That is *JUST* how extended memory is often used on so-called AT
clones! For example, an AT&T 6286 I sometimes use has a little
over a million characters of random access memory.  Unaided
MS-DOS recognizes 655 000 characters of that.  The machine is
configured to use 131 000 characters of the remainder as
"shadow RAM" for storage of read-only memory routines and video RAM.

Windows/286 has drivers for using the extended memory as if it were
normal memory, and/or as a disk cache.

Now the question is:  Will utilities that allow use of extended memory
on other machines work on Rainbows?

A side note: Note that all Rainbows have static RAM for use as shadow
RAM of non-volatile
memory.

My Rainbow has the color option, but some programs call for REGIS, what
is it? Where do I get a copy.

   David, please note that "extended" memory in the area of PC
compatibles has a rather specific meaning - memory whose addresses lie
above 1024KB (ie, 1MB) - and as such requires a 286 or better. As I
don't believe the memory board from SS requires a 286, I doubt it
contains so-called extended memory. Keep this in mind in your search
and it will likely be less frustrating.
