Just a followup in case there is any confusion:
1. the existing EmuTOS code works OK on Hatari, but not on real hardware, so 
I'm fixing it.
2. with GCC optimisation off, the new EmuTOS code works fine on real hardware.
3. with GCC optimisation ON, the new EmuTOS code gets a timeout error when 
sending a read command to read certain specific sector numbers.
4. there are no problems reading the same sectors with TOS.

So I'd like to debug the optimised code on Hatari ...
