backup to a network drive, then restoring

I need to delete all partitions on my system, and have already backed up the entire system to a network server. I want to then delete all partitions, reformat and then reload my software. Will this work, as long as I make a floppy copy of the system registry, and then reload?

The other issue is how to regain access to the network after I rebuild the drive, without having to first install Windows 95. Can I make a system bootable floppy that will also grant me DOS based networking and access?

Thanks for any help. Please also reply to my email address at drjones@mail.vii.com
