Indeed ... seems to be pretty fast via INT $13

But how is it done ? They support DMA and USB storage - but where do they take the memory ? DMA drivers always need XMS, DOS USB drivers always have memory problems, and mostly do require XMS, or even worse EMM386

How do the new "dead" BIOS'es do "without" memory ?
