Windows系统多重启动的五个重要文件

本文将分析在多重启动系统中起重要作用的文件,它们分别是以下几个:BOOT.INI、BOOTFONT.BIN、BOOTSECT.DOS、NTDETECT.COM、NTLDR。其中BOOT.INI是大家非常熟悉的一个配置文件。从这个文件可以选择启动的操作系统是什么?而且还可以通过修改BOOT.INI文件控制启动的方式,如在操作系统说明符后面加上“/fastdetect”参数,可以使用快速自检模式。同样,还有“/nodetect”等参数可供使用。但是,不是说没有这个文件就不能够启动你的操作系统,丢失这个文件的后果就是只能从C盘启动。同时,由于这个文件是完完全全的一个文本类型的文件,我们可以使用任何文本编辑工具编辑这个文件。换句话说,BOOT.INI在多重启动系统中不是最重要的一个文件,也就说不上“备份双系统启动文件只要备份C盘根目录下的BOOT.INI文件就可以了”。熟悉多重启动系统启动模式的朋友们都知道,操作系统的启动流程从NTLDR开始。NTLDR通过读取BOOT.INI文件,确定操作系统启动分区的位置。对于只有一个操作系统的电脑,NTLDR启动NTDETECT.COM开始下一步的启动流程,而对于含有多重启动操作系统的电脑,NTLDR将把BOOT.INI的选择菜单内容显     

一种新的语音二项式正弦脉冲激励方案

本文提出一种新的用于LPC语音编码器的BSP激励信号，即根据语音产生的原理，以一个幅度受到二项式调制的正弦波BSP（Binomial Sine Pulse)作为LPC激励源，该二项式反映了激励信号在一个基音周期内的变化趋势。本文同时推导了BSP激励参数的求取和改进方法。实验结果表明，在此基础上构造的BSP语音编解码器具有低复杂度、低时延的优点，同时编码速率在低至2．65kb/s时，具有较高的合成语音质量。     

linux下ARM的交互开发设计研究

随着ARM芯片以及LINUX操作系统的出现,为嵌入式的发展注入了强劲的活力。本设计实现LINUX操作系统向ARM9平台的移植。U-boot是系统的启动引导程序,要移植LIUNX操作系统,U-boot是必不可少的。LINUX操作系移植成功后,系统还是不能正常启动的,还需要根文件系统（rootfs）支持,这样系统就可以正常启动。但是嵌入式系统往往是为某些特定的功能设计的,所以,系统要想完成某些功能,还需要顶层应用程序的支持。

浅谈Windows启动速度缓慢的原因

W indows以其稳定的性能成为大家首选的操作系统,但在使用过程中你会发现,随着时间的推移,操作系统在速度上越来越慢了。特别是启动速度,常常要等待好长一段时间,甚至一开机就死机的情况时有发生。W indows启动速度缓慢的原因很多,以下笔者根据日常使用中所遇到的问题分析出几种原因,仅供大家参考。1.网卡:网卡的设置非常重要,如果设置不当,会严重影响系统启动速度,甚至会导致系统死机,如果用户设置成“自动获得IP地址”,系统在启动时就会不断地在网络中搜索DH CP服务器,直到获得IP地址,这就直接影响了启动时间,因此,局域网用户最好为自…
