If you use isolinux you are booting with El Torito in "no emulation" mode,
while if you use a floppy boot image you're likely booting in "floppy
emulation mode". Maybe that bios is ok with emulation mode and not the other

The advantage of isolinux is that you can ignore the limits of floppy images
(large initrd's)  and/or choose at boot which floppy image to boot.

However, if all you need is the equivalent of a floppy image on CD, you can
produce the image with mkisofs and a floppy image (maybe with syslinux)
without using isolinux. This would be more similar to what those windows
users did.
