LinuxQuestions.org - boot and install linux via usb

Currently I have Siemens Industrial Linux version 2.4.36. It runs on an old system which gets installed via floppy disk & MODs.

To install this Linux, I have to insert floppy disk which contains the Linux boot information & kernel setup. After inserting floppy, and after some processing, it asks for the MODs to insert. The MODs contains some folders & those folder contains a lots of `.rpm packages. Sample is like this\

Code:

gcc-2.95.3-5.i386.rpm

gdb-5.0-2.i386.rpm

ltrace-0.3.10-4.i386.rpm

python-1.5.2-11.i386.rpm

tkinter-1.5.2-11.i386.rpm

..

..

There are 2-3 MODs present. After inserting floppy disks, it asks to insert MODs. After inserting MODs, the booting & installation process gets completed.

Now what I want is that instead of installing this Linux, I want to boot & install Linux through USB since floppy disks are a very old technology & are very rarely available.

It is best to use USB. Currently I boot other latest Linux like CentOS & Ubuntu using unetbootin. These Linux comes with a single build bundle, but Linux I above mentioned divided onto floppy disks & MODs. How can create a single bundle to boot from USB ?

The Siemens Industrial Linux contains some preinstalled specific softwares used to run machines which I specifically don't know how many.

So is it either possible to run my system through any latest Linux like CentOS instead of that old one ?

Thanks
