I sent this to freebsd-drives too but I think that might not be the right
list for it so here it is: I am starting to learn how the kernel works and
have started by going through the boot loader and I've noticed that between
lines 21-32 in boot0.S there are some empty #ifdef statements. I was
wondering a) where are these paramaters defined and if they are defined,
what difference does it make since it looks like it doesn't change anything
since they're empty?
#ifdef SIO
#endif
#ifdef CHECK_DRIVE
#endif
#ifdef ONLY_F_KEYS
#endif
These seem to be there to act as reminders for command line options which
can be used to build boot0. They're also documented in Makefile.
These are actually used later in the code.
