The goal is to use virtual floppy so I can install Fedora on a VM very fast.
Create a floppy image using Winimage software or VMware.
Winimage is very self explanatory. When you use VMware add a floppy device to the a VM, select create a floppy image, boot the system and copy the anaconda cfg file to the disk.
Install linux, in the first screen push ESC, and enter the following line:
boot linux k=hd:fd0/anaconda.cfg
It depends on the info in the file that if you are going to have to add more info in the install screens. Installation can be fully automated. For more info click here.
