in what mode are device drivers in config.sys loaded from? and autoexec?

Answer 1

DOS.. AUTOEXEC.BAT is the name of a system file found originally on the MS-DOS operating system, although it still exists in many Microsoft Windows installations. It is a plain-text batch file that is located in the root directory of the boot device. The name of the file is a portmanteau of the words "automatic" and "execution", which describes it's function in automatically executing commands on system startup.... CONFIG.SYS is the primary configuration file for the MS-DOS and OS/2 operating systems. It is a special file that contains setup or configuration instructions for the computer system. The commands in this file configure DOS for use with devices and applications in the system. The commands also set up the memory managers in the system. After processing the CONFIG.SYS file, DOS proceeds to load and execute the command shell specified in the shell= line of CONFIG.SYS, or COMMAND.COM if there is no such line. The command shell in turn is responsible for processing the AUTOEXEC.BAT file.
