Here are the dos instructions from the machines website:
Run the BIOS update utility from DOS environment (Non-Windows users)
NOTE: You will need to provide a bootable DOS diskette. This executable file does not create the DOS system files.
Copy the file D830_A11.EXE to a bootable floppy.
Boot from the floppy to the DOS prompt.
Run the file by typing Y:\D830_A11.EXE (where y is the drive letter where the executable is located).
You will have to go into the bios and set first boot device for floppy if you have one, if not, then usb device.
