Part of HDDRIVER I guess.

It could have affected the "no TOS screen output". I compiled a fresh
Hatari and pure TOS/BIOS console output is still not shown. (At least
not if launched from desktop, AUTO folder progrms show their output)

The files are certainly not read-only and I do not have any --protect-hd
option enabled.

I can try over the weekend. I will have to compile Hatari with working
debugger first (or is it active by default now?)
