Hello, maybe someone here knows how to flash the Bios HighPoint Rocket 640L correctly. I get a little confused. How must the command line be written correctly so that the controller is bootable again.
I have the following to choose from. I have a clean DOS boot floppy.

load.exe Flash utility for DOS
rr640l.v15 BIOS image file for RR640L
640lload.100 Autoloader for RR640L


3. Updating BIOS
====================
The flash utility (load.exe) is used to update controller BIOS.
load.exe must run under pure DOS environment. It cannot run in a DOS box
on Windows system. You should boot from a DOS floppy without any device
drivers.

The following command line is used to launch the flash utility:

load.exe [options] [filename]

Command line options:

/A Update Autoload.

/Q Silent mode. The program will not prompt for you to
confirm the flashing process.

/V Verbose mode. The program will show more detailed
information about the flashing process.

/S <bus> Only search adapters on specified PCI bus. <bus>
specifies the PCI bus number (a value from 0 to 255).

/D <device> Only search adapters for specified PCI device number.
<device> specifies the PCI device number (a value from
0 to 31).

/C Configure BIOS parameters before updating.

I hope there is anybody how can tell me the right way.
Thanks
