Re: Autoexec problem
If you want a global environmental variable you need to use the System applet in the Control Panel to set it up. Variables set up in the autoexec.bat file are usually only going to be present in DOS emulation sessions because the autoexec.bat file isn't normally processed during the Windows XP boot, starting a DOS emulation (Command Line) session is when that file gets processed.

It's perfectly ok to use a cd writer as a cd drive, the drive will likely outlast your computer anyway.
