6. BIOS
Aurora’s BIOS provides access to many valuable features. These instructions show how to enter the BIOS, set up
features, and restore the BIOS to its default settings.
6.1 Entering the BIOS
The BIOS may be entered during startup by pressing the
DEL
key on an attached keyboard or pressing
F4
if
using console redirection. Press the key repeatedly right after power-on or reset until the BIOS screen appears.
After a certain amount of time during startup, the BIOS will ignore the DEL or F4 key. If you wait too long and the
system does not respond, simply reset the system (or power down) and try again.
6.2 Restoring Default BIOS Settings
In order to load the default BIOS settings, turn off the system and install a jumper on pins 2-3 of jumper block
JBAT1, located on the bottom right corner of the board. This will clear CMOS and reset the BIOS to the default
settings. After three seconds put the jumper back to position 1-2 and turn the system on.
On the first screen after booting up, the user will be asked to press
F1
to run SETUP, or
F2
to load the defaults.
6.3 Setting the Date and Time
The date and time are set in the BIOS. Select
Main
menu, then enter the date and time at the bottom of the
screen. This screen also displays the CPU speed and memory capacity of the board.
6.4 ISA Bus IRQ Reservation
An ISA bus IRQ must be reserved in the BIOS in order to be used by the on-board ISA bus circuits or an installed
PC/104 module. To reserve an IRQ, go to the
PCIPnP
menu and scroll down to the IRQ list at the bottom. The
default settings are IRQ15 reserved with the remaining IRQs available.
6.5 Boot Priority
To select Boot devices and set their priority, go to the
Boot
->
Boot device priority
menu and select the first boot
device from the list.
Upon clicking on the first boot device, a window with the available devices will open. The user can select any of
the devices as the first boot device.
The devices can be a SATA HDD, a network drive, or a USB device.
The USB device present in this list is the first Drive defined in the “USB Drives” Menu.
Here are the steps to select a USB drive to boot from:
1. Boot-> USB Drives -> 1
st
Drive -> ( select a USB device from the list)
2. Boot->Boot Device Priority-> 1
st
Boot device ( select the USB device which has been defines in line 1)
In this way, the system will try to boot from the USB device. The same procedure applies for other boot devices
(2nd, 3rd,…).
6.6 Chipset
The chipset menu is provided to define and change the North / South Bridge options such as Graphic Adapter
Modes, flat panel type (default is 800x600), and enable/disable on-board PCI3 line and Ethernet adapter.
By default, both PCIe and LAN controllers are enabled. This can be changed in the South Bridge menu.
