Question:Can I boot from a floppy disk and install Linux from an external USB2.0 Drive

Hi,

If I had made a linux file system on external USB2.0 drive then download
the latest version of the Linux installation image files on it for friend's
brand new machine Linux installtion, is there a specific boot floppy disk
with USB driver built in for external USB drive installation.

I knew the network boot disk can allow to do that installation on the local
area network using the mounting way. But if this brand new machine is just a
stand alone machine. If there is a way to do the installation using USB
drive, then I can avoid the tedious buring CD image process and save couple
cents.^_^

Please help me.

Thanks in advance.
