Supported Industry Standards Butterfly 2.0 is the platform that designed utilizes AMD 690E+ SB600 chipsets. The BIOS will operate primarily in ACPI mode, and it doesn’t support conventional Advanced Power Management (APM). The following standards have been determined to provide definite benefits to the end user.

System Management BIOS (SMBIOS) The BIOS must support the SMBIOS Specification version 2.5 (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. Note SMBIOS must provide 32-bit entry table 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.

1.5GHZ DDR2-1G1 CF1G LINUX BenQ provides a two-level password security scheme stored in CMOS.

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.

Serial Number (S/N) 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: 99K0502T0131500001DHR470.

Model ID String (for SLP) On BenQ System, it has a specific text string embedded in Memory F000:FFB0h. It will be identified the model and BIOS version by diagnostic program and flash utility. The format is as below:

The logo should be displayed on the screen during POST. It is a color bitmap (1366*768*24bits 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 F9 key for Multi Boot Menu during POST. The POST progress bar

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 “F9” to select the boot device. The list of possible boot devices sequence will include:

Primary Hard Drive (built-in)

CD-ROM/DVD-ROM Drive

Removable Device

Network (PXE) for built-in LAN

Boot From LAN The system 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’ design.

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.

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.

BIOS Setup Utility BIOS is required to provide the ROM-base setup program. During Post, users enter to the setup mode via pressing “F2”, “F9” for Multi Boot Menu, and “F12” for Boot from LAN. During setup, all Fn function keys and power saving functions are disabled. No beep sound is needed

Linpus Preload Solution

-Linpus Preload solution is not a product only, which also provides the on-site

service. The maximum value of this project is that it reduces the cost of vendor. We

will designate a "tiger team" to handle beta and early production calls from

customers from our Support group. Sign-off on customer and internal training

materials will be done by Project Manager.

-Linpus would provide on-site support should any software related issues are raised

during testing and pre-loading phases on production line.

-Linpus offers Linpus Preload Solution as an option to facilitate a both efficient

and cost effective way pre-loading software on production line.

-Multicast supported in our preload, clients can join in the multicast group at any moment in the product line. We call this “Join in Time”. All servers used in the project are Linux server, they have the lowest of requirements of hardware and even we can use the notebooks directly as the server.
