Software Specification 6 Chapter Software Specifications Get to know more about the Eee PC 4G (701) Notebook with a detailed look at the software specifications. T he information contained in the chapter can be quite useful when you are troubleshooting the system’s hardware. Each item has its individual usage for you to Understand the software side of the notebook’s architecture.
Software Specification 1. General Description The specification is a guideline for BIOS development on 701 platforms. Anyone who needed the system BIOS information can check this document for reference. The general device specification, hardware block diagram, SMBUS, GPIO definition and so on are subjected to be depicted in this document. Hotkeys implementation and other BIOS features are also included in the document.

Software Specification 4. Specified Function Tables The Specified Functions are controlled via General Purpose Pins of Chipsets, following tables are the definition of The Functions which controlled via the GPIO pins of South-Bridge (ICH6M). Table 4-1.
Software Specification 5. Setup Menu 701 system BIOS allows users to change some system hardware/function settings during POST (power on self test) stage, users may hit F2 key to enter SETUP mode in POST, the setup feature is categorized into 4 menus described as below. 5.1 Main Menu Main menu describes system overall information with some user changeable setting, it contains below items. 1. 2. 3. 4. 5. 6. System Firmware: Current version for the system, EC and VGA BIOS.
Software Specification 5.2 Advanced Menu In advanced menu the users may configure IDE configuration, onboard devices and OS to install type settings may be changed as well. Detailed settings are described below. 1. IDE configuration: See 5.2.1 2. Onboard Devices Configuration: See 5.2.2 3.
Software Specification 5.2.1 IDE Configuration 1. 2. IDE Master: See details. IDE Slave: See details.
Software Specification 5.2.2 Onboard Devices Configuration: 1. 2. 3. 4. 5. 6. 7. 8.
Software Specification 5.3 Security Menu 701 BIOS supports three kinds of password for security protection: 1. Supervisor Password: Users may set, change or erase system password, the password data is saved in non-volatile device (CMOS), system password check is done during POST(Power On Self Test). The BIOS will prompt a dialog message to ask user for password check when: The system has password stored, and “Password on boot” setting in BIOS SETUP is enabled.
Software Specification 5.4 Boot Menu In this menu users can decide the boot sequence, as long as the device with highest boot priority exists, system BIOS will boot from it, device boot priority is adjusted by pressing “+”,”-“ or space key on the selected (highlighted) item. 3 bootable devices fare listed in this menu (BIOS default boot sequence). 1. Boot Device Priority: See 5.6.1 2. Boot Settings Configuration: See 5.6.2 3.
Software Specification 5.4.1 Boot Device Priority In this menu specifies the boot sequence from the available devices. User can change boot devices priority.
Software Specification 5.4.2 Boot Settings Configuration 1. Quick Boot: [Enabled] decrease time when boot. 2. Quiet Boot: [Disable]: Display normal POST messages. [Enable]: Displays OEM Logo instead of POST messages.
Software Specification 5.5 Exit Menu In Exit BIOS setup, users may make final decision if they want to save the change just made or load BIOS default setting. 1 2 3 4 Exit & Save Changes: Exit system setup after saving the changes. Exit & Discard Changes: Exit system setup without saving any changes. Discard Changes: Discards changes done so far to any of the setup questions. Load setup Defaults: Load Optimal Default values for all the setup questions.
Software Specification 6. Device resources 701 uses ICH6M chipset as its power management core logic, the chipset supports most features the ACPI 2.0 interface specifies, for ACPI 2.0 compliant OS. The BIOS has below features implemented: (1). System sleep states: The system supports: (a). S0 state: The CPU and all devices are working. (b). S3 state: system is in low power state, with all setting saved into RAM. Most of the devices are power off (c).
Software Specification 7 Embedded Controller (EC) 7.1 Hot Key Table 8.1.
Software Specification 8. Thermal Policy There is only one CPU fan in this project. The controlling method is to plan several step thermal ranges then every range mapping to different fan speed. The following table is thermal policy table and Fan Curve.
