- For chipsets that can't do 64k transfers, fall back to 32k transfers

Browse Source 
(still a power of 2) rather than 63k transfers.  Even with 63k transfers
  some machines (such as Dell SC1435's) were experiencing chronic data
  corruption.
- Use the MIO method to talk to the Serverworks HT1000_S1 SATA controller
  like all the other SATA controllers rather than the compat PATA
  method.  This lets the controller see all 4 SATA ports and also
  matches the behavior of the Linux driver.
