Hard disk 0, Hard disk 1
This parameter specifies the type of fixed disk drive(s) installed in or connected to your system. Hard disk 0 is the
parameter that denotes the first (or only) fixed disk drive of your system, and Hard disk 1 is the parameter that
denotes the second, if one exists, fixed disk drive of your system.
The identity lever, located on the front panel of your system, specifies the type of pre-installed fixed disk drive
delivered with your system.
To change the type of the fixed disk drive, move the cursor to Hard disk 0 and press ENTER. A window menu
lists the available types described below.
None or non-IDE
No fixed disk is installed or if an option board BIOS should be used to control the fixed disk.
Auto IDE/AT
IDE/AT-type disk is installed. Disk parameters are automatically retrieved. This option must be used with hard
disks larger than 528MB.
User defined IDE/AT
You want to manually define the parameters for IDE/AT or ST506 fixed disk drive(s). This option can not be
used with hard disks larger than 528MB.
If you have both IDE/AT and SCSI fixed disk drives connected to your system, configure the IDE/AT disk drive as
Hard disk 0.
Local bus IDE
Use this parameter to enable or disable the local bus IDE interface on your system board. When Enabled, the
BIOS determines the ANSI mode supported by the attached fixed disks and sets transfer speed according to the
highest mode (0 to 4) supported. It is recommended that this parameter value remain Enabled unless you install
a SCSI expansion board.
Parallel port
This parameter controls the functionality of the parallel port on the system board. Press ENTER on the parameter
and a sub menu, similar to the one below, appears:
Base I/O address
Set the base address for the parallel port. Auto, the recommended value for this sub parameter, allows
the system to check the port determination scheme upon power-on. Selecting Disabled deactivates the
parallel port on the system board, while selecting 378H or 278H configures the parallel port to the
respective addresses.
Interrupt level
Set the Interrupt level for the parallel port. Auto, the recommended value for this sub parameter, allows
the Interrupt level value to correspond with the levels selected for the Base I/O address and other
channels. If 378H is selected for the Base I/O address, the Interrupt level will be set to IRQ 7 and if 278H
is selected for the Base I/O address, the Interrupt level will be set to IRQ 5.
DMA channel
