It intercepts calls to hddisk.device, and checks for the presence of a hi-res,
interlaced screen of a certain depth, which is likely to cause the infamous
retries on the SCSI bus. If it finds there is going to be contention, it fudges
the MaxTransfer value to prevent long, uninterrrupted reads. Since the entire
read need not be retried if contention occurs, things get considerably faster.

It is a kludge, and the method used is not exactly kosher (the MaxTransfer
value the driver actually uses is not stored in a place where nice programs
go), but it works. I'll see if I can get it mailed off to Bob.
