P> SUBST is a command file widely used in the DOS era. Its function does not need to be repeated. From DOS to today's Windows XP era, we have gone through the Windows 3X/9x/ME/2000 series operating systems. The advantages of windows have long forgotten that we still have dos, can we still use it now? SUBST can play the following roles at least in the Windows operating system: 1. Reduce the wait time for the hardware driver to be installed without the software drive system; 2. easy for users to m

the complete path must be entered here. (6) files in "scanreg. ini "has the following annotation content"; Files = [dir code,] file1, file2, file3 ", remove the annotation symbol, you can DIY the important files that need to be backed up by the Registry check program. By default, when the Registry check program creates a registry backup file. dat "," system. INI "," user. dat and win. INI files are stored in the "cab" compressed file. If you need to add other important system configuration file

system may fail to start properly ), using the "Last correct configuration" to start Windows generally solves these problems. Of course, if system problems occur due to system file loss or damage, it cannot be solved (in this case, you can enter the System Configuration Utility and click "Expand file" to extract the corresponding file for recovery ).7. Directory Service recovery mode: This mode is used to restore the sysvol directory and Active Directory Services on the domain controller. It is

environment, allowing you to build a Java solution that uses standard APIs as the core. However, the only thing your network server needs to apply to JSP is the Java compiler. To let the network server know the compiler location, set the environment variable java. Home to the jsdk installation directory. If you install and accept the default directory on Windows, add the code set java. Home = C: 1.2.2 to your autoexec. BAT file and restart the file.

. Delete autoexec. BAT and config. sys. The system installs the autoexec. BAT and config. sys files under the root directory of the disk. If you do not need them in Windows, you can safely delete them to speed up windows startup. 10. Streamline the *. ini file, especially the content of system. ini and win. ini. Many drivers and font files are loaded in the [boot] and [ENH] sections of system. ini, whi

Each time the system starts, the files are automatically run. You can put the commands to be run every time the system starts, for example, you can set the search path, call the mouse driver and disk cache, and set system enviro

It is worth a look The method for installing the dos nic Driver is different from that for Windows. For example, the model of the NIC in Yanhua 3355 is, the amount, and cannot be remembered ,,, boot bios, you can see that the driver is. COM file, The file name is "e100bpkt. com ", in

The bootstrap loader program and self-diagnosis program stored in ROM (read-only memory) are moved to Ram (random memory. 2. As bootstrap loader runs, the operating system stored in the auxiliary memory device sends system files to ram. 3. Execute the system file IO. sys and msdos. sys.

the child version of V1.1.2.1 Version 1.0 ·DOS V1.0 is the most primitive system that supports PCs. It supports basic Single-sided, eight-sector (eight-sector DiskAnd provides all basic disk services. The major change (relative to CP/M) is that it includes support for magneticDisk directory structure, File Attribute management, and file size. Version 1.0 has also been improved against the original 86-DoSDisk allocation and management functions, better operating system service programs and

Right-click the created shortcut and select Properties to enter the program bar. In the running box, select minimize and tick before "close upon exit.

For a microcomputer with a hard disk, you can set the priority of the two methods by modifying the CMOS. If the priority is set to "A:, C:", you must first check whether there is a dos system in drive A at startup, and then start from drive, if no, search for the DOS system from hard drive C. If the priority is set to "C:, A:", search for the DOS system from hard drive C at startup, if no

Most programs in the DOS environment run in the regular memory. If a program fails to run due to insufficient memory, the most common problem is that the general memory is insufficient. The following describes several common methods to release the regular memory: 1. When the system is configured with extended memory, you can install most of the DOS code and the temporarily resident memory of Command.com in the high memory zone (HMA ). This requires that the following commands be included in con

CLASSPATH both specify the PATH list. The items in the list (that is, each PATH) are separated by separators. In Windows, the Delimiter is a semicolon (;), while in Linux, The Delimiter is a colon (:). The following describes how to set the three environment variables in Windows and Linux, but before that, we need to make a hypothesis. Assume that the JDK installation path in Windows is C: jdk, and the installation path in Linux is/usr/local/jdk /. The installed JDK will include at least the fo

metacharacter, so the dot in the middle of the file name needs to be put into a character class to remove its special features. At the same time, pay attention to the end of $, which is used to ensure that the rest of the string is included in the extension. This regular expression matches foo. bar, autoexec. bat, sendmail. cf, and printers. conf. Now, consider a slightly complicated situation. If you want to match a file name whose extension is
