If you want to write a larger floppy, you can write upto 1.722MB using
the device /dev/fd0u1722. If it doesn't exist, create one thusly:
	mknod /dev/fd0u1722 b 2 60

I had heard that CDROM boot specs require that the boot image be 1.44MB.
I'm not sure about that tho'; maybe someone else can comment on this.
