Hi David

The CDROM "standard" installer and CDROM "legacy" installer are the
only images that you can write to CDROM. If you are having problems
with the CDROM "standard" installer, then you should try the CDROM
"legacy" installer instead. The standard version works on most
machines. Some machines (notably, older PCs) need the legacy version.
The only different between standard and legacy is the boot method.

The boot floppy is meant to be used *with* a CDROM, but not *as* the
CDROM. Some computers (again, usually older PCs) cannot boot from
CDROM. For these computers, you write the CDROM installer to a CDROM,
and write the boot floppy image to a floppy disk. Then boot the
computer from the floppy, then insert the install CDROM when the
install program starts up.

The boot floppy image is only meant to be written to a floppy disk. So
that's why your software says the boot floppy image is not a valid ISO
- because it isn't meant to be.

Another helpful note from my other email to you:
