In setting up an 8e on 5.0.5 I couldn't find a memory window that worked using mpi (3 versions).
The memory search program (DOS based) indicated E800 was available but mpi only listed E000.
I resolved my immediate problem by changing the window value in /etc/conf/pack.d/pcxx/space.c prior to relinking but mpi retains the value I had left in it prior to the manual change.
My question: where does mpi get the memory window values that it displays during setup and how can the values be changed?

This card uses 64K of memory, and tries to install itself on 64K boundaries, so I would presume that the program only looks for available memory at [A-F]000.
By changing the starting address to E800, the card will use E800-F7FF, which may or may not cause a problem.

It will try to map itself into 64K but will map into 8K if that is all it can find. Except that in this case it mapped into a couple of the 8Ks that it thought were free (separate setups) but couldn't find them on the next reboot, wouldn't find a 32K block that was free, and would have been considered a broken board if I hadn't decided to look in the space.c file that mpi created. The last page before starting the relink has a message that it has rebuilt pcxx (or pcxi, whichever has the space.c file) and that was when I decided to look at the file and to modify the starting address.
I've run across issues before where boards wouldn't find a usable window and have always had enough spares to get by. Now that I've had success at pulling one back from the trash bin I'll revisit the issue with some of the other questionable boards that I've saved. It may be a while, until I rebuild my testbed.
