请问DBLSPACE有什么用？

metero 2002-09-13 10:53:07

我的系统是WIN98，当我在启动的时候选COMMAND PROMPT ONLY的时候，
我用MEM/C/P查看内存的时候，发现DBLSPACE占用了110K的基本内存。
让我有些DOS程序不能运行。
请问它有什么用？可以去掉吗？如何去掉？
我的硬盘分为 C：6G，D：10G，E：24G。

你还顺杆爬呀，哼。
上述情况只对98有效，升级到2k/xp之前删，之后？你愿意也可以，我不负责～～

错了，是NTLDR

DOS 6.22 以後与 Win 95 都改用了 DRVSpace, DBLSpace 的设置是为了考虑到 DOS
6.2 以前的使用者以 DBLSpace 压缩过的硬碟来升级 Win95 的系统後可能发生的不相容问题. 详细解说可以看看 DOS 的 Help~

如果你不用 DBLSpace 或 DRVSpace
在 MSDOS.SYS 的 [Options] 中加入
DRVSPACE=0
DBLSPACE=0

最简单的方法是：对于98系统，把根目录下除了io.sys msdos.sys command.com config.sys autoexec.bat之外的所有文件（包括隐藏、只读、系统文件等）统统删掉！！绝对安全，不产生任何问题，可以正常使用modem和宽带、局域网等。然后查找所有名字为dblspace.*和drvspace.*的文件，删掉！！这样dblspace和drvspace两种压缩硬盘的工具都不可能加载了。而且根目录下的文件越少系统越优化。
顺便说一句：因为这些磁盘压缩工具只支持fat，你的C盘分区是6G，显然是fat32，所以想用也没得用啦～～

dblbuffer=1
是设置dblspace缓冲的。

应该是你的98安装盘的问题。
换最新的98看看，不要用OEM版的。

dblspace 我并没有加载啊，怎么会有呢？

那我的硬盘是压缩了的吗？
我打开msdos.sys,其中有一句：
dblbuffer=1; 这又有什么意思呢？

是用来压缩磁盘的……

这个是dos时代用的，现在用的少了。不过你可以把它放入高端内存中，这样就不会占用常规内存了。

本人收葳以久的 config.sys SMARTDRV.EXE HIMEM.SYS diskgen.exe DOS三个基本启动文件COMMAND.COM MS-DOS.SYS IO.SYS 启动DOS用到的文件描　　述：IO.SYS是dos环境控制输入输出的文件，不可以少。 COMMAND.COM是Windows 9X中的DOS外壳程序(SHELL)，较DOS 6.22仅增加了部分内部命令，没有更新的东西。　　IO.SYS对COMMAND.COM的处理则有了根本改变，当Win 9X在CONFIG.SYS中加载EMM386.EXE驱动提供UMB时，COMMAND.COM的常驻部分装入HMA，暂驻部分装入UMB中(在DOS6.22中，COMMAND.COM只能将常驻部分装入HMA)，这将为DOS程序提供更大的常规内存，也不需要反复从磁盘中恢复暂驻部分，有效地提高了系统性能。当然，如果没有加载EMM386.EXE，系统不提供UMB，COMMAND.COM的暂驻部分就只能象DOS6.22那样置于常规内存的高端。　　DOS内部命令的程序代码存放在command.com文件中，它在DOS系统启动的时候随DOS的启动模块一起被调入计算机内存。 MSDOS.SYS是DOS的三个核心文件之一，另外两个是command.com、IO.SYS 　　MSDOS.SYS 在微软非NT内核的操作系统中经常可以看到它,具有只读、系统、隐藏三个属性，因此在WINDOWS中是看不到的，可以通过“文件夹选项”中“显示系统文件”和“显示所有文件”来显示它，如果改它的属性在WINDOWS中只能改只读和隐藏两个属性，不能改系统属性，但是可以在命令行形式下改attrib -s msdos.sys 　　MSDOS.SYS可以修改，但改坏了可能会导致系统无法启动，可以用记事本打开，内面是一些启动参数，如：开机时显示不显示菜单、开机时进行磁盘扫描吗、开机时显不显示LOGO等等。　　1、MSDOS.SYS的作用　　在Win 9X中，MSDOS.SYS变成了纯文本系统配置文件，用于控制Win的启动方式。可以在DOS模式下解除其特殊属性(只读、隐藏、系统)，根据需要自行配置。MSDOS.SYS可以是空文件，甚至可以删除，当然此时系统只能以纯DOS方式启动，不能进入GUI系统。　　不同方式形成的MSDOS.SYS默认内容不同，主要有四种，其中前三种方法形成的MSDOS.SYS文件无任何配置命令，几乎是空文件，仅保留一行注释，以说明该文件形成方式，这类文件多见于系统软盘中。不同的MSDOS.SYS内容如下：　　1)Win安装时建立的系统盘 : ;Win95EBO 　　2)FORMAT /S建立的系统盘 : ;FORMAT 　　3)SYS A：传递建立系统盘 : ;SYS 　　4)建立系统时在硬盘上形成的MSDOS.SYS 　　系统硬盘中的MSDOS.SYS内容比较完整，包括必要的启动配置命令，文件长度必须大于1024 bytes，即占用两个以上磁盘扇区，这一要求在该文件中说明为保证兼容性，但从未见更深入的介绍，实际上文件小于1024 bytes对系统并无明显影响，该要求估计是为了保证系统与旧版DOS和Win 3.X兼容而提出的，这一点尚望行家指教。　　用SYS向硬盘传送系统以修复启动文件时，将覆盖引导记录、IO.SYS和COMMAND.COM，MSDOS.SYS的内容保持不变，保证系统引导部分修复后，整个系统仍能正常启动，这一做法非常聪明。　　2、MSDOS.SYS的配置参数　　MSDOS.SYS由三小节组成，其各配置参数无顺序要求，内容如下：　　[PATHS] 　　指定Windows的系统文件路径　　WinDir＝　　指定Win 9X各系统文件及其子目录所在的目录　　该路径必须包括注册表文件SYSTEM.DAT和Win 9X启动必需的驱动程序，如HIMEM.SYS等　　WinBootDir＝　　指定Win 9X的GUI启动程序Win.COM所在的目录　　HostWinBootDrv＝指定Win.COM所在的驱动器，不需冒号(:) 　　UninstallDir＝　　指定保存原系统的目录，便于自身删除时恢复原系统用　　该参数出现在Win的升级版本中　　[OPTIONS] 指定Windows的启动方式，/前的值为缺省值　　LOGO＝1/0 　　允许/禁止启动时显示Win 9X标志(LOGO) 　　屏蔽该画面有时可解决第三方内存管理程序造成的冲突　　看到系统启动过程出现的提示信息，也使系统启动稍快，启动　　启动时可用ESC键清除Win 9X标志，查看实模式启动信
