After the module reboot, the optimal (factory default) BIOS Setup settings can be loaded. If
necessary, enter the BIOS Setup, change the necessary parameters, save and exit (paragraph 5.7
Exit).
3. Run the main BIOS update program from the VXDXBIOS folder. You will need to specify the file
name of the BIOS image for updating as the parameter:
C:\VXDXBIOS\vxdxbios.exe c307v311.bin
If the update is successful the program will show the following messages:
Load file C:\VXDXBIOS\c307v311.bin...
START FLASH ERASE
FLASH ERASE OK. ERASE TIME 4.62 S
FLASH WRITE OK
FLASH VERIFY OK
AM29F040B loaded successfully.
6. After updating the main BIOS copy you need to restart the module. To do so, just power off and
then power on the module, or press the SW1 reset key, or reset the module via the opto-isolated
reset signal. In addition you can remove the XP21 jumper to prevent switching to the BIOS backup.
After the module reboot, the optimal (factory default) BIOS Setup settings can be loaded. If
necessary, enter the BIOS Setup, change the necessary parameters, save and exit (paragraph 5.7
Exit).
7. Make sure the module is booted from the main BIOS copy:
a. The jumper XP21 is installed while the XP26 jumper is removed. When booting up, the WDT2
watchdog timer must not be activated (paragraph
4.3.15.2 WDT2 watchdog timer
). Make sure
that WDT2 has not been triggered, which can be verified by the LED connected to the XP3
connector (paragraph
4.3.21 LED indication
). You can also check the date and version of the
BIOS when going through the POST procedure and in the BIOS Setup menu (Section
5 Basic
Input/Output System (BIOS)
).
b. XP21 jumper is removed or both XP21 and XP26 jumpers are installed at the same time. The
module always boots from the master copy only. If the module boots, the upgrade is successful.
If the module boots from the main BIOS copy, the upgrade was successful.
If the BIOS backup copy is damaged and the module fails to boot from the backup copy or if the
WDT2 watchdog timer occasionally triggers (the XP21 jumper is installed), in this case to restore
the BIOS backup copy the module must be sent for repairs
with indication of the reason “BIOS
backup copy is damaged
”.

The main BIOS copy is stored in the FLASH memory integrated into Vortex86DX SoC and
connected to the SPI interface.
When updating the BIOS using the integrated console I/O (par.

(Configuration of Console I/O settings), note that after updating the image and
reboot the optimal (factory) BIOS Setup settings will be loaded. If the module is rebooted from the
