I bet fd0a is a 5.25" floppy, right?
For some reason and with some models of floppy drives, when you boot off of
a 5.25" floppy, it's in a weird state at boot time and doesn't get probed.
This problem has been around for a while (why haven't I sent in a PR on it?
I haven't had a chance to investigate it much). This can probably be fixed
by strengthening the probe code in fd.c.
