The remaining connector s plug into storage devices, most commonly hard disk drives or optical drives. Older operating systems, such as Windows 98 , do not support bit LBA at all. It specifies provisions in the BIOS of a personal computer to allow the computer to be bootstrapped from devices such as Zip drives , Jaz drives , SuperDisk LS drives, and similar devices. The Information for Your Computer Questions. Pin one is at bottom left of the connectors, pin 2 is top left, etc.

I have molex connectors, but I don’t atpai if I should connect the DVD drive to them as-is they’re all connected to each other; see the “cables” pictureor if I should take them apart and use one to connect the DVD drive to the yellow or dark blue ports near my bright blue primary IDE port in the top left-ish area of the second picture. This arrangement eventually was standardized in later versions.

When the CD-ROM was developed, many computers would have been unable to accept these drives if they had been ATA devices, due to already having two hard drives installed. Interfaces are listed by their speed in the roughly ascending order, so the interface at the end of eise section should be side fastest. Motherboard vendors still wishing to offer Parallel ATA with those chipsets must include an additional interface chip.

There is an attempt limit, normally set to 5, after which the disk must be power cycled or hard-reset before unlocking can be attempted again. From Wikipedia, the free encyclopedia. Archived from the original PDF on Although they are in extremely common use, the terms “master” and “slave” do not actually appear in current versions of the ATA specifications.


The ATA-4 and subsequent versions of the specification have included an “overlapped feature set” and a “queued feature set” as optional features, both being given the name ” Tagged Command Queuing ” TCQa reference to a set of features from SCSI which the ATA version attempts to emulate. This one tip will help you eie better tonight A few seconds are all you need to get a better night’s rest.

The stub causes signal reflectionsparticularly at higher transfer rates. I have the same question 3. How satisfied are you eidf this reply?

Does IDE support EIDE/ATAPI ? – Forums – CNET

This is what my computer looks like: Transmission of command and status blocks do not use the fast signaling methods that would necessitate CRC. Furthermore, sustained transfer rate tests do not give realistic throughput expectations for most workloads: This implementation resulted in excessive CPU utilization which largely negated the advantages of command queuing.

For ease of reach from motherboard to device, ekde connectors tend to be positioned towards the front edge of motherboards, for connection to devices protruding from the front of the computer case.

AT Attachment Computer storage buses Computer connectors. Pin 28 is only used to let the drives know their position on the cable; it is not used by the eive when communicating with the drives. It included most of the features of the manufacturer-specific variants. Please try again now or at a later ejde.


The function of serializing requests to the interface is usually performed by a device driver in the host operating system. Only one device on a cable can perform a read or write operation at one time; therefore, a fast device on the same cable as a slow device under heavy use will find it has to wait for the slow device to complete its task first.

Pin 34 is connected to ground inside the blue connector of an conductor cable but not attached to any conductor of the cable.

A device can have two passwords: The motherboard has 4 SATA ports. The gray center connector omits the connection to pin 28 but connects pin 34 normally, while the black end connector connects both pins 28 and 34 normally.

I have a EIDE/ATAPI DVD drive. How do I install it?

CNET’s Forum on PC eude is the best source for finding help, troubleshooting, and getting buying advice from a community of experts.

If a device is locked, it will refuse all access until it is unlocked. You can atxpi the question or vote as helpful, but you cannot reply to this thread. Let me know if that doesn’t make sense and I’ll put a picture up on the blog. Retrieved from ” https: In other projects Wikimedia Commons.
