    Each SmmDriver entry point used in 80_PORT
    * If the BIOS detects error 2C, 2E, or 30 (base 512K RAM error), it displays an additional word-bitmap (xxxx) 
    indicating the address line or bits that failed. For example, 2C 0002 means address line 1 (bit one set) has 
    failed. 2E 1020 means data bits 12 and 5 (bits 12 and 5 set) have failed in the lower 16 bits. Note that error 30 
    cannot occur on 386SX systems because they have a 16 rather than 32-bit bus. The BIOS also sends the 
    bitmap to the port-80 LED display. It first displays the check point code, followed by a delay, the high-order 
    byte, another delay, and then the low-order byte of the error. It repeats this sequence continuously.

    Clearing Password Check and BIOS Recovery
    This section provides you with the standard operating procedures of clearing password and BIOS recovery for 
    eMachine HM70-MV. The machine provides one Hardware Open Gap on main board for clearing password 
    check, and one Hotkey for enabling BIOS Recovery.
    Clearing Password Check
    Steps for Clearing BIOS Password Check
    If users set BIOS Password (Supervisor Password and/or User Password) for a security reason, BIOS will ask 
    the password during systems POST or when systems enter to BIOS Setup menu. However, once it is 
    necessary to bypass the password check, users need to short the HW Gap to clear the password by the 
    following steps:
    1.Power Off the system, and remove HDD, AC and Battery from the machine.
    2.Disconnect the RTC Battery cable and locate the J1 jumper.
    3.Use an electric conductivity tool to short the two points of the HW Gap.
    4.Plug in AC, keep the short condition on the HW Gap, and press Power Button to power on the system till 
    BIOS POST finish. Then remove the tool from the HW Gap.
    5.Restart system. Press F2 key to enter BIOS Setup menu.
    6.If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and try 
    again.
    NOTE: These steps are only for clearing BIOS Password (Supervisor Password and User Password).

    BIOS Recovery by Crisis Disk
    BIOS Recovery Boot Block:
    BIOS Recovery Boot Block is a special block of BIOS. It is used to boot up the system with minimum BIOS 
    initialization. Users can enable this feature to restore the BIOS firmware to a successful one once the previous 
    BIOS flashing process failed.
    BIOS Recovery Hotkey:
    The system provides a function hotkey: Fn+Esc, for enable BIOS Recovery process when system is powered 
    on during BIOS POST. To use this function, it is strongly recommended to have the AC adapter and Battery 
    present. If this function is enabled, the system will force the BIOS to enter a special BIOS block, called Boot 
    Block.
    Steps for BIOS Recovery from USB Storage:
    Before doing this, prepare the Crisis USB key. The Crisis USB key could be made by executing the Crisis Disk 
    program in another system with Windows XP OS.
    Follow the steps below:
    1.Format the USB storage disk using the Fast Format option. 
    2.Save ROM file (file name: JAL90x64.fd) to the root directory of USB storage. Make sure that there is no 
    other BIOS file saved in the same directory.
    3.Plug USB storage into USB port.
    4.Press Fn + ESC button then plug in AC power.
    The Power button flashes once.
    5.Press Power button to initiate system CRISIS mode.
    When CRISIS is complete, the system auto restarts with a workable BIOS. 
    6.Update the latest version BIOS for this machine by regular BIOS flashing process.
