Are you sure it will be significantly faster?  AFAIK, the BIOS is one of 
the causes of the slow real-mode disk I/O, because it ties the processor 
until the operation completes.

Going to the BIOS level also means CWSDPMI will have to implement a disk
cache (because third-party caches operate at the DOS/IOCTL level); 
without a cache I think you will see a slow-down rather than a speed-up.
