As you scroll through the disk types, the drive Type displays, along with values for size, cylinders,
heads, write precompensation and sectors. Available predefined hard disk drive types are listed at
the end of this section. If the parameters supplied by the manufacturer of your disk drive do not
match any of these preprogrammed drive types, you may have AMIBIOS detect the drive type
automatically (if it is an IDE drive), or you may select the User drive type to enter the parameters
manually as described below.
Set the drive type to CD-ROM to boot from a CD-ROM drive.
Not Installed is available for use as an option. This option can be used for diskless work stations.
Automatic Detection of Drive Type
If any of the hard disks are IDE drives, AMIBIOS can automatically configure the drive type by
detecting the IDE drive parameters and reporting them on the Standard CMOS Setup screen.
You may invoke automatic detection of IDE drives in one of three ways:
• Press Enter when the cursor is in the Type field. AMIBIOS detects the drive type and parameters
as requested. If the drive type is not defined in the drive type table, this option displays User
as the drive type and displays the parameters which were detected by AMIBIOS. The detected
drive type values may then be saved in the CMOS.
• Set the drive type to Auto to have AMIBIOS detect the drive type and parameters automatically
each time the system is booted up. This option does not display the drive type on the Standard
CMOS Setup screen, but does display it on the System Configuration screen shown after a
successful bootup.
• Select the Auto-Detect Hard Disks option on the AMIBIOS Setup Main Menu to have AMIBIOS
automatically detect the type and parameters of each hard drive and place the information into
the Standard CMOS Setup screen. The detected drive type values may then be saved in the
CMOS. This option is described in the Running AMIBIOS Setup section of the System BIOS
chapter of this manual.
Note: The auto detect feature displays disk parameter values as established by the drive manufac-
turer. 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 the User type to enter parameters which match the
current format of the drive.
User-Defined Drive Types
If the parameters supplied by the manufacturer of your disk drive do not match any of the
preprogrammed drive types in the Hard Disk Drive Types table at the end of this section, you may
enter the parameters manually.
The user-defined parameters for each of the four drives may be different, which effectively allows
four different user-definable hard disk types.
Scroll to the end of the drive type list to the User type. You can manually enter the Cyln, Head,
WPcom and Sec parameters. The Size parameter is automatically calculated and displayed by the
system based on the other parameters entered.
