ATA Specification Family


The ATA specification is commonly used for IDE hard disks and CD-ROM drives. In recent years, its scope has expanded to include other forms of removable media as well.

AT Attachment Interface with Extensions (ATA-2)


"This standard defines an integrated interface between devices and host processors. It provides a common point of attachment for systems manufacturers, system integrators, and suppliers of intelligent devices."... The ATA interface is the commonly used interface for attaching IDE hard disks and ATAPI CD-ROM drives.

AT Attachment-3 Interface (ATA-3) Specs


This standard documents the new version of the ATA Interface, version 3.

Serial ATA: High Speed Serialized AT Attachment Spec 1.0 - by Serial ATA Workgroup


"The purpose of this document is to provide a technical specification of a high-speed serialized ATA data link interface." Serial ATA is defined with the following goals and requirements listed in no particular order: Primary inside-the-box storage connection, completely compatible with ATA, low pin count for both host and devices, low voltage, supports lower cost device architectures, higher performance than equivalent ATA.

Small Computer System Interface - v2 (SCSI-2)


"This standard defines mechanical, electrical, and functional requirements for attaching physically small computers with each other and with intelligent peripherals such as rigid disks, flexible disks, magnetic tape devices, printers, optical disks, and scanners. The resulting interface facilitates the interconnection of physically small computers and intelligent peripherals and thus provides a common interface specification for both systems integrators and suppliers of intelligent peripherals."

Plug & Play SCSI Specs


"The Plug and Play SCSI effort was undertaken as an extension to Plug and Play ISA. Microsoft encouraged host adapter manufacturers to participate in this effort to develop an easy to use SCSI environment in the personal computer marketplace."

Fibre Channel Arbitrated Loop Specs


"This Profile specifies Fibre Channel and SCSI-3 options to ensure interoperability between SCSI Initiators and Disk Targets on a private Loop (no Fibre Channel fabric attached)."

Universal Serial Bus Specs


"This document defines an industry standard Universal Serial Bus. The specification describes the bus attributes, the protocol definition, types of transactions, bus management, and the programming interface required to design and build systems and peripherals that are compliant with this standard."

FreeBSD USB Home Page - by Nick Hibma


Lots of information about USB, from the BSD front. This site contains lots of documentation, code, and actual working drivers... get involved, or get direction!

PCI and AGP Local Bus Info


"This page is dedicated to programming & other technical information about the PCI and AGP Buses. This is information that you CANNOT get for free from the PCI SIG; they want to charge you exorbitant amounts of money for the info."

PCI BIOS Specs - by PCI Special Interest Group


"This document describes the software interface presented by the PCI BIOS functions. This interface provides a hardware independent method of managing PCI devices in a host computer. This document is intended to provide enough information to software developers to utilize PCI devices in a host computer withut any knowledge of how the actual hardware performs the desired functions."
