常見的接口:1、并行接口(每一次傳送一個(gè)字或字節(jié)的全部代碼)INTEL 8255,MC6820,Z80_PIO,傳送的距離比較近。 2、串行接口:數(shù)據(jù)和控制信息是一位一位串行地傳送下去,距離比較遠(yuǎn),通常COM1使用是9針D形連接器,COM2使用是老式的DB25針連接器, 3、磁盤接口 (1)IDE接口,集成驅(qū)動(dòng)器電子部件,不支持DMA數(shù)據(jù)傳送,只使用標(biāo)準(zhǔn)的PCI/O端口指令來傳送所有的命令,狀態(tài)等 (2)EIDE接口, 4、Scsi接口。具有多任務(wù)接口,具有總線仲裁功能。按同步或異步方式傳輸數(shù)據(jù),可分單端和差分傳送方式,是智能化設(shè)備。 5、USB接口。

USB海量存儲(chǔ)設(shè)備類規(guī)范包括四個(gè)獨(dú)立的子類規(guī)范:(ATA command的那個(gè)沒有) ①USB Mass Storgage Class Control/Bulk/Interrupt(CBI)Transport ②USB Mass Storage Class Bulk-Only Transport ③USB Mass Storage Class ATA Command Block ④USB Mass Stroage Class UFI Command Specification。 前兩個(gè)子規(guī)范定義了數(shù)據(jù)/命令/狀態(tài)在USB上的傳輸方法。 Bulk-Only傳輸規(guī)范僅僅使用Bulk端點(diǎn)傳送數(shù)據(jù)/命令/狀態(tài), CBI傳輸規(guī)范則使用Control/Bulk/Interrupt三種類型的端點(diǎn)進(jìn)行數(shù)據(jù)/命令/狀態(tài)傳送。 后兩個(gè)子規(guī)范定義了對(duì)存儲(chǔ)介質(zhì)的操作命令。 ATA 命令規(guī)范用于硬盤。 UFI命令規(guī)范是針對(duì)USB移動(dòng)存儲(chǔ)而制定的,實(shí)際上UFI命令格式是基于SFF-8070i和Scsi-2規(guī)范,總共定義了19個(gè)12字節(jié)長度的操作命令。

2.0.12 (May 13th, 2004) - Flag driver threads with PF_FREEZE to support software suspend. 2.0.11 (May 7th, 2004) - Avoid split-completion bugs in certain PCI-X chipsets by breaking up large completion entry DMAs on ADB boundaries. 2.0.10 (April 9th, 2004) - Return "command timeout" status instead of "selection timeout status" to the Scsi mid-layer in response to selection timeouts. While the latter may seem more correct, the mid-layer will not offline devices suffering from persistent selection timeouts. This leads to extremely long recovery times for devices that go missing. Returning command timeout status causes the mid-layer to enter recovery and eventually offline persistently missing devices.

This sample provides a generic example of a PCI IDE minidriver. The sample isolates vendor-specific code from the higher-level PCI IDE bus driver, much as Scsi minidrivers isolate code from the Scsi port driver. See the Release Notes section for more information. This sample works on both x86 and Alpha platforms, and is 64-bit compliant. It builds with Microsoft® Visual C® 6.0. It does not implement Plug and Play or Power Management.

This directory contains the miniport driver for INI-9100U/UW PCI_UltraScsi Bus Master Controllers. This driver exports several functions that are used by Scsiport.sys to issue Scsi requests to the devices attached to the controller, process adapter interrupts, and various other Scsi activities. This driver is also responsible shutting down the controller during device removal or power management operations.
