System parameters can be modified by going into
BIOS
Setup menu, this menu allows you to configure the system parameters and
save the configuration into the 128 bytes CMOS area, (normally in the RTC chip or in the main chipset).
The AwardBIOS™ that installed in the
Flash ROM
of the motherboard is a custom version of an industry standard BIOS. The BIOS
provides critical low-level support for standard devices such as hard disk drives, serial and parallel ports.
Most BIOS setting of AX4LR / AX4LR-N had been optimized by AOpen’s R&D engineering team. But, the default setting of BIOS
still can’t fine-tune the chipset controlling entire system. Hence, the rest of this chapter is intended to guide you through the
process of configuring your system using setup.
Currently there are two kinds of beep sound when system fails to boot at POST. The first type of beep sound consists of a single
long beep and two short beeps, indicating a video error has failed BIOS from initializing video screen for displaying any additional
information. The 2
nd
type of beep sound is a single long beep that beeping repeatedly, signaling a DRAM error has occurred. You
may look over the indicated error according to different beep significances.
To enter to BIOS setup menu
, press <Del> when
POST (Power-On Self Test)
screen is shown on your monitor.
Note:
Because the BIOS code is the most often
changed part of the motherboard design, the BIOS
information contained in this manual may be
different with actual BIOS that come with your
motherboard.
