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. System Firmware: Current version for the system, EC and VGA BIOS.
2. Type: Show the installed CPU Brand String.
3. Count: Show the CPU core number.
4. Installed Size: Total system available memory.
5. System Time: Current time
6. System Date: Current date.

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.
If password verification fails for 3 times, the system BIOS will halt the machine to inhibit users
from operating.
User can modify all setup item if user use Supervisor password to enter setup.
2. User Password: If your setting of BIOS have been modified by other, You can setting the
function [Enable], and Key in your password and confirm, Don't modify BIOS setting if no
password.
User is just able to modify some of setup item if user use user password to enter setup

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. Onboard LAN Boot ROM: Boot from LAN

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 Exit & Save Changes: Exit system setup after saving the changes.
2 Exit & Discard Changes: Exit system setup without saving any changes.
3 Discard Changes: Discards changes done so far to any of the setup questions.
4 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). S4 state: The system is powered off, with all settings saved into hard disk.
(d). S5 states. Mechanical off.
