I amlooking for a memory manager for a 286 with an EGA card to extend base 
memory 64K.  I have checked Simtel and all they have is stuff for use with
CGA(sorry that's not an option). I have 1Meg with ems 4.0 compatable and need
to run a program that uses 640k and a res driver that needs 64k o top of that.
I really don't want to by an All Charge Card.
