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
         User is just able to modify some of setup item if user use user password to enter setup

                                                                       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. Onboard LAN Boot ROM: Boot from LAN

                                                                     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

         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   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
   (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.
