Lotus 1-2-3 R3 is indeed looking for *extended* memory and using protected
mode.

I didn't mention it, but we did try an Award bios in the first machine, to
no avail.  Dell is shipping us their latest bios, but we don't have it yet.

Interesting.  I'm not familiar with either of these schemes, but I had
noticed that 1-2-3 seems to use protected mode differently than another
"extended" application that we have (which works).  The protected
application which works is using RT's DOS16M extender.  It loads an 83k
kernel in conventional memory, and loads the remaining 2 megabytes of code
and buffer space above the 1 meg boundary.

Lotus is supposed to work with a single meg of memory, utilizing additional
segments between 640k and 1 meg.  If you have additional extended memory, it
will use that also.  As I said earlier, we haven't been successful with
either configuration on the PCs LTD 286 machines.
