This article will be talking about resetting the BIOS. The BIOS resetting could be used in situations like resetting the manually set password protection or the changes that may prevent the user to access the BIOS.

What is BIOS?

The BIOS is the software stored on the memory chip on the motherboard. It instructs the computer on how to perform a number of basic functions such as booting and keyboard control. Alternatively referred to as a RTC (real-time clock), NVRAM (non-volatile RAM) or CMOS RAM.

Target Device:

We will be using the VDX2-6554 to be the target device in this section.

The methods that could used for BIOS reset are:

Press F9 in the BIOS to load the default setting
Pressing the End key on the keyboard while booting up the board (Based on ICOP's VSX and VDX series board)
Discharging the CMOS battery

The steps to reset the BIOS

The wrong settings of the BIOS may cause abnormal behavior on the board, and resetting the BIOS sometimes could easily resolve the problem
Use a conductor like a wire to connect the onboard battery Positive and Negative for 3 seconds (The picture shows the VDX2-6554 contact point)
The CMOS memory power supply is down, and the stored data are lost
Enter to the BIOS to check the default will be Factory setting

Main features of VDX2-6554:

DM&P SoC Vortex86DX2- 800Hz
512MB / 1GB DDR2 onboard
4S / 2U / VGA / LCD / LVDS / LAN / LPT / SPI / Audio / 16GPIO / SATA
Operation Temperature: -20 ~ +70°C / -40 ~ +85°C (Optional)
