A guidance how to create a bootable USB-Stick / Pendrive (incl. MS-DOS system files) to perform a BIOS update.
The following tools are needed:
Instruction to create a bootable USB-Stick
Starting the BIOS-Update from USB-Stick
First, go into your BIOS-Setup and change the Bootsequence to USB-Stick/Drive (search for an option like Bootsequence, First Boot Device, or something similarly).
Insert the USB-Stick and restart your PC. If all went well - MS-DOS starts and you can see the famous DOS-Prompt (C:\>).
Now you can start the BIOS update. Remember: it's a good idea to backup the old BIOS version.

I would guess that you have to copy all of them on to the pendrive. Boot the pendrive and insert the command: flash.bat at the DOS prompt.

This error msg could mean that your BIOS-Chip is defective.
Did everything you did and ran the command to flash it and I got the errror Error - Problem getting flash information ( I even tried disabling Boot Block Protection in the BIOS and have gone through the BIOS and found no other write protection settings, and there is no Pin on the motherboard related to WP)Chris1337c 18.Feb.2014 18:09
