|Do you have a CD burning program such as Roxio or Nero?|
If so, there is an option to make the disc bootable. I'll walk you through how to do it in nero, i don't know about Roxio but it should be similar.
Put your Win98 floppy disk in th drive and launch Nero. When it gives you the option to select what type of disc you want to make, select CD-ROM boot. Select Bootable Logical drive and it will use the floppy disk boot sector to make your CD bootable. Now in the main window of Nero, point it to the A drive and select all the files on the floppy and drag them to the CD window. Now burn your disc.
