1.1 Scope

This document define the DHS52 (project name Aphid) engineering specification in EE/SW/ME and

reliability definition.

1.2 Product Objective

DHS52 (project name Aphid ) is the BenQ Joybook series model and its target market is on the consumer

field. And the major EE/ME/SW feature are leveraged Quincy ED2 model to meet short schedule and

variable market environment.

Target Operating Systems

BenQ will offer support for the following operating systems:

 Require Windows XP (Home Edition)
 Require Windows XP (Professional Edition)

System Management BIOS (SMBIOS)

DHS52 BIOS must support the SMBIOS BIOS Specification version 2.3 (formerly DMI
BIOS). Customer requires only the subset of SMBIOS functions and structures that are
listed as required in the SMBIOS specification, and as required by the PC2001
specification.

SMBIOS specification.

Note SMBIOS in DHS52 must provide 32-bit entry table in F000 Segment to be PC99+
compliant, also this is the preferred method, since Plug and Play interface will eventually go
away and new OS do not handle 16-bit interfaces well.

Security

Security features protect the data of machine from unveiled publicly and unauthorized
access. BenQ will provide the security features outlined in this section.
BenQ provides a two-level password security scheme stored in a non-volatile storage device
(EEPROM).

 Supervisor password.
 User Password.

The password, if set, is required to gain access to the Setup utility, and to boot the system.
The difference between the two password levels only exists when executing the Setup utility.

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.
DHS52also provides a H/W solution to reset or bypass password.
Secured data is kept in a non-volatile storage device (EEPROM). The entire data structure of
secured data in the non-volatile storage must be verified with a checksum calculation.
Others follow Third party BIOS’s Security specification.

Serial Number (S/N)

T The Serial Number string will be stored in the secured data area. The S/N will not be
displayed in BIOS SETUP menu. The S/N is an alphanumeric string of 24 bytes in length.
The rule of S/N is: P/N (10 bytes) + Year (1 bytes) + Week (2 bytes) + series No (5 bytes) +
model (6 bytes). The following is an example of the string representation of S/N:
99K0502T0131500001DHS52.

Model ID String (for SLP)

On BenQ System has a specific text string embedded in BIOS ROM F000:FFB0h. It will be
identified the model and BIOS version by diagnostic program and flash utility. The format
is as below:

B0 B1 B2 B3 B4 B5 B6 B7 B8 B9 BA BB BC BD BE BF

System Meter

DHS52 should provide 3 bytes in CMOS and the default value is 0. It will auto count the
hour of usage when boot to OS. The format is Hour(2 bytes): Min(1 byte)
System cannot reset its value.

Debugging

Basic unit problem analysis will be provided through the use of POST and runtime
checkpoint codes output to I/O port 378h.

Auto Dim

The system will support an automatic dimming of the LCD backlight when the AC power
source is NOT available (running on battery power).
The user may always manually increase or decrease the brightness, including to full
maximum setting.

The current user setting of brightness (along with current power source) will be saved, and
the brightness setting will be restored to the user’s set level at the next boot or resume.

Under Ac mode, if user plugs out AC, it will decrease one step automatic. After user plugs
in the AC, it will increase one step. There are two special cases that KBC should take care.

 DC mode and set maximum of brightness

Don’t change the brightness level when AC in. It shouldn’t decrease when user plugs AC

out.

 AC mode and set the minimum of brightness

Don’t change the brightness when AC out. It shouldn’t increase one step when user plugs
AC in again.

Boot Block

DHS52 BIOS provided Crisis mode to support Boot Block function provides a safe
solution to recover system BIOS in case of BIOS code in flash memory is corrupted. There
are two ways to enter Crisis Mode:

 BIOS corrupted, Boot Block function will enter Crisis mode automatically
 Plug Bootblock board into print port to force Boot Block function to enter Crisis mode.

POST
POST Logo

The logo should be displayed on the screen during POST. It is a colored bitmap
(800*600*256 color) and the background should be black. When there is an error
occurred, BIOS closes the logo and switches to text mode to display the error message.
BIOS support ESC key for Popup Boot Menu during POST.

POST Error

If the CMOS checksum is bad, the BIOS should load the default values.

Fast POST

BenQ will comply with the Microsoft Simple Boot Flag Specification v1.0/v2.0. In that
document, two types of boot sequences are defined.

Boot Device Sequence

BIOS will provide the user with the ability to select the devices for attempting to boot an OS.
The user will be able to specify which system device will be attempted 1st, 2nd, and so on.
During Post, user can also use the “ESC” to select the boot device, and user press the “F10”
to enter recovery partition and run recovery program.

The list of possible boot devices sequence will include:

 USB Floppy
 Primary Hard Drive (built-in)
 CD-ROM Drive
 Network (PXE) for built-in LAN

Boot From LAN

The systems of BenQ has the internal LAN card, booting the system from the network
could be done by:

 Specify the network as the first boot device.
 At post, user could change the system boot from network. It depends on Third party

BIOS’s design.

SVID and SSID of PCI device

BIOS should program the Subsystem Vendor ID and Subsystem ID into the PCI
configuration space for each PCI device. The Subsystem Vendor ID will be 17ffh for all
devices. The Subsystem ID will be 058bh.

Keyboard Hot Keys

A Message(BenQ Hotkey Manager) will be show when the hot key is activated (as noted in
the below table), to indicate to the user that the selected action has been performed.

Legacy Devices and Standards
Flash Update

The BIOS provide diskette-based BIOS update utility, include Boot Block with Crisis detect
and recovery. The BIOS update utility must be executed from the diskette. When booting to
the diskette, the BIOS update utility must automatically execute.
The BIOS update utility must contain an identification mechanism that will identify the
correct machine for which it is intended and execute only on that machine. The BIOS
update utility must not execute on any other machine.

 The utility need to check model ID to decide to update BIOS or not.

 The utility can run under Windows 2000 and Windows XP.

Additional BIOS Requirement

CMOS/ECMOS Map: The BIOS supply a document that contains definitions for all of the
CMOS/ECMOS addresses that are used by the BIOS. The BIOS also supply a list of
default values for the CMOS/ECMOS variables.

EEPROM programming tool

For use in service centers, UUID and MAC address programming tools should be provided.

3.3 ME requirement

(The detail decription should follow ME document and focus on the marketing spec.)

DHS52 should follow ME “BenQ appearance specification”,”BenQ accoustic test plan”
and “BenQ ME test plan” document
