In protected mode, to make a DMA buffer, one must allocate memory under
1M, correct? This memory cannot cross page breaks right? So in protected
mode, where there are no page breaks, does it matter where the DMA
buffer is as long as it under 1M? If it does matter, how do you find if
it crosses a page break?
