I'm not trying to be a wisea**, but the fact that you haven't listed
interrupts suggests that you may have something to gain from further
study of TSRs. ;)

Please understand that I don't know the answers to many of your
questions. I _do_ know that the answers can probably be had in the TSRME
package I mentioned, along with methods for swapping both the TSR and
the "running program" to and from EMS in addition to disk, passing
messages among TSRs, checking for installation of specific TSRs,
uninstalling TSRs, etc.
