Microsoft DOS switches
Loaded in the config.sys switches allows you to add and remove various functions of MS-DOS.
The switches command is an internal command that is available in the below Microsoft operating systems.
SWITCHES= /F /K /N /E[:n]
|/F||Skips the two-second delay after displaying the "Starting MS-DOS" message during startup.|
|/K||Forces an enhanced keyboard to behave like a conventional keyboard.|
|/N||Prevents you from using the F5 or F8 key to bypass startup commands. (SWITCHES /N does not prevent you from pressing CTRL+F5 or CTRL+F8 to bypass Drvspace.bin or Dblspace.bin; to prevent this, use the D**SPACE|
|/SWITCHES||Command to add the SWITCHES /N setting to your D**space.ini file.)|
|/E[:N]||Used without the :n parameter, indicates that Io.sys should suppress the automatic relocation of EBIOS. (Automatic relocation of EBIOS increases the conventional memory available to MS-DOS-based programs.) Suppressing automatic relocation results in less conventional memory available to MS-DOS-based programs. Use the /E switch with the n parameter to relocate N bytes of EBIOS to low memory, where n is the number of bytes to be relocated. The minimum value for n is 48 and the maximum value is 1024. The number specified is always rounded up to the next multiple of 16.|
