This works on Windows 2000 but don't have DOS or Win9x to try on for you... but should give you something to work with.

Sorry, but not everyone on the board is that old... [Razz] And since this is a KiXtart board, some don't venture too much beyond KiXtart help.

Oh Well, give something like this a try.
code:
@echo off
IF EXIST a:\NUL echo found something in the A drive
I assume you know how to run this from KiX, if not post or look in the FAQ and I'll show you how.
