IDE stands for Integrated Drive Electronics
A hardware interface widely used to connect hard disks, optical discs and tape drives to a PC. Introduced in 1986 with 20MB of storage, capacities increased a thousandfold in less than two decades. Compared to the SCSI interface, IDE has been the more economical choice.
(Direct Memory Access) Specialized circuitry or a dedicated microprocessor that transfers data from memory to memory without using the CPU. Although DMA may periodically steal cycles from the CPU, data are transferred much faster than using the CPU for every byte of transfer. On PCs, there are eight DMA channels commonly used as follows. Most sound cards are set to use DMA channel 1. See PIO mode.
DMA Used for
0 8-bit transfer
1 8-bit transfer
2 Floppy disk controller
3 8-bit transfer
4 Cascaded from 0-3
5 16-bit transfer
6 16-bit transfer
7 16-bit transfer
DMA Disk Transfers There are various modes of data transfer on IDE disk drives. The PIO modes use the CPU, and the DMA modes bypass the CPU.
DMA is the same thing as bus-mastering.
yes. pata and ide are the same thing.
ATA and IDE use the same interface type, so the answer is YES, you can put the a ATA and an IDE in the same computer.
DMA operations
DMA - magazine - was created in 1993.
DMA - magazine - ended in 2003.
DMA Distribuidora was created in 1950.
its the same process as u set up a SATA drive... the first thing to do is to remove the jumper from the drive and then use the IDE cable to connect it with it. then go to the drive options and set it to serve as the main.
i think it is a slave device because i am guessing Answer 2: You can configure the ROM as either Master or Slave; as long as you have the ability to select the boot device from the BIOS, if you do not have that ability then the computer may not boot. Please note however that most CD / DVD ROMS are slower than hard drives, and the normal IDE channel cannot communicate any faster than the slowest device in the chain. In detail: If you have a DMA Mode 1 CD ROM and a UDMA Mode 4 IDE Hard Drive, the hard drive cannot talk to the motherboard any faster than DMA Mode 1. It is always a wise choice to put the CD / DVD ROM as "Slave" on the secondary IDE channel (if available).
Yes, DMA does bypass the CPU.
DMA transfers data directly from the drive to memory without involving the CPU. PIO involves the CPU and is slower than DMA mode.
DMA (Direct Memory Access) does not actually interrupt the CPU - it requests control of the bus, so that it can perform the transfer itself. It becomes a bus-master. This is done using the HOLD and HLDA (Hold Acknowledge) control pins. This is not the same thing as an interrupt, which is where an external device requests the CPU's attention, and the CPU goes off and performs some code to service that request. In the case of DMA, the CPU actually freezes for the few cycles that the DMA controller requires, which is much, much more efficient than using an interrupt service routine.
