Hi Mr Anvin, I'm using your isolinux.cfg file in Bart's CD creating files, and was hoping you could help me with something. When the CD boots and you're shown the menu (which is from your isolinux.cfg file I think), I'm hoping there may be a command that I can use with your isolinux.cfg file to check for a specific file on the primary hard drive (Like the old DOS IF EXIST command). If the file IS found, I want to call a DOS batch file which will execute a particular command. Otherwise, if the file is not found, simply go to the next default boot menu item shown in the isolinux.cfg boot menu (which is the primary hard drive). Do you have any suggestions on how to do this or can something like this be done using the isolinux.cfg file? Thank you. Craig Caughlin
