During boot, the loader uses the bios-supplied routines to load the
kernel, modules, and md root. One would hope the bios knows how to
communicate with its hardware.
By the time sysinstall is running (from the preloaded memory disk), the
kernel has mapped all the hardware it knows, and no longer utilizes the
bios routines for I/O. Thus, if FreeBSD knows not of the hardware
connecting the CD drive, it will not be able to present it as an option.
Fortunately, once you get this far, you need not actually use the CD to
install; network installation works quite well.
