bootable usb - from leopard

[Guest dtizzle]

With help from related topics I know use an MSI Wind running Leopard as my primary machine. I am interested in attempting some bios updates (official and unofficial), but would like to know how to flash the bios using a stick formatted in Leopard.

Do I have to go into terminal in order to prep a USB stick to be bootable?

Any help would be greatly appreciated.
