Hard disc based booting is *NOT* only a DOS thing ! I know no workstation 
which boots from ROM. Also I didn't meen to replace the ROMboot, I only meant 
to expand it to be *able* to boot from HD, no need to do this if it's not 
needed (RiscOS) !

May be I'm a purist, but I don't get the sence of let two operating systems 
check the hardware if only one will run. It only costs time.

I did this some time before and it worked. But my understanding of a operating 
system is, that it is able to boot itself without the need of another OS. 
However ...
All you said above I've done long ago and removed it again because I often 
need to run windows95 and this is not possible from within RBSD. Anyway, pure 
MSDOS soft without graphic I could run now under BSD, but only at 125% speed 
of a 4,77MHz ancient IBM-XT and only with UK keyboard mapping. Not really what 
I want ...


Anyway, the RiscPC is not a workstation, therefore there is no need to discuss 
this thread further.



Ciao, Peter
