can't make a CD bootable

Hello,
to copy a CD of data I do:
mkisofs -R -r -J /cdrom | cdrecord -v fs=6m speed=4 dev=1,0 dev=1,0 -
and all works fine.

But now, I want to copy a CD bootable.
man mkisofs gives the option: -G generic_boot_image
I don't figure out what is generic_boot_image

How must I pass the option -G in my previous command ?
tia.

Did you get an answer? The way I would do it is to (a) find the length
of the ISO filesystem, and (b) burn it as is.
  dd if=/dev/cdreader bs=2k count=$NumSectors | cdrecord ...
Or copy it to disk if you have a single CD device.
