*Transfer Modes Supported

• PIO Mode or Programmed Input/Output Mode is the most common way computers trans-

fer data to and from the disk drive. PIO Mode 4, which is the mode installed, differs only

from the standard PIO transfer in how often the drive issues interrupts. In PIO Mode 4, each

interrupt indicates the drive is ready for 4 sectors of data (read) or has completed the trans-

fer of 4 sectors of data (write), compared with the one interrupt required in standard PIO for

each sector. This eliminates some of the system overhead involved in a PIO transfer.

• DMA (Direct Memory Access) Mode is used in EISA-, VESA Local Bus-, and PCI-

equipped systems. This mode is capable of very fast transfer rates using Bus Mastering.

The advantage of using the Bus Master DMA is that it uses less CPU resources than PIO

and therefore, it is useful in multitasking environments, where the CPU can work on a

different program while data is transferred to or from IDE devices, such as hard disk or

CD-ROM drives. Ultra DMA, which is the mode installed, is also known as Ultra-ATA

(ATA is the “official” name for what the computer industry calls IDE or Integrated Drive

Electronics) or Ultra-DMA/33. It is the latest advancement to the ATA specifications.

Ultra-DMA, among others, almost doubles the maximum transfer speed of the ATA-3

standard and improves data integrity.
