No problem.

I wonder if we can go the other way and use void for all labels without
storage.  Indeed, it's too easy to misuse a char variable by forgetting
the ampersand before it.

I agree that we should avoid touching the hardware.  Besides, after
loading ata we may not see some drives that BIOS can see.

Validation of user input is good, but only if it's implemented
correctly.

Another approach may be to use biosdisk calls only if biosdisk is
active.  Otherwise, trust the user and turn off validation.
