If the 2M of memory is actually addressed at 1M to 3M, then 1-2-3 won't
see it, because DOS doesn't see it.  1-2-3, version 2, is designed to
work with the Lotus/Intel EMM specification.  It is 64K paged memory
residing, I believe, between D0000 and E0000.

Yes, the 286 and 386 machines can address that much, but poor old DOS
can't.  The OS/2 operating system will see that memory, as well as UNIX
operating systems for ATs and 386s.

If your salesperson sold you the PC with the belief that the extra memory
was usable, he is mistaken.  Even machines that come with 1M can't get
at the stuff above 640K, except for some spooler programs and PC-DOS's
VDISK program.

Sorry to bring you bad news, if someone else hasn't already.
