  Log:
  SVN rev 189749 on 2009-03-12 20:41:52Z by jhb
  
  The recent change to use memory > 1MB for the heap by default broke CD
  booting because the CD driver did not use bounce buffers to ensure
  request buffers sent to the BIOS were always in the first 1MB.  Copy over
  the bounce buffer logic from the BIOS disk driver (minus the 64k boundary
  code for floppies) to fix this.
