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.

Older Instructions pertaining to some Older files

You need three files msdos.sys command.com and io.sys to boot into a dos environment.
To Format the USB Stick , I used to the HP Utility called HP USB Disk Storage Format Tool . Run the HP utility with the location of these 3 files and you are done.
Once the formatting is done copy the utility to flash your rom and the image to flash it with on to the USB stick.
On LV678 the BIOS saw USB stick as a hard drive and I raised its priority ahead of the SATA disk and the machine booted into the DOS environment.
