If You want to '''create a bootable CD/DVD from floppy image''' (for ex. to update BIOS in IBM ThinkPad T40) You should follow this steps: <br><br>

'''1.''' You need a floppy image for ex. '''''NAME_OF_FLOPPY_IMAGE.IMG''''' <br>
'''2.''' You need the '''''mkisofs''''' <br>
'''3.''' You need just to run following command: '''''mkisofs -pad -b NAME_OF_FLOPPY_IMAGE.IMG -R -o /home/your_user_name/cd.iso /patch/to/the/image/file/NAME_OF_FLOPPY_IMAGE.IMG''''' <br>
'''3b.''' If the above command doesn't work for you try this one:  '''''mkisofs -b NAME_OF_FLOPPY_IMAGE.IMG -o bootcd.iso NAME_OF_FLOPPY_IMAGE.IMG'''''<br>
'''4.''' What is what: <br><br>

'''''-pad''''' &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Add padding to the end to make it readable on all CD players <br><br>
'''''-b NAME_OF_FLOPPY_IMAGE.IMG''''' &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; -b tells mkisofs which *floppy image* to use for booting. If the floppy image boots as a floppy,it will boot<br> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;   as a CD. Note that there is no path prepended to NAME_OF_FLOPPY_IMAGE.IMG.<br> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;   The NAME_OF_FLOPPY_IMAGE.IMG bootable image is assumed to be relative to the file being imagized, <br> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;  in this case /patch/to/the/image/file/NAME_OF_FLOPPY_IMAGE.IMG <br><br>

'''''-R''''' &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Include Rock-Ridge extensions for readability everywhere <br><br>
''
'''-o /home/your_user_name/cd.iso''''' &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; This defines the output file, an ISO9660 image ready for burning <br><br>

'''''/patch/to/the/image/file/NAME_OF_FLOPPY_IMAGE.IMG''''' &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; This is the file to put on the CD.
