『楼主』: msdos710软盘启动以后自动调用硬盘上win98的方法探讨使用 LLM 解释/回答一下

斑竹的msdos710启动盘很好用，但是如果要想运行硬盘上的windows98就需要手动进入windows98安装路径，运行之，小女子写了一个ndos的批处理程序用来自动调用硬盘中的win98.
工作原理如下：程序先找到c:\msdos.sys，然后通过循环方式对msdos.sys文件中的每一行文字进行一一排查，如果找到“WinDir=”语句，就将其设置为变量，并退出循环，根据windir的对应值找到win98的安装路径，并运行win98.

在此抛砖引玉，希望大家多多努力。这个程序也可以使用xset代替ndos完成。

其中涉及到的几个ndos内部函数如下：
%@lines 用于返回文件的行数
%@line 用于返回文件指定行的内容
%@len 用于返回字符串的长度
%@eval 用于返回+-*/运算的结果
%@substr 用于返回字符串起始位置开始的n个字符
%变量名称% 返回变量内容

要想在msdos710环境运行可以输入“ ndos /c loadwin ” 运行

loadwin.bat 程序内容如下：
*********************************************
@echo off
setlocal
if not exist c:\msdos.sys goto error
set x=%@lines
set y=0
:loop
set winx1=%@line
if %y%*==%x%* goto error
set l=%@eval-7]
set winx=%@substr
if #%winx%#==#WinDir# goto setdir
set y=%@eval
goto loop

:setdir
set winx2=%@substr
set winx3=%@substr
%winx3%
cd %winx2%
path %winx2%;%winx2%\command
set x=
set y=
set l=
set winx1=
set winx2=
set winx3=
set winx=
WIN /D:N
:error
echo ERROR ! windows_9x_Path unknowed !!!
echo 1.THERE IS NOT C:\MSDOS.SYS!
ECHO 2.C:\MSDOS.SYS can not load Windows9x!
ECHO Press any key to continue!
PAUSE>NUL
goto end
:end
endlocal
quit
***************************************************

The moderator's msdos710 boot disk is very useful, but if you want to run Windows 98 on the hard disk, you need to manually enter the Windows 98 installation path and run it. The little girl wrote a batch program of ndos to automatically call Windows 98 on the hard disk.

The working principle is as follows: The program first finds c:\msdos.sys, then checks each line of text in the msdos.sys file one by one in a loop. If the "WinDir=" statement is found, it is set as a variable and the loop is exited. According to the corresponding value of windir, the installation path of Windows 98 is found and Windows 98 is run.

Here, I'm just putting forward a simple idea, hoping that everyone will work hard. This program can also use xset instead of ndos to complete.

The following are several internal functions of ndos involved:
%@lines Used to return the number of lines of the file
%@line Used to return the content of the specified line of the file
%@len Used to return the length of the string
%@eval Used to return the result of +-*/ operations
%@substr Used to return n characters starting from the starting position of the string
%variable name% Returns the content of the variable

To run in the msdos710 environment, you can enter "ndos /c loadwin" to run

The content of the loadwin.bat program is as follows:
*********************************************
@echo off
setlocal
if not exist c:\msdos.sys goto error
set x=%@lines
set y=0
:loop
set winx1=%@line
if %y%*==%x%* goto error
set l=%@eval-7]
set winx=%@substr
if #%winx%#==#WinDir# goto setdir
set y=%@eval
goto loop

:setdir
set winx2=%@substr
set winx3=%@substr
%winx3%
cd %winx2%
path %winx2%;%winx2%\command
set x=
set y=
set l=
set winx1=
set winx2=
set winx3=
set winx=
WIN /D:N
:error
echo ERROR ! windows_9x_Path unknowed !!!
echo 1.THERE IS NOT C:\MSDOS.SYS!
ECHO 2.C:\MSDOS.SYS can not load Windows9x!
ECHO Press any key to continue!
PAUSE>NUL
goto end
:end
endlocal
quit
