Enhanced CONFIG.SYS Options
DOS 6 provides the following enhanced configuration options:
MultiConfig Menus
New CONFIG.SYS commands make it possible to display an interactive
menu of configuration options. Different sets of commands can be
executed depending upon the user input. DOS provides a way to
specify a timed default selection and a way to continue along a
particular boot path in the AUTOEXEC.BAT file.
┌──╖
│F5║ Clean Boot
╘══╝ At system startup, you can press F5 (or press and hold SHIFT) to
bypass the commands in CONFIG.SYS and AUTOEXEC.BAT. This can get
you out of a tough situation in which a configuration problem is
causing a system lockup. DOS 6.2: Ctrl+F5 also bypasses loading
of DBLSPACE.BIN.
┌──╖
│F8║ Interactive Boot
╘══╝ If you press F8 during system startup, you will get a chance to
step through the commands in CONFIG.SYS one-by-one, skipping any
commands that are causing a problem. This option also lets you
bypass execution of AUTOEXEC.BAT. DOS 6.2: Ctrl+F8 lets you
process individual commands in AUTOEXEC.BAT.
cmd?= Place a question mark (e.g., DEVICE?=RAMDRIVE.SYS) in any
CONFIG.SYS command to be prompted whether to execute that command.
;(rem) Semicolon at the start of a line indicates a remark.
SET With DOS 6.0+, you can create environment variables in CONFIG.SYS.
