The use of seabios defconfig kills boot performance of Windows guests because the default is for the int13 handler to use PIO when accessing the emulated IDE device. By instead using a canned configuration with the ATA settings overridden to enable DMA access (and also wider PIO) boot performance is markedly improved without the need to use a different (and possibly not supported) device model. This patch adds the canned configuration into tools/firmware and modifies the Makefile rule to copy it into place.
