Help!
I've got a MULTIBUS development system which runs under XENIX.
I've also purchased, for this system, some memory-mapped boards ( an
analog input card and a single board array processor ).
My problem is this: these boards are configured into the system
to look like ram ( they have PHYSICAL memory addresses ) but XENIX
forces ( ? ) me to stay in a LOGICAL addressing environment.
How can I read from / write to physical memory from XENIX or a
C program ? What does it take ?
Any advice / guidance will be appreciated. Reply in this
