I ran into a situation where I need to use a DOS program but it will not run if himem.sys is loaded. Unfortunately, I (likely) have other things that require it. This is my config.sys [COMMON]DOS=HIGHSHELL=C:\COMMAND.COM C:\ /P /E:512DEVICE=himem.sysdevice=ifshlp.sysIs it possible, via .bat, to unload himem.sys so that the program can run if it is selected?
