SD-flasher.exe under Linux?

OK gang, need to 'flash' superboot to SD card. don't have Winders.

Tried wine but program doesn't see the SD card.

What other options do I have?? What does SD-flasher really do?
Can I just use DD??

This tool works under WINE-emulator

So how do I get it to see the SD card??

I confirm. SD-flasher works with Wine but doesn't detect the SD Card. Even
if SD-flasher is launched from the SD-Card.
Wine detetcs all the volumes, but SD-flasher doesn't.
Is there any way to flash the card from GNU/Linux ? I have no W$ box.
I tried dd but mini6410 doesn't boot.

Thanks for help.
