Hi,
Here you go:
1> Make a bootable floppy and make sure it works fine (boot through it)
2> In Nero, check the option of Bootable CD
3> Use Nero to make an image of the boot floppy
4> Since Bootable CD's can't be of multisession, drag and drop all stuff (98, Acrobat, whatever you wish) into the compilation
5> Burn (the disc
This is what I do, so I think it should work for you too!
Bye!
