USB啟動盤制作軟件 市面上現在大多數U盤都支持啟動機器的功,但是要制作啟動型U盤,需要進入WIN98,現在很多人機器上都沒有98了吧,呵呵。為了做個啟動盤,裝一個98,多冤啊。這個小軟件就是為此編制的,在WIN2K/XP下運行,可以直接把U盤做成啟動盤。程序自帶了MSDOS7.1的兩個 基本啟動文件IO.sys和COMMAND.COM,如果要制作復雜的啟動盤,可以把其他文件拷貝到U盤上即可,比如HIMEM和CONFIG.sys什么的。

計算機接口技術系列 Visual C++串口通信技術與工程實踐 在編譯本章程序后,請將winio.dll、winio.vxd和winio.sys文件復制到可執行文件所在目錄下, 否則WinIo庫初始化函數initializeWinIO調用將會失敗。

RTEMS (Real-Time Executive for Multiprocessor systems) is a free open source real-time operating system designed for embedded systems. The acronym RTEMS initially stood for Real-Time Executive for Missile systems, then became Real-Time Executive for Military systems before changing to its current meaning. RTEMS development began in the late 1980s with early versions of RTEMS available via ftp as early as 1993. OAR Corporation is currently managing the RTEMS project in cooperation with a Steering Committee which includes user representatives.

This project attempts to implement a Database using B+Tree. The project has developed a DATABASE sysTEM with lesser memory consumption. Its API includes simple SQL Statements and the output is displayed on the screen. Certain applications for which several features of existing databases like concurrency control, transaction management, security features are not enabled. B+Trees can be used as an index for factor access to the data. Help facility is provided to know the syntax of SQL Statements.

首先要說的是,要進行DOS下的環境配置,基本上不可避免要使用到config.sys和AUTOEXEC.BAT這兩個文件。Config.sys文件是一個專業的系統啟動配置文件,它主要用于加載內存管理程序、設置擴充內存及擴展內存、加載有關硬件驅動程序,設置有關環境變量等,為用戶計算機的正常使用創造必要的用戶環境(在DOS時代,精通Config.sys文件往往是“專家”的標志)。(在Windows 95/98中,系統已經自帶了內存管理、環境變量等設置功能,Config.sys文件的作用已經遠遠沒有那么重要了,它仍在“服役”的原因主要是為了保持對老版本DOS應用程序的兼容)

編譯時需要Windows98 DDK 或 Windows 2000 DDK 及 VC 6.0,SoftIce 4.0(推薦) 另外,在編譯中要改變路徑設置,缺省時為e:\tan\hellow\hellowdm,DDK,SoftIce的路 徑也要正確。 編以后,啟動控制面版中的“添加新硬件”,選擇“其它設備”,點擊“從磁盤安裝” 在找到上述目錄下的hellowdm.inf,在安裝中指定hellowdm.sys的路徑即可。 安裝好后可在控制面板的“系統”中看到此設備。 文件說明: hellowdm.dsw 為主工作文件 testhello目錄 為客戶端程序
