  Log:
  Implement a workaround of the datacorruption problem on serverworks HT1000 chipsets.
  The HT1000 DMA engine seems to not always like 64K transfers and sometimes barfs data all over memory leading to instant chrash and burn.
  Also fix 48bit adressing issues, apparently newer chips needs 16bit writes and not the usual fifo thing.
