So change the CMOS-settings so that the BIOS changes the boot order
from A, C, CD-ROM to C first instead. *grin* How long do you want

Of course, using capabilities and totally disabling access to the raw
disk devices and to any I/O ports might be the solution, provided that
there are no bugs or thinkos in the capabilities code.
