DMA Error with SmartDrv and QEMM

If DiskDupe sometimes reports a DMA error when it is buffering to the hard disk with SmartDrv (the one that came with Windows 3.1) and QEMM 6.01, put DB=3 and DMA=15 on the QEMM386.SYS line to reserve 3k for disk buffering and 15k for DMA buffering.

This will usually happen only on computers with SCSI drives.
