All the calls are standard but we don't checked if some flag allows to the BIOS 
to say that some of the functions isn't supported. Perhaps the CL5446 lack the 
routine to save/restore the board registers.

If you (Robert) don't understand it I'll clarify:
He wants to force a restore of the same mode that was set when RHIDE started. 
So if he enters in mode 3 and leaves in mode 0x101 he wants that RHIDE restore 
the original mode 3.
