Acer Travelmate 740 Service Guide

							Chapter 233
The following table describes the parameters in this screen.  Settings in boldface are the default and 
suggested parameter settings
.
Setting the Boot Drive Sequence
The Boot Drive Sequence section lists boot priorities (1st, 2nd, 3rd and 4rd ) for bootable drives in your 
computer.
For example, the default value (1st:  Floppy Disk, 2nd:  CD-ROM, 3rd:  Hard Disk) tells the computer to first 
search for a bootable floppy disk in the floppy drive.  If it finds one present, it boots up from that floppy disk.  If 
not, the computer continues to search for a bootable CD-ROM in the CD-ROM drive.  If it cannot boot up from 
the CD-ROM drive, it continues by booting up from the hard disk.  
To set the boot drive sequence, use the 
w / y keys to select a priority level (1st, 2nd, 3rd and 4rd), then use 
the 
z / x keys to select the device for that priority level.
ParameterDescriptionOptions

When set to 
Auto, the computer automatically 
determines the display device when the computer 
starts up.  If an external display device (e.g., monitor)

Setting a Password
Follow these steps: 
1.
Use the cursor up/down keys to highlight a Password parameter (Setup, Power-on or Hard Disk) and 
press the 
z / x key.  The password box appears:
2.
Type a password.  The password may consist of up to eight characters (A-Z, a-z, 0-9). 
IMPORTANT:
Be very careful when typing your password because the characters do not appear on the 
screen. 
3.
Press 
e.  Retype the password to verify your first entry and press e.
4.
After setting the password, the computer automatically sets the chosen password parameter to Present.
Three password types protect your computer from unauthorized access.  Setting these passwords creates 
several different levels of protection for your computer and data:
!Setup Password prevents unauthorized entry to the BIOS Utility.  Once set, you must key-in this 
password to gain access to the BIOS Utility.  
!Power-On Password secures your computer against unauthorized use.  Combine the use of this 
password with password checkpoints on boot-up and resume from hibernation for maximum 
security.
!Hard Disk Password protects your data by preventing unauthorized access to your hard disk.  
Even if the hard disk is removed from the computer and moved to another computer, it cannot be 
accessed without the Hard Disk Password.
When a password is set, a password prompt appears on the left-hand corner of the display screen.
1.
When the Setup Password is set, the following prompt appears when you press 
m to enter the BIOS 
Utility at boot-up.
Type the Setup Password and press 
e to access the BIOS Utility.
2.
When the Power-on Password is set, the following prompt appears at boot-up.
Type the Power-on Password (a symbol appears for each character you type) and press 
e to use the 
computer.  If you enter the password incorrectly, an x
 symbol appears.  Try again and press 
e.
3.
When the Hard Disk Password is set, the following prompt appears at boot-up.
Type the Hard Disk Password (a symbol appears for each character you type) and press 
e to use the 
computer.   If you enter the password incorrectly, an x
 symbol appears.  Try again and press 
e.

HDD Password 
						

							Chapter 237
You have three chances to enter a password.  If you successfully entered the password, the system starts 
Windows.
If you fail to enter the password correctly after three tries, the system hangs.
To change a password, follow the same steps used to set a password.
To remove a password, follow the same steps used to set a password, except type nothing in the password 
boxes.

If you want to restore all parameter settings to their default values, select this menu item and press e.  The 
following dialog box displays.
If you would like to load default settings for all parameters, use the cursor 
z / x keys to select Yes
; then press 
e.  Choose No
 if otherwise.
