I would like it if the keypress was optional, too.

A few words about my application, since I'm not sure it is supported
by cdboot today.  I have some unattended wireless routers whose BIOS is
too dumb or broken to boot from CD-ROM.  I would like to put the cdboot
primary bootloader onto a floppy disk; the secondary bootloader, kernel,
and ISO9660 root will go onto the CD-ROM.  There might be a bootable
hard drive---or a CompactFlash card, at any rate.  Is this something
that cdboot will support?
