Re: COMMAND.COM on a RAM-disk

Here's how I do it:

1) Edit your CONFIG.SYS to contain the line:

	shell=c:\command.com e:\ /p  /e:62
	      ^^^^^^^^^^^^^^ ^^^ ^^  ^^^^^
	      =======1====== =2= =3= ==4==

   What this says is:  
   =1=  load COMMAND.COM from the root directory on the boot disk (C:)
   =2=  do re-loads of the transient part from E:\ (which is the
        RAM-disk; insert whatever drive letter YOU use for this purpose)
   =3=  signifies that this is the permanently loaded copy, which means
	that it will execute the AUTOEXEC.BAT file
   =4=  this has nothing to do with the problem, but use the 
	opportunity to increase your environment space; the value
	selected depends on what version of DOS you have

2) Insert the following lines EARLY in your AUTOEXEC.BAT file:

	copy c:\command.com e:\
	set compsec=e:\command.com

From this point on, the DOS should look for itself on the E: drive, AND 
other programs that you have that escape to a subshell will find the new
COMSPEC environment variable and load from the location indicated therein.
