XDMA UDMA driver
(ver 3.3)
Abandoned Freeware


Even though a motherboards BIOS may support UDMA (i.e, ATA/33, ATA/66, 
ATA/100, etc.), DOS does not have any way to natively access a drive using 
a UDMA mode.  XDMA is a small Driver that extends the capability of DOS so 
that it can now use UDMA to speed data transfers to and from UDMA drives.
