New versions of system programsNew features or options

Restore a BIOS when it becomes corrupted.

Use the Flash utility to update the system BIOS Flash ROM.


If a Crisis Recovery Disc is not available, create one before BIOS Flash utility is used. See


Do not install memory related drivers (XMS, EMS, DPMI) when BIOS Flash is used.


Use AC adaptor power supply when running BIOS Flash utility. If battery pack does not contain power to finish loading BIOS Flash, do not boot system.

Perform the following to run BIOS Flash update:

1.Prepare a bootable USB HDD.

2.Copy Flash utilities to bootable USB HDD.

3.Boot system from bootable USB HDD.


BIOS Flash utility has auto execution function.

HDD/BIOS Password Utilities


If Power-onPassword authentication is enabled, the BIOS password can only be cleared by initiating the Crisis Disk Recovery procedure. SeeChapter 5, BIOS Recovery by Crisis Disk.

Removing HDD Passwords

This section provides details about removing an HDD password from the BIOS. If the HDD password is incorrectly entered three times, an error is generated. (Figure 2-20)

Figure 2-20.Password Error Status

To reset the HDD password, perform the following:

1. Press Enter to continue. TheSelect Item dialog is shown.(Figure 2-21)

Figure 2-21.Select Item

2.Use the and keys to highlight Enter Unlock Password and pressEnter. TheEnter Unlock Password dialog is shown.(Figure 2-22)

System Utilities



A key code is generated for use with unlocking utility. Make note of this code.

3.On a separate, compatible device, boot to DOS.

4.Execute UnlockHD.exe (Figure 2-23) to create a password unlock code. Use the format <UnlockHD [key code]> with the code noted in theFigure 2-22.

Example: UnlockHD 54591747

The command generates a password which can be used for unlocking the HDD.

Password: 41499389

Clearing BIOS Passwords

If a BIOS password (Supervisor Password and/or User Password) is set, the BIOS will prompt for the password at system POST or upon entering the BIOS setup menu. Clear the password check with the following procedure:

1. Remove HDD, AC adapter and Battery.

2. Remove power from system.

3. Disconnect RTC Battery.

4. Locate the RTC_RST point (A). (Figure 2-24)

6. Plug in AC adapter.

7. Press Power button until BIOS POST is finished 8. Remove conductivity tool from RCT_RST point.

9. Restart the system and press F2 to enterBIOS Utility Setup menu. 10. If no password prompt is shown, BIOS password is cleared.

11. If password prompt is shown, repeat steps 1 through 9.

Using Boot Sequence Selector

The Boot Sequence Selector allows the boot order to be changed without accessing the BIOS. To use theBoot Sequence Selector, perform the following steps:

1.Boot to DOS.

2.Enter bs <#>,bs.exe followed by a digit from 1 to 4, at the command prompt to select a boot sequence.


*** Boot Sequence Selector Version 0.03 ***

Created by Rockwell Chuang 10/01/2005.1. Usage:

BS [ 1 | 2 | 3 | 4 ]

BS 1: [Floppy] => [HardDisk] => [CD-ROM]=> [LAN] BS 2: [HardDisk] =>[CD-ROM]=> [LAN] => [Floppy] BS 3:[CD-ROM]=> [HardDisk] => [LAN] => [Floppy] BS 4: [LAN] => [Floppy] => [HardDisk] =>[CD-ROM]


Figure 2-27.Boot Sequence Selector


Enter bs <2> at the command prompt to change the boot sequence to HDD | CD ROM | LAN | Floppy.

Using DMITools

The DMI (Desktop Management Interface)Tool copies BIOS information to EEPROM. Used in the DMI pool for hardware management.

When the BIOS shows Verifying DMI pool data, it is checking that the table correlates with the hardware before sending it to the operating system (Windows, etc.).

To update the DMI Pool, perform the following:

1.Boot to DOS.

2.At the prompt, enter dmitools with one of the following arguments:

/r ==> Read dmi information from memory

/wm ==> Write Manufacturer Name to EEPROM (max. 16 characters)/wp ==> Write Product Name to EEPROM (max. 16 characters)
