It's just a normal blindflash, in the past we had to use PCI cards to get the systems to boot to DOS, but these days, mid/high end motherboards are equiped with more then 1 PCIe 16x slots. All you have to do in BIOS is to set what is the primary PCIe slot, if you don't use the first one as default. In case your motherboard has just one PCIe 16x slot, have no fear, find an old PCI card, set it in BIOS as the primary display, and flash the bricked card.
