Hi.

I compiled cdboot, /usr/src/sys/arch/i386/stand/cdboot (fresh CURRENT sources) and used it with mkisofs to create an iso image
# mkisofs -l -J -R -nobak -no-emul-boot -o myiso.iso -c boot.catalog -b cdboot cdimage/
After boot from CD, cdboot it will fall back to HD boot if you don't press any key.
Why ? If I chose to boot from CD, why would I want to boot from HD if I dont press any key within given time?
Maybe adding some informative text or menu like the FreeBSD's one would be in place?

Cheers
