Ok, how to force C compiler / linker (Keil) to produce code beginning at (say) 8000h?

I use it only on the command line:

C51 ... INTVECTOR(0x8000)

L51 ... CO(8000H)
On the IDE there must be some menu points similiar to it.


I used also memory switching on some of my projects. To avoid malfunction I use the following approach.
there is a 3th memory area which was always on the same address independent from any switching signal. The code to switch the other memory devices, was executed only in this 3th memory. So the affected memory devices always disabled during switching.

As suggested hold in reset during switching seems also reliable, but then switching can not be made by software.
