode) is supported.
5.4.4.2 Real Time Clock Alarm
The Real Time Clock alarm interrupt will wake the system from Standby (DC/AC) / Hibernation (AC mode)
5.4.4.3 Critical Low Battery
Critical low battery event can wake the system from Standby (DC mode) in ACPI mode.
5.5 Hibernation
To support the hibernate state, the save to disk partition or file will be created by the operating system if the user select to enable the hibernation.
It is the responsibility of the operating system to save the system state to a disk file and restore the system state when it is turned back on.

12.12 Three host interface channels support
12.12.1 Keyboard and mouse interface transfer port
• One channel is dedicated for the keyboard and mouse data transfer (host
address 60h and 64h). The Keyboard and Mouse channel of KBC is compatible to the legacy 8042 host interface. It is base on two registers: Command/Data and Status
•
The EC-FW interrupt generates IRQ1 (Keyboard) and IRQ12 (Mouse) for system.
12.12.2 Power management interface transfer port
Fan 1
RPM
4200
• The other channel is for the power management function (host address 62h
and 66h). The Power Management channel of KBC structure and operation are similar to those of the Keyboard/Mouse channel.
12.12.3 Extra transfer port
• This channel (host address 68h and 6Ch) was created to prevent conflict with
the other channels.
12.13 Support three independent devices through PS/2 channel
simultaneously
• The KBC provides three data transfer channels. Each channel has two quasi-
bidirectional signals that are used for the direct interface to an external keyboard, mouse or any other PS/2 compatible pointing device.
• The three channels are identical and thus allow the connector ports to be
interchangeable.
12.14 Devices PnP configuration
12.14.1 Hot Plug-and-Play
• The KBC watches both external devices, checking if the devices have recently
been plugged in or unplugged. The Hot plug ability of external PS2 devices feature detects the attachment or removal of these devices.
2-33
JHT01 Service Manual
12.14.2 Hot swapping control
• When the device is plugged in, the software automatically initializes the state
of that device, checks port swapping, and setup the KBC to handle dual­device operation. In dual-device operation, the internal device is set in the same state as external device. When the external device is unplugged, the internal device becomes the primary device.
12.15 ACPI EC interface Specification support
12.15.1 ACPI interface support
• The KBC provides support for Advance Configuration and Power Interface
specification (ACPI) Embedded Controller interface.
12.15.2 EC command support
•
The 2nd (Power Management) host interface channel of the KBC is dedicated to this function.
•
All EC commands defined in the ACPI specification - Read/Write, Burst Mode enable/disable and Query command - are supported.
12.16 Internal keyboard change Configuration
12.16.1 US/UK/JP country option
• The KBC supports three country selection by KBD_SEL application for
another country.
•
You can key in KBD_SEL get the syntax for your option at DOS prompt.
e.q. KBD_SEL S US keyboard
KBD_SEL K UK keyboard
KBD_SEL J JP keyboard
12.16.2 Sticky key support
• Press shift key 5 times will enable sticky key function. Turns on Sticky Keys,
which allows you to press a modifier key (CTRL, ALT, or SHIFT), or the windows logo key, and have it remain active until the next time you press a key other then CTRL, ALT, SHIFT, or windows logo key. This is useful for people who have difficulty pressing two keys simultaneously.
12.16.3 Internal Keyboard can support wake-up system to resume S3
•
Press any key with internal keyboard in standby mode, system will resume automatically.

Limited lamp maximum current by DAC_BRIG signal:
When DAC_BRIG voltage is 0V and INV_PWM enables (100%), lamp has max.-limited current.
When DAC_BRIG voltage is 3.3V and INV_PWM enables (100%), lamp has min.-limited current.
When add 1V DAC, the 100% Lamp current will decrease 0.5mA.
DAC_BRIG signal comes from system chipset with internal resistance of 3KΩ.
• Inverter operating frequency should be within specification (45~65kHz) at
max. and min. brightness load.
•
INV_PWM enable implies INV_PWM signal is High level (On duty cycle is 100%). It is a square wave of 150Hz to adjust backlight brightness that is a function of PWM duty cycle. Backlight brightness is maximum value under INV_PWM at 100% and brightness is minimum under INV_PWM at 30%.
• The system interface signals belong to 3.3V.
•
Please make sure open lamp output voltage should be within starting voltage specification.
