AUTO-DETECT
H
ARD DISKS
The Auto-Detect Hard Disks option allows you to have AMIBIOS automatically detect
the type of hard disk drive(s) in your system. The automatic detection functions only if
you have IDE drives. The parameters are reported on the Standard CMOS Setup screen.
AMIBIOS searches first for the primary master and slave hard disk drives, then for the
secondary master and slave drives. If it can access a drive, it reads the disk parameters.
It then searches the AMIBIOS drive type table for matching parameters to determine the
disk type and displays both the type and parameters on the screen. If no matching
parameters are found in the table, AMIBIOS specifies the type as "User" and fills in the
parameter values it found on the drive. If it cannot access the drive or if it is not an IDE
drive, AMIBIOS times out and specifies that the disk drive is "Not Installed."
_______________________________________________________________________
NOTE: The auto detect feature displays disk parameter values as established by the
drive manufacturer. If the drive has been formatted using any other values, accepting the
auto detect values will cause erratic behavior. You must either reformat the drive to meet
the manufacturer's specifications or use Standard CMOS Setup to enter parameters which
match the current format of the drive.
_______________________________________________________________________
If you do not want to accept the hard disk type and its associated parameters as reported
by AMIBIOS or if the drive is "Not Installed," you may use Standard CMOS Setup to set
up the correct parameters for the drive.
Once the parameters are correct for all of the drives, you may exit from the Standard
CMOS Setup screen and save the settings in the CMOS.

ASSWORD
AMIBIOS Setup has an optional password feature which can be configured so that a
password must be entered each time the system boots or just when a user attempts to
enter AMIBIOS Setup. (See the Advanced CMOS Setup section of this manual for infor-
mation on how to enable the Password Check option.)
The Change Supervisor Password and Change User Password options on the
AMIBIOS Setup Main Menu allow you to establish passwords, change the current
passwords or disable the password prompts by entering null passwords. The passwords
are stored in CMOS RAM.
The Change User Password function is accessible only if the supervisor password has
been established previously. If you have signed on under the user password, you cannot
change the supervisor password.
_______________________________________________________________________
NOTE: The null password is the system default and is in effect if a password has not
been assigned or if the CMOS has been corrupted. In this case, the "Enter CURRENT
Password" prompt is bypassed when you boot the system, and you must establish a new
password.
