Ultra DMA/66/100 Reference 66
Hard drives that support Ultra ATA/66/100 also support Ultra ATA/33
and multi-word DMA, and can be used with existing multi-word DMA
host chipsets. Installed PCs without Ultra ATA/100 capability can use
new hard drives in legacy ATA modes at transfer rates up to 33.3 MB/s.
However, by upgrading with an Ultra ATA/100 PCI adapter card and
80-conductor cable, they can also take advantage of the interface’s
newer speed and data integrity features. Bus timings must be scaled to
transfer up to twice as fast. PC vendors who would like to incorporate
the advantages of Ultra ATA/100 in new systems can do so by using
new chipsets and motherboards from Intel and other leading vendors
that license the technology. Although a new cable is required for Ultra
ATA/66/100, the chipset pin count remains the same at 40.
System Requirements for Ultra ATA/66
To use the Ultra ATA/66/100 technology, a system must have:
z
Ultra ATA/66/100 compatible logic either on the system
motherboard, or on an Ultra DMA PCI adapter card
z
Ultra DMA compatible BIOS
z
DMA-aware device driver for the operating system
z
Ultra ATA/66/100-compatible IDE device such as a hard
drive or CD-ROM drive
z
40-pin 80-conductor cable
