Memory Cache - TYAN Tempest i5400XL User Manual

Ultra DMA Mode
Enables or disables Ultra DMA Mode.
Ultra DMA (UDMA, or, more accurately, Ultra DMA/33) is a protocol for transferring
data between a hard disk drive through the computer's data paths (or bus) to the
computer's random access memory (RAM). The Ultra DMA/33 protocol transfers
data in burst mode at a rate of 33.3 MBps (megabytes per second), twice as fast as
the previous Direct Memory Access (DMA) interface.
Ultra DMA support in your computer means that it will boot (start) and open new
applications more quickly. It will also help users of graphics-intensive and other
applications that require large amounts of access to data on the hard drive. Ultra
DMA uses Cyclical Redundancy Checking (CRC), offering a new level of data
protection.
Because the Ultra DMA protocol is designed to work with legacy application PIO
and DMA protocols, it can be added to many existing computers by installing an
Ultra DMA/33 Peripheral Component Interconnect adapter card. Ultra DMA uses
the same 40-pin Integrated Drive Electronics interface cable as PIO and DMA.
