Linear mapping is already possible with the Tseng ET4000.  It's a smart
idea.  However,  let's not make the mistake of FIXING a certain location
for a single purpose.  Let's DEFINE a standard which allows CRT adapter
memory to be mapped into memory anywhere we wish and make sure software
does not EXPECT the video memory to be at at say E000000H.  This way
when by year 2000 we are looking at the 4 gigabyte RESTRICTION, we
won't be bitching about whose idea it was to design something like
a fixed 128 megabyte video memory allocation.

Aki.

PS. 4 gigabyte RESTRICTION a myth??  Just wait and see.  Intel created
address space so we could run out of it.
