Create a similar config.sys file on your boot disk. Please note that if you have anything other than this, you will have to create your own, based on what is loading in the config.sys file. Yours may be similar, but loading different modules depending on your zip drive type. You may not need all this for your boot disk. I have a parallel port external zip drive, here is the config.sys file that I am using for my own DOS boot disk.
Instructions are in the ReadMe.txt file within the .zip file ZipBoot.zip.
Be sure to read them carefully.
