Bios Flashing Instructions

Make A USB Flash disk.

Building a flash drive to update bios on LV motherboards

How to build the USB boot stick:

You will need:

  1. Bios Image (Board Specfic)
  2. Rufus Utility, downloadable here

NOTE: The tools and bios files for the LV-67X line are located on the archive(Windows share: \\archive2\pub\Archive\PC\Bios)

To Create the USB Flash Disk:

  1. Run the Rufus utility
  2. Choose options to make the usbflash disk freedos bootable
  3. Once complete remount the flash disk and copy the folders containing the update utilities for the motherboards you need to update

This disk should now be capable of Flashing your bios.

In the LV-67B bios (and I suspect others in the LV line), the flash disk can be put into 1 of 3 modes USB-FDD, USB-HDD, AUTO. The Auto mode guesses either FDD or HDD. When in the FDD mode the bios treats the flash disk like a floppy. This mode DOES NOT work with the tools for building a USB flash Drive. The HDD mode does work. To use this mode however, you need to specify Hard disk as the booting device and the modify the Hard drive boot order to put your USB Flash disk first.


======= Bios Setup =======

  • Go to tab Exit
    • Load Default settings
    • Then enable the following options
  • Main
    • Boot Features
      • enable quickboot
      • enable console redirection
        • ensure rate is 115200
  • Advanced
    • network config
      • enable lan oprom
  • Others
    • hardware monitor
      • warning temp = 80c
      • enable cpu fan temp control
        • temp = 40c
        • threshold = 5c
  • Boot (use + and - to move items, arrow keys to navigate. shift+1 toggles enabled state)
    1. usb hdd
    2. pci LAN (will not show both NICs until reboot after lan oprom enabled)
    3. HDD0
    4. internal shell (if first boots fail, has options to retry, go into bios, etc.)
    5. move all others below these, and disable with shift+1

======= Troubleshooting =======

  • Step 1 is to reset bios to default settings and reset options as above.
  • If this fails, remove power from the motherboard, move the cmos jumper to position 2, wait at least 30 seconds, and then move it back. Then reset bios options as above.
    • Jumper: JRTC
    • Type: Onboard 3-pin jumper
JRTC Mode
1-2 Clear CMOS
2-3 Normal Operation
Default setting: 2-3
