那位高人可以指点一下dos启动后要求访问A：区的问题！！！ - 中国DOS联盟论坛

各位大侠
我有双硬盘，现在想把第二块硬盘上安装dos，用主盘的虚拟软盘启动dos7.1 sys到从盘，然后把img里面的其他的文件放到从盘里，不知什么原因，可以启动，但是运行外部命令时总是提示A：盘有问题，我仔细拜读了两个启动的文件怎么也没有找到那里需要读取A：呀!可否指点一下是哪个命令
另外命令行最后 > NUL时什么意思？？？
另外把我自己修改以后的文件如下，主要就是修改了文件路径！！

能不能把错误提示完整的写出来？可能的原因：1、搜索路径中将A:排在了前面。 2、comspec变量设置在A盘了。（不过批处理中有相关的设置语句，可能没有生效）。建议你使用msdos 7.10的完整安装版将dos 7.10安装到硬盘上，因为软盘版和硬盘版是不同的。

用虚拟软盘启动的，当然默认工作目录就是A：，你的外部命令放到从盘的呀，在运行外部命令后，系统需要A：的COMMAND。COM来返回，而此时的目录却不是A：，所以系统找不到COMMAND。COM，就提示出错。可能是这个原因吧。。

>nul 就是不显示程序运行信息，也就是把显示信息输出到空设备nul中。

好像也不是呀，我是先从主盘把用虚拟软盘启动dos7.1 sys到从盘，然后把主盘拔掉了以后在单独用从盘启动的！！另外所有的path里面都没有A：SET COMSPEC=%RAMDRIVE%\SYSTEM\COMMAND.COM并不A：呀！！！我始终怀疑是不是IO.sys msdos.sys有问题！！！！！

%RAMDRIVE%的实指就是A:,所谓虚拟软盘程序就是把某个文件夹模拟成A:,因为软盘的盘符就是A(可能,当A盘符出现故障或未用时,比如,坏了,或在BIOS禁用了,就转成B了...)

晕，不要听楼上的。楼上的能不能对自己不明白的不要乱说？RAMDRIVE是内存虚拟磁盘的盘符，其盘符一般是从C开始分配的（一般排在硬盘最后一个盘符和光驱盘符中间），不可能是A或者B，就算是A或者B，只要虚拟磁盘正确建立了，也不会导致“Not ready drive A:”的错误提示。楼主更晕，我让你把进入DOS后执行path命令的结果放上来，不是让你从自动批处理中把path的设置拷贝出来（这个我自己会看）。操作步骤：启动进入DOS，在提示符下运行命令：path然后将该命令的执行结果放到这里！

俩位说得好像都有问题！%RAMDRIVE%在我的机器里面好像是E：我用step by step 的办法看到启动xmsdsk以后指示的盘符位E：，我的从盘另外有一个分区！既然如此，path里面也不会出现A：了path＝e.;e:\SYSTEM;c:\dos;c:\;c:\boot\;c:\boot\ebd;c:\boot\ebd\batC:.;c:\boot\ebd\inf;c:\boot\all;不过GOTOmsdos大侠的办法倒是可以我把SET COMSPEC＝c:\SYSTEM\COMMAND.COM以后就可以解决问题了谢谢各位热心的大侠了额！！！！！！！！！！

楼主注意：我在第一个回复中就指明了有可能是comspec设置错误。
