Using Config.sys for System configuration

The computer will automatically look for Config.sys this file when it starts, without it, the computer will run in the default way, but this default is not the most suitable for computer use, so we should set up the computer, such as the use of extended memory, loading the drive driver, etc.

If your computer appears to be unable to use, the game reports the memory is insufficient, the optical drive cannot find, cannot connect the network and so on the mistake, the reasonable modification Config.sys may solve more than half of the problem.

Config.sys is a text file that can be edited with any editor. If you add, change, or delete any of the configuration commands in the Config.sys file, the change will only be effective the next time DOS is started.
