E-26 8580/8590 Vehicle-Mount Computer User Manual
In order to make a BIOS recovery from a USB device (floppy, USB Stick) the BIOS
file must be copied into the root directory of the storage device and renamed to
AMIBOOT.ROM. Then boot from the device.
The BIOS issues a series of 4 beeps that indicate that the system BIOS ROM file has
successfully been updated.
After that the system will automatically reset and reboot.
Important: If the boot block of the BIOS is corrupted the recovery scenario as
described here will not be possible. In this situation the unit needs
to be sent in for repair.
E.11 BIOS Security Features
The BIOS provides both a supervisor and user password. If you use both passwords,
the supervisor password must be set first. The system can be configured so that all
users must enter a password every time the system boots or when setup is executed.
The two passwords activate two different levels of security. If you select password
support you are prompted for a one to six character password. Type the password on
the keyboard. The password does not appear on the screen when typed.
The supervisor password (supervisor mode) gives unrestricted access to view and
change all the setup options. The user password (user mode) gives restricted access
to view and change setup options.
If only the supervisor password is set, pressing [ENTER] at the password prompt of
the BIOS setup program allows the user restricted access to setup.
Setting the password check to ‘Always’ restricts who can boot the system. The
password prompt will be displayed before the system attempts to load the operating
system. If only the supervisor password is set, pressing [ENTER] at the password
prompt allows the user to boot the system.
E.12 Hard Disk Security Features
Hard disk security uses the security mode feature commands defined in the ATA
specification. This functionality allows users to protect data using drive-level
passwords. The passwords are kept within the drive, so data is protected even if the
drive is moved to another computer system.
